What high school courses are needed to become a cardiovascular surgeon?
To prepare yourslef for the intense competition you will experience in one of the toughest disciplines in the field of medicine, you should test your mettle now in the toughest course your high school has to offer. That means taking as many first-track, honors, and AP courses as you can possibly handle. Ace those and with decent SATs or ACTs, you should be able to get into a top-drawer college. Assuming you do well in college, you will hopefully get into a top medical school, where you'll fight it out with other top guns who want to be surgeons. Good luck and God bless you.
What does it mean when your heart beats 3 times really fast out of nowhere?
Your either exercising, or your heart rates rising, you've got to be working out.
What are some decomposers in the Taiga?
The Taiga region has a subarctic climate. Invertebrates in this area include: beterotrophic bacteria, Pleurozium Schreberi, Calothrix, Testate Amoebae and Ixodes Persulcatus.
It is in my understanding that hyperventilating or in milder forms - panting, is the method in which dogs cool off. Therefore it is not a problem unless they can not seem to get relief and continue hyperventilating indefinitely, in which case you need to contact a reputable veterinarian.
How many times does the average baby's heart beat per minute?
I think the average is around 120-160 beats per minute. average is around 140
How many times a human heart beats in a minute?
It varies depending on your age and the level of activity being undertaken, your heart will obviously beat faster if you are doing something strenuos than it would do if you were relaxing reading a book.
What is the elephant's heart rate?
28 beats per minute at rest (see www.thaifocus.com/elephant/heartbeat.htm)
How many times does a 'frogs' heart beat in one minute?
A frog's heart rate can be anywhere from 40 to 50 beats per minute.
If a heart beats 72 times per minute how many times would it beat in 75 years?
you do, 72 x 60= 4,320 (for minutes in an hour) 4,320 x 24 =103,680 (for hours in the day) 103,680 x 365 = 37,843,200 for days in the year, then multiply that by 75 = 2838240000 x
Your dog has bad hips what can you give to help her joint problems?
What you can do is keep the dog out of the cold, no laying on cold hard surfaces, go to the vet for evaluation and no doubt the vet will give you some pain meds so the dog can get around more easily and get a little exercise.
How many breaths per minute do chickens have?
At rest and not under stress a male chicken (rooster) has a rate of between 12 and 20 breaths per minute. The hens rate is higher under the same conditions averaging 20 to 36 breaths per minute.
Many factors can influence these rates including ambient temperatures, stress and activity.
the recommended amount of Noni juice to consume varies for the person. if you are taking the original Noni juice the recommended dosage is 30ml two times daily.
it really depends more on your body and needs though. i know many who take 120ml throughout the day. this seems to be good for ones who are older and need an energy boost or ones who have actual health problems that they are treating.

Does chewing tobacco raise your heart rate?
Yes, and although I'm a smoker (trying to quit) and many people find it a disgusting habit I find chewing tobacco is worse. Also by chewing tobacco your heart rate just doesn't go up, but it discolors your teeth (worse than smoking) and if you have a mustache or beard it can leave an ugly amber stain and smell terrible. Chewing tobacco has a higher risk of mouth, tongue and throat cancer.
I am looking at the above answer and wonder where the research is on chewing tobacco raising the heart rate worse than smoking. I use chewing tobacco and work at a dentist office. We have seen no oral cancer in chewing tobacco users in the 6 years I have been there. Proper oral care can keep teeth white. Chewing tobacco IS NOT SAFE. Compared to smoking however, the long term health effects appear significantly lower.
I work for doctors (not dentists) and even in medical books it will tell you that if a tobacco user you should see your dentist on a regular basis so the dentist can not only keep your teeth and gums in good shape, but they also check inside the mouth (including the tongue) for cancer. My dentist concurs. This is the article where I got my information (note ... Mayo clinic.) There are no copyright laws on this article: Science News After snuff use, heart rate increased by about 15 beats per minute (25 percent), systolic blood pressure went up by 12 mmHg (10 percent), and measurements of adrenalin in the bloodstream increased by more than 50 percent. "These results suggest a very significant excitatory effect of substances contained in spit tobacco on the part of the nervous system regulating the heart and blood vessels," says Virend Somers, M.D., Ph.D., the Mayo Clinic cardiologist who led the study. "Although we did anticipate some increase in blood pressure, we were surprised at the magnitude of the increase, as well as the very striking increases in heart rate and plasma epinephrine, or adrenalin. We anticipated that since these individuals were young and healthy and were accustomed to using spit tobacco, that any responses that we measured would be blunted. This makes the degree of increases even more noteworthy." Robert Wolk, M.D., Ph.D., lead author on this study, noted that these results have implications both for long-term users and for individuals with established heart disease. "The degree of speeding up of heart rate and increase in blood pressure, as well the increase in adrenalin (epinephrine) levels, suggest that if similar changes occur in people with established heart disease, who use spit tobacco, there may be reason to expect adverse consequences," Dr. Wolk says. "Dipping" is Rising More than five million adults - and more than 750,000 adolescents - use smokeless tobacco in the United States. Snuff use is increasing, especially in young males who participate in athletics. Its cardiovascular effects are not as clear or well understood as those of cigarettes, partly because fewer studies have been done, and partly because many spit tobacco users are