Does the human body regenerate every 7 years?
We regenerate constantly in a way, in terms of cells. I'm going to give an answer that strays this topic a bit, but it should help you all understand . We don't regenerate in that sort of aspect. Our cells multiply (which is a form of regeneration because mostly when our cells multiply most of the old ones die after a while, and there are small string like things attached to each cell that over time (in terms of ageing and multiplying) get shorter and shorter untill it runs out and leaves the cell open causing them all to burst or defect) (death by old age) this can even kill you if your medically healthy and is just the way of life. Unless we can preserve these cells or live without them, living over 120-30 is pretty much impossible. Oh and may I add that the multiple rapid cell regen (some forms of cancer) is so hard to survive for a long time is because if its left for too long our cells will multiply so much either causing burst or defect, or overloads. I hope I explained this okay - basically we don't regenerate in the form you are talking about, but we are constantly regenerating/forming new cells which is somewhat a form of regeneration

Pay, salary, or even earnings depends on whether the person isworking or retired. A retired person has no salary or pay but mayhave yearly earnings from investments. However, the pay or salaryfor working personsn varies widely depending on the job,experience, or even pay grades.

The amount that a human body will grow in a year is directlyrelated to the age of the person as well as gender and availabilityof food. The highest growth rate is from birth to age 1 when thehuman body averages a height increase of 10 inches and triples inweight. Children typically experience growth… spurts rather than acontinuous speed of growth. (MORE)

A Red panda cannot regenerate any body parts. There is no knownpanda in the world that can regenerate any body parts.
The same question was asked at another site and this was the answer given: As an example, on average a normal, healthy individual who donates a unit of blood (about 450 ml or Â¾ pint) will fully recuperate from the blood loss in four to six weeks. The issue is a bit more complicated than that… though. You see, our blood is made up of a variety of things: Red blood cells that carry oxygen from the lungs to all other tissues in the body. White blood cells that provide the body's defenses against disease. Platelets, specialized cells that plug damaged blood vessel walls and join other elements in the blood in the production of clots to stop bleeding. Plasma, a yellow fluid made up of about 92% water and 7% vital proteins such as albumin, gamma globulin, and antihemophilic and other clotting factors. And other elements consisting of mineral salts, sugar, fats, hormones, and vitamins. Red blood cells, white blood cells, and platelets account for about 45% of the volume of blood in the body. The remaining 55% is plasma including the other extraneous elements I mentioned. The four to six-week period I indicated a moment ago is the time necessary to replace ALL these factors, though our bodies actually replace some of the individual components faster than others. For example, the fluid (mostly water) lost in a blood donation, is replaced in only a few hours, provided the donor drinks a moderate amount of water or healthy, non-alcoholic liquids to replenish the loss. The other components of the blood, such as platelets and red cells begin to replenish immediately but take a bit longer to complete; usually within a few days or weeks depending on how much blood is lost. Generally speaking, after donating a unit of blood, the body replaces the fluid and white cells within 24 hours, and platelets and plasma proteins within 48-72 hours. The red blood cells are completely replaced in 4-6 weeks. It would be safe then to say that a blood ?sample? (rather that a whole unit) or a small amount of loss due to a very minor scrape or bleed could conceivably be fully replaced in a healthy individual within hours. How fast the entire blood loss is replenished obviously depends on the amount of blood lost, the size of the individual (for every 12-15 pounds of body weight, a human being has about one pint of blood) and the health of the individual from whom the blood is removed. If the body is functioning normally and there are no extenuating circumstances (interfering medication, unhealthy lifestyle or diet, etc) age alone should have little or no impact on the natural replacement of blood. A poor diet or sedentary lifestyle can however have an impact on how fast the body replaces blood because of the necessary nutrients in a proper diet that enable the cell replacement. Lack of exercise, for example, can lead to obesity (and ultimately the need for more blood than normal) and can certainly cause arteriosclerosis or other venous constrictions than can complicate blood flow, adding to difficultly or delayed replacement. This of course is just one hypothetical situation, but there are others. Replacement is also relative to size and exercise (or lack thereof) If a pint of blood is a significant portion of a person?s entire blood volume (as in a newborn for example) it will take longer for the body to replace half the blood volume. In a 500lb man, a pint of blood is not that much in terms of overall blood volume, BUT his body may have a difficult time replacing that pint in the normal range of expectations because of his morbid obesity and other health factors. So you can easily see how diet and excercise can affect blood replacement. As a rule though, if you are relatively healthy, eat right more often than not, and even moderately exercise you can expect a fairly predictable and complete replacement of a non-life threatening blood loss within the time frame I specified regardless of your age.

