Immune System
This category is for questions about how our bodies identify and fight off disease, infection or pathogens through specialized cells, tissues and organs. The system that does this is called the immune system. It produces antibodies which recognize intruders and neutralizes potentially pathogenic organisms or substances.

How does the immune system remember the previous infections?
For survival reasons or otherwise, the immune system would save a "file" of certain intruders and threats based on traits and characteristics. The protein, called Lck, is what "teaches" T-cells (white blood cells that attack viruses and other threats) to identify the characteristics of pathogens, whether clearly or vaguely identified within the body. As a result, Lck helps prevent the body's immune system from being constantly weighed down by a "biological hard drive" remembering all cell and invader statuses.
Can you donate blood with hypothyroidism?
If you wanna know then donate blood to a person ; they will have you fill out papers. If they find something in your blood that they don't want to give to the other person that they are donating it too then they will not use it. They always check the blood before they give it to the person.
NAILS GROW FROM MANY THINGS INCLUDING THE SUN, NUTRIENTS FROM THE THINGS ALL AROUND U AND MANY MORE THINGS. HA!!! Nice answer I happen to be an expert on nails and not just painting them. Well your nails grow from protein. They also grow like your skin because that's what they are a modified type of skin. When your old nail cells die. Your new ones push them out of the way. Your old ones create a protein for your new ones causing them to grow 2 mm per month. To keep them healthy you should use lots of moisturizer. With your toenails cut them straight across. Not curved otherwise it will cause an ingrowth that pierces your skin. Your fingernails can be cut curved but it's better to do them straight across. Yes I know this answer is way better than the other one.
What are the organs involved with the immune system?
Lymph nodes, lymphatic vessels, Peyer's patch, spleen, thymus, and tonsils are the organs in the immune system.
Specifically, lymph nodes contain lymphocytes (white blood cells) which fight infection. Lymphatic vessels have fluid which circulates and detects the presence of a foreign micro-organism's cells. Peyer's patch in the appendix and small intestine as well as the tonsils at the back of the throat operate as the body's first line of lymphocyte-conducted defense against infection. The spleen operates to detect antigens and produce antibodies. The thymus gland in the upper chest produces many lymphocytes during a person's childhood.
How does the immune system function?
The immune system works in three ways: external, passive non-specific response: natural flora (eg- bacterium on skin), secretions (eg- mucus which prevents harmful bacteria contacting cell wall), surface barriers (eg-skin) internal, active non-specific response: White blood cells such as phagocytes and macrophages, complement proteins and interferons internal, active specific response: B lymphocytes, T lymphocytes
No, you will not have a more likely chance to fight off an STD if you have a high immune system. STD\'s are bacterial infections and the human immune system is not equipped to deal with these alone. Bacterial infections sometimes require antibiotics to clear them.
It means that your body is used to something and it doesn't have an effect on you. For example, a lot of people get addicted to pills because they keep taking them and eventually they stop working because their bodies are used to them so they have to either take more or pills that are stronger.
How does fever protect the body from pathogens?
The difference in temperature will make the immune system fight more effectively and the infection will weaken. Also, the body's temperature's increase itself can actually destroy the cause of the illness, such as infection.
Yes, by your body raising its temperature it helps to destroy infections that can not survive in the higher temperature.
True. It also disrupts the ability for viruses to multiply, as they normally thrive at body temperature. It can also aid the body's immune system to identify an infenction and raise an army of white blood cells against it.What can cause a burning tongue and what can treat it?
There is actually a condition called burning tongue syndrome. There are different causes, and although it can affect men, it is mainly a symptom of menopause. It may affect up to 40% of menopausal women. It is usually caused by low levels of estrogen.
Other causes may include low amounts of B12, Iron, Niacin, acid reflux, oral yeast, or diabetes. A quick temporary remedy is to chew some sugar free gum. If the symptoms continue, you really do need to see a doctor to find out the cause.
What is the clumping together of RBCs by antibodies?
coagulation- is not the correct answer!
The correct answer from my "Anatomy and Physiology" book is Agglutination
How do you correct splitting finger nails?
Cracking, splitting nails typically result from repeated exposure to water over long periods of time. Baths, showers, dish-washing and swimming can all break down the cells that hold your nails together, and so does frequent use of nail polish and nail polish remover!!
Before you do anything with those cracked nails, you need to gently clip excess parts that could catch on something and cause tears that go deeper into the nail bed. Then you need to figure out what's making your nails crack and split.
You need to keep your nails moisturized.
