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 is The status of the immune system in someone with HIV infection can be monitored by checking?
checking antibody levels
What are the 2 types of your immune system?
Innate - cell-mediated immunity, rapid responses (because cells see bad guys and just shoot them), generally consistent over an individual's life time, regardless of pathogenic exposures. Usually works based on your cells recognising general "toll-like receptors", which is just another way of saying that they see a name tag saying "bad guy", but it doesn't say many details, like "bank robber" or "assasin", so your body deals with them but is less equipped to deal with them compared to the adaptive response.
Adaptive - antibody-mediated, slow responses (because cells see bad guys and have to run off to tell their supervisors, who then have to fill in paperwork before just setting up orange cones all around the bad guys, indicating to other cells that YES, there IS in fact a bad guy there). Very specific - one antibody for one specific receptor (every cell has hundreds, at least), and they only stick to that one, flagging it for destruction by the same cells that would have otherwise obliterated it anyway. But neon signs are always helpful for making things noticed. Anyway, the adaptive immune system changes as you come into contact with more pathogens, because your body makes antibody-producing cells, and they hang around so if you see that pathogen again, they can skip some of the paperwork and speed up the process.
How do your ears help keep pathogens out of your body?
through antibodies and certain blood vessels ears are the #1 defense
What are antigens and antibodies?
antigen-
- a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
Antibodies-
- a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
What do antibodies to the aids virus indicate?
Antibodies to the AIDS virus indicates the person is HIV positive.
Is a spleen size of 556 normal?
For humans the average size is 1"x 3"x 5". Assuming that your "556" means '5x5x6', that size indicates that its owner may be suffering from one of the many diseases or infections that cause the spleen to enlarge.
What can cause high eosinophil and monocyte count?
usually if you have some sort of an allergey to something
Why is suppressing the immune system unadvisable in patients with type I diabetes?
People with type I diabetes are already at risk for autoimmune problems, are more prone to infections, and have a complicated medical history that makes suppressing the immune system unadvisable.
What Is the difference between antigen binding site and paratope?
Antigen binding site or epitope is a part of an antigen that is recognized by the antibody.
Paratope is a part of an antibody that binds on epitope.
What is involved in the programming of T lymphocytes?
The Thymus is involved in the maturation of T Lymphocytes.
Use the "What if?" Strategy in defensive driving and persistently use your mirrors to keep alert and be prepared to spot hazards.
What is the main function of B lymphocytes?
IMPORTANCE OF B LYMPHOCYTES:
1.b lymphocytes play important role in humeral immune response.
2.they secretes antibodies.
3.they differentiate into memory and plasma cells.
AIDS
How does the immune system respond to chemicals on the surface of an invading organism?
By presenting small pieces of the organism on their surface
Discuss why gamma globulin injections are painful?
Gamma globulin is a huge injection with a long, thick needle deep in the buttock muscle that can take several minutes to administer, consequently it hurts when getting it but it doesn't produce much tenderness later.
What is one type of white blood cell that participates in the specific immune response called?
the answer is macrophages
antigen
How do antibodies interact with viruses?
yes anitbodies can destroy viruses but you have to have painkillers to destory them...make sure you don't get too addicted to them otherwise they're will be lots of viruses coming and you will become more ill..!!
Antibodies are produced by the immune system to fight the infection. If the antibodies are present in the blood, then you know you have the particular infection.