If you average all the cells as they live, multiply, and die, many sources say that it takes seven years for all of them to change in your body. This is somewhat true, but also somewhat misleading. The truth is that different cells have different lifespans. For example, the nerve cells in your brain… do not multiply and they last for your entire life. If any of them die, they do not get replaced.. At the other end of the spectrum are the white blood cells in your body. They have the shortest lifespan and some of them live only a few days. So, in actuality, the concept that your body changes every seven years is not exactly true, because even though most of your body cells will have reproduced and replaced themselves, not all of them have, and some have replaced themselves many times over during those seven years.

Human limb regeneration is not fully possible at this point in time. The reason is that certain cells cannot be restored or "regenerated". For recovery of limb loss cells must be taken from another body that is alike to the one with limb loss. Stem cell research is the closest thing humans have gott…en to regenerating and yet it is not funded but this is aside from the question. If a human were to regenerate a limb on its own it would require a extreme excitement of the cells healing the body and would dramatically shorten the life-span of the one recovering. The fact of the matter is, every injury and every moment we spend recovering from tissue damage leaves less cells to regenerate the body and provide a life-span and use of cells. (MORE)

umm...our bodies are designed to fix a wound such as a cut or burn. so if you were to break a bone or something then i think that the body would naturally regenerate bone. but say if you were growing then your body needs to generate bone to compensate for your growth. and if you want to have strong …bones, then of course drink alot of calcium rich drinks such as milk.

yes...they can. I have a small frog in my backyard that I absolutely adore! Crazy I know, but he comes around at the same time every night and just kinda hangs out on the porch. I was planting some flowers around June, and when I put the shovel in the ground this little frog jumped up and it only ha…d three limbs. I realized that I had cut it with the shovel, and felt horrible. He survived, and still comes around everynight. I have been watching him, and he has begun to grow a stump from the area that his front leg/arm was missing. It has tripled in size in the past few months, and he is beginning to use it as if he had a normal arm. I researched amphibian regeneration and found that yes, it is possible. They form a stump called a blastema on the site of detachment to form the basis for the limb, and eventually a normal, scar free limb will replace the old one and have fully restored function. (MORE)

It is often said that one dog year is equivalent to seven human years, because that is the rate at which young dogs mature. A two year old dog is the equivalent of a forteen year old human adolescent, for example. This equivalence does not correlate quite as accurately with respect to aging. Dogs of…ten live to be 20 years old (or more), which if we apply the formula would be equivalent to a 140 year old person, which is extremely unlikely (very few people live to be more than 100 years old).

No. Half of the planet would be in sunlight (day) while the other half would be in darkness (night), just like the Earth, with the exception of its rotational speed, which is about once every 243 Earth days, instead of Earth's 24 hours.
to die is to live no longer, you cannot regenerate when you die, your heart no longer beats, your brain is no longer active, you'd have no life, ever lean or lay on your arm too long and theres no blood that goes into it? and all you feel is numbness and its heavy? well, take that as an example of w…hat your body may feel like after your dead.

An answer to another question stated your body changes every 7 years - what that's all about ...the question was What does a sporadic pain behind the ear in the back of the head mean?
The statement that your body changes every 7 years is an oversimplification of maturation and aging and is not an accurate statement. Sporadic pain behind the ear and in the back of the head can be anything from a tension headache to a tumor. That is not enough information to make a diagnosis. The …fact that it is present only sporadically is reassuring, but you should see a physician if you want to know the significance of your symptoms. (MORE)
No. A leopard is able to grow back lost skin or tissue, but if a leopard loses a limb, it will not grow back.
Yes, I chopped of one of it's legs and sure enough in a weeks time it had grown back... if they lose an eye they will grow 5 in replacement.
Doctors have told me this for years, but the one who prescribed my barbiturate yesterday said it wasn't true. He's a great doctor and been around for years, so I'll take his word over the others.
49. 1 dog year = approximately 7 human years. 49 years old 1 human year=7 dog years
Once puberty is begun, the body continues to make new sperm every day of a guy's life until the day he dies, so you never have to worry about "running out."
Yes they can, because their body parts are so simple that it's easy to duplicate. Humans, on the other hand, are complicated (muscle structure, bones, tissues) so they cannot grow back.
Yes, in most cases. However, some people have medical conditions that do not allow them to sleep, and while they may experience minor hallucinations, they otherwise survive.
Carbon, nitrogen, oxygen, hydrogen, phosphorus, calcium and potassium are the main 7 elements in the human body. However sodium and a smaller amount of other elements (iron, zinc, etc.) are requrired to survive. Most other elements are found in the body in trace quantities.

Maybe instead of asking questions you should spend some of your time studying grammar as the question is not legible. It should read 'DO Human beings' eat about a pound of insects every year?' Oh and the answer - f*ck knows
Many lizards can regenerate their tails; axolotls can regenerate toes, or even internal organs. Many insects and spiders can regenerate lost limbs, but usually they have to wait until they molt (shed their exo-skeleton).
Actually, it's every four years, because a year is technically 365.25 days. They just divided it up to make it easier.