relatively young and the bad effects may not be apparent unless use continues for prolonged periods. Blunting a Protective Mechanism By placing electrodes into the sympathetic nerves of the participants, the researchers also obtained a window on the message from the brain to the blood vessels on a moment-by-moment basis. Normally, when blood pressure is increased by an external substance, the body seeks to protect the cardiovascular system by decreasing heart rate and dilating the blood vessels. It does this by "shutting down" the sympathetic nervous system, so that heart rate is slower, and the widening of blood vessels starts to bring blood pressure down. The researchers demonstrated this by giving another group of subjects an intravenous medication, phenylephrine, to raise blood pressure about as much as they saw when spit tobacco was used. In response, those subjects' heart rates decreased by more than 10 beats a minute and the activity of the sympathetic nervous system went down to very low levels. "This is an example of how the body tries to protect itself from the higher blood pressures," Dr. Somers explains. "However, when the blood pressure is raised by spit tobacco, the heart rate actually speeds up dramatically and there is no decrease in the sympathetic nervous system activity. This tells us that the normal protective mechanisms which help dampen down spikes in blood pressure are blunted when using spit tobacco. "Spit tobacco is a very potent cause of acute increases in blood pressure, heart rate, and adrenalin levels," Dr. Somers concludes. "Since many athletes, who are already under a fair amount of stress in competitive situations, also use spit tobacco, the blood pressure and heart rate increases need to be recognized and understood. And since spit tobacco not only raises blood pressure but also blunts the body's normal defense response to blood pressure increases, long-term dipping would seem likely to increase the risk of cardiovascular disease." ### Other authors on the study include: Abu S. M. Shamsuzzaman, MBBS, Ph.D., Anna Svatikova, BA, Christina Huyber, Corey Huck, BA, Krzysztof Narkiewicz, M.D., Ph.D. Adapted from materials provided by Mayo Clinic.
What does it mean when hamsters blood from their bottoms?
This could be for several reasons. Internal bleeding is one of the scarier ones. If it's a female, cysts could also be the problem. In any case, take it to a vet immedietly. Your pet's life could possibly be at stake.
Does cigarettes lower blood pressure?
I believe so. It also can gradually degrade your lungs. If a smoker gets a cat scan, you can see a black thick substance gathering up in the lungs. This can gradually shorten your life span, and you are more prone to sickness and other diseases.
Can eating cornstarch give you clogged arteries?
No. Clogged arteries are caused by too much 'bad' cholesterol and triglycerides in your blood...nothing to do with cornstarch.

What nutrients does sweet corn contain?
Corn contains Vitamin B1 (thiamine, Folate, Vitamin C, Phosphorus, Vitamin B5 (pantothenic acid, Vitamin A (more in the yellow corn), Manganese, and several antioxidants including ferulic acid and phenolics. It depends on what kind of corn and how it is prepared, but for the most part corn offers carbohydrates, potassium, protein, and fiber. Apparently, an average sized ear of corn has approximately 75 calories and only 1 gram of fat (before people smother it in butter and salt, etc). Corn also provides many vitamins, such as B1, B5, vitamin C, and other nutrients including folate, phosporous, and manganese.
Are oysters high in cholesterol?
Previously oysters were thought to contain high amounts of cholesterol but now, since new methods of calculating cholesterol levels are more accurate, oysters have been removed from the restricted list. Oysters are naturally low in fat, sodium, and calories. They are also a very good source of high quality protein, polyunsaturated fatty acids, and iron. A three ounce cooked portion of oysters contains only 93 milligrams of cholesterol
Oysters are not only delicious, but they're also one of the most nutritionally well balanced of foods, containing protein, carbohydrates and lipids. The National Heart and Lung Institute suggest oysters as an ideal food for inclusion in low-cholesterol diets. Oysters are an excellent source of vitamins A, B1(thiamin), B2 (riboflavin), B3 (niacin), C (ascorbic acid) and D (calciferol). Four or five medium size oysters supply the recommended daily allowance of iron, copper, iodine, magnesium, calcium, zinc, manganese and phosphorus.
How much fat in a baked potato?
There is zero saturated fat in a baked potato. However if you add butter or sour cream, you add saturated fat. Most saturated fats are from animal products is an easy way to remember which fats are saturated.
What makes brown chicken eggs healthier for human consumption than white chicken eggs?
Nope! The only difference between brown eggs & white eggs is the shell's colour. Happy Egg Eating! Absolutely NOT! The only difference in shell color is the breed of chicken that laid it. If the hens were fed the same diet, brown-shelled eggs and white-shelled eggs are the same. Thete ARE some people who swear that they taste differently. Unfortunately for them, taste tests have consistently proved that those people CANNOT tell the difference.
How many carcinogens are in smokeless tobacco?
There are currently 69 known carcinogens in a single puff of cigarette smoke. Go D.A.R.E.!
The IARC, part of the World Health Organisation, lists nearly 1,000 carcinogens. The vast majority of these are in the (smoke-free) 'fresh air' we breathe, the food we eat, the water we drink, the prescription drugs we take, are produced endogenously by the human body, are present in the personal hygiene and cosmetic products we use and the products we clean our houses with.........
What are the uses of alcoholic beverages?
Drinking (within reason) can be good for socializing, by lowering inhibitions and making it easier to relax in social situations. It is recommended that people limit themselves to two drinks a day (2 shots, beers or 5-oz. servings of wine) for men, and one for women, who do not produce as much of the enzyme that metabolizes alcohol.