Moisturizing your nails is simple. Whenever you use hand lotion or moisturizer, just take an extra moment to rub it in and around your nails. You should use moisturizer after washing your hands, taking a bath, doing dishes or using nail polish remover. If you forget during the day, apply a small amount of moisturizer to your nails and cuticles before you go to bed at night. This simple step will go a long way toward healing your damaged nails. Look for moisturizers that contain the following ingredients: proteins, such as collagen and keratin, strengthen cells in the nail plate, making the nail more resistant to splitting and cracking.
- Occlusives, such as petrolatum, lanolin and mineral oil, slow the rate of moisture loss from your nails, preventing dryness.
- Humectants trap moisture in the nail plate to prevent drying and cracking. Common humectants include urea, lactic acid, glycerin, propylene glycol, alpha hydroxy acids and phospholipids
- Watch the water. If you expose your nails to a lot of water over the course of the day, you may want to invest in a pair of cotton-lined rubber gloves or disposable plastic gloves. You should especially consider wearing gloves when washing dishes or cleaning with chemicals.
- Go easy on the chemicals. Harsh soaps and chemicals can dry out your nails, making them split and crack. If you use a lot of chemicals and soaps, be sure to wear those gloves while doing so.
- Switch it up. You can't avoid soap all the time, so you may want to use a different soap. Mild soaps that contain moisturizers are gentler not only on your nails, but also on your hands.
- Limit the remover. Nail polish remover, especially varieties that contain acetone, can be drying to fingernails. Try not to use nail polish remover more than once every other week and look for removers that don't contain acetone.
- Trim your nails. Nails that are ragged and chipped are more likely to catch and split. Keep fingernails short, cut straight cut across the top, and gently file the sides to a rounded shape. This should be it! I hope I helped you!
According to the chart that came with the blood information about my current blood test, albumin is 4.1 and ALT (SGOT is 49). What does this mean? Janet
What does it mean if the lymphocyte count is above normal range?
You may have a viral infection, bacterial infection or if very high-leukemia.
There are many factors that can cause high lymphocyte count. This can be caused by an infection, autoimmune disorder and cancer of the blood among so many others.
What are monospecific Polyclonal Antibodies?
Monospecific Polyclonal antibodies are produced by not just a common germ cell like monoclonal antibodies, but from other products. Monospecific antibodies have affinity for the same antigen.
What is the antigen-antibody response as it relates to blood groups?
Antigens, the specific sugars and proteins found on the red cell membrane, are what determine the phenotype of each blood group or system. The presence or absence of each antigen is determined by genes inherited from each parent. Besides the ABO system, there are at least 30 additional blood groups that are important in transfusion medicine.
Could a virus cause you to have small blisters underneath your tongue?
Yes. A flu-like virus can certainly cause this. Stomach upsets can cause this. Ph levels that are off. Also it could be from too much acidity in the body. If one were to eat a pound of beautiful juicy tomatoes they are more than likely to have a very sore mouth and that includes under the tongue. If it continues for 4 - 5 days it's best to have your doctor have a look. Rinse your mouth out 3 - 4 times a day (especially before going to bed) with warm salted water. Gargle (getting it under the tongue) spit out BUT DON'T RINSE YOUR MOUTH OUT! You should also brush your teeth after every meal.
An antigen is an antibody generator which is introduced to the body to provoke a reaction. When appropriate an autoantigen is introduced for specific autoimmune issues.
Does marijuana affect your immune system?
It's not really an immunity, rather a tolerance to marijuana. Like alot of other drugs the more you take it, the more your body gets used to it. People who consume marijuana on a regular basis find that after a few months they don't get as affected or as stoned as they did whey they started and so they have to take more. It's alot to do with your body's immune system. If you get a virus or a cold, you're immune system fights it and gets over it, if you acquire that same virus or cold again you will get less sick or not sick at all because your immune system knows how to fight it. However, if you get the same virus or cold a year later you will definitely have no immunity or tolerance to it at all. So that's why people who consume marijuana try to go without marijuana for a month or two so that they can lower their tolerance to the drug.
What does low lymphocyte count mean?
Where there is a low level of lymphocytes, it could be because the body doesn't make enough lymphocytes or the lymphocytes get stuck in the lymph nodes or spleen. Infectious diseases, steroid therapy or chemotherapy can also cause the lower levels.
What happens if a person is given the wrong blood during transfusion?
It's most likely that the person would die because their body would reject the blood, and it would be just as effective as filling the person with water.
What are special protein that attaches to a specific pathogen?
Antibodies (also known as immunoglobulins, abbreviated Ig) are gamma globulin proteinsthat are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses..
What helps immune system recognize germs and reject them?
The body system that recognizes germs and "rejects" them is the immune system. There are many components to the immune system. Some components are specialized to recognize fungal invaders, some are specialized to recognize viral invaders, and others are specialized to recognize bacterial invaders. In general, the cells responsible for recognizing and destroying invaders are white blood cells.