The rate of blood cell formation varies depending on the individual, but a typical production might average 200,000,000,000 red cells per day, 10,000,000,000 white cells per day, and 400,000,000,000 platelets per day.
i believe 49 I think it's 49 if it is 7 in human years, if it is seven in dog years old then it is 1 human year old.
The number for the whole world cannot be kept. But here there is an example. - The Super Bowl is a money maker, and not just for breweries or gamblers. The football championship is a big time for human trafficking, and each year, pimps will bring in their human merchandise as forced prostitutes …for the big game. This year, in what has been called the "National Day of Johns Arrests," the Cook County, IL Sherriff's Department worked with other local and federal law agencies to conduct stings during the 10-day period leading up to the Super Bowl and ending Monday night, as part of a multi-state effort to put a stop to the crime of sex trafficking. - Large sporting events, such as the Super Bowl, bring out competitiveness in all of us, including, unfortunately, pimps and sex traffickers, Cook County Sheriff Tom Dart said in the release. "In the days leading up to and including Super Bowl Sunday, my office coordinated with 19 other law enforcement agencies from around the country to send a strong message that our communities refuse to tolerate the sale of human beings for sex." - During the sting on streets, hotels, and brothels across eight states, law enforcement arrested a total of 314 of accused "johns" - the men seeking to pay for sex - and charged them with almost $475,000 in fines. The johns are the primary culprits in the rise of sex trafficking. These men do not go out and kidnap young girls and boys themselves, but they willingly pay to have sex with them. Without the johns and their cash, there would be no money to be made in the sex trade, and the horrific business would end by starvation. Soliciting sex is therefore not a harmless bit of evening fun, but perpetuates one of the most evil existing crimes against humanity. - The picture of prostitutes as poor women trying to pay the bills by turning to the street is not always accurate. Victims of sexual exploitation are often minors, naive kids who run away from home and get forced into a form of slavery as real as any in history. The average female victims are girls from 12-14-years-old, and the typical male victims are just 11-13-years-old. While a prostitute might see 10 men day, victims of sexual trafficking may be forced to see 20-35 men per day. They aren't paid. They may be purposely hooked on hard drugs and are often beaten if they try to escape or if they don't create sufficient income for their exploiters. Immigrants are also easy targets for sexual exploitation because they don't know the system and don't know who to turn to. There is also the awareness that the sexual work they are doing is illegal, and even though they are forced into it, many sex trafficking victims fear the law. - If the victims do get arrested as prostitutes, the perpetrators will often come and bail them out and continue the exploitation. Sex trafficking doesn't just take place in the inner city, either. Traffickers transport their victims into decent neighborhoods, to nice hotels, to houses. The victims may come from poverty or the upper class, from both stable and unstable homes. Sex trafficking is found from Florida to Upper Valley of New Hampshire, and from New York to Seattle. - Jacksonville (FL) Sheriff's Office detective Dave Bisplinghoff described one 15-year-old girl who had recently testified against her captor. "She's a typical 15-year-old girl. She's an A/B honor roll student," said Bisplinghoff. "Within a matter of 36 hours, she was brought into that trade in a poor neighborhood in Jacksonville and quickly introduced to crack cocaine, then the world of prostitution...She actually got away. - He drove around and found her and, basically, physically beat her and dragged her back to his vehicle," said Bisplinghoff. The girl finally escaped, but not without emotional scarring and ties in the Jacksonville underworld. The people who are held captive by sexual traffickers are manipulated by people who can psychologically and physically dominate them. They get stuck in a web they do not know how to escape. There are indications that a sex worker is trafficked, however that law enforcement look for. If the prostitutes are not free to come and go at will or cannot speak for them, if they are under the age of 18 or show signs of abuse, these are signs that there is coercion taking place and that these are victims of sexual exploitation. - Relationships between victims and their exploiters can begin as legitimate job offers, or as a boyfriend and girlfriend relationship. "It's quite amazing how sophisticated the manipulation can be," said Abby Tassel, WISE assistant director and former Dartmouth College Sexual Abuse Awareness Program coordinator. - Once someone is in the grips of this perpetration, it's hard to escape. Ahead of the Super Bowl, the Indiana state legislature passed measures to make it easier to prosecute sex traffickers, and other states are making similar efforts. Laws alone will not heal this violent social wound, however. Parents need to be aware of the dangers and pass on wisdom to their children about the potential for exploitation. Law enforcement needs to keep their eyes open for signs of trafficking. Most fundamentally, people need to stop buying sex and perpetuating the opportunities for these crimes to take place. -from the February 07, 2012 eNews issue- (MORE)
What would happen in a human body that has lost its chromosomes at the the time a cell goes to divide as they do for repair and regeneration?
A single cell that lost it's genetic material would cease functioning. A human conceptus would not survive...an entire adult human body would certainly fail systematically as the cells divided and ceased to function.

Human cells regenerate by using stem cells. Stem cells are activated by Carbon 12 and Carbon 14 molecules in our blood stream and they regenerate cells.
