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.

2 chronic diseases of the immune system?
Probably the disease most commonly recognized as a disease of the immune system is Human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS), which is known as a secondary immune deficiency disorder (secondary = caused by something acting on the body, like the HIV virus that causes AIDS, as opposed to being primary = caused by inherited genetic mutations). There are many primary immune deficiency disorders, but these are less well-known, examples are: Severe Combined Immunodeficiency (SCID) and Selective Immunoglobulin A Deficiency.
Other diseases or disorders that affect the immune system are those that cause autoimmune diseases, such as Lupus Erythematosis, Rheumatoid Arthritis, Multiple Sclerosis, and Pernicious Anemia. These cause the the immune system to get confused and attack your cells as if they are foreign invaders to try to destroy the cells.
There are also medications that can affect the immune system to depress the immune response so that people with transplanted organs do not have the immune system attacking the "foreign" organ and creating "rejection".
What is the name of the person who specializes in diagnosing and treating the immune system?
It may vary from country to county but it can be immunologist and sometimes clinical ecologist.
The specialist is actually known as an Allergist[specializes in diagnosing and treating conditions of altered immunologic reactivity, such as allergic reaction].
Antibodies are cells that are made in the body. They are involved in immunity. Any foreign invader (antigen) that enters the body will be engulfed by its corresponding antibody, if that antibody is present in the body.
What antibodies found in body fluids?
Antibody is a humminity system of our body.the antibody is stop or eat or cough antigen and cure or stop to the diasses.
All plants (including corn) contain sugar (usually glucose and fructose) to a certain extent. It is their method of storing energy for later use after producing it from photosynthesis.
True
What are alternatives to mast cell stabilizers?
I'm not sure which is the most commonly prescribed, but two mast cell stabilizers I know of are cromolyn and nedocromil.
If you get sick then get better can you get that sickness again or are you immune to it?
It depends on the sickness.
Some diseases, like mumps, measles, or chickenpox, are pretty much "one time only" diseases. You get them, your body forms antibodies against them, and then you're protected.
Other diseases, like influenza or "colds", you can get many times. Your body forms antibodies against these also so that you only get each specific strain of influenza once, but the influenza virus mutates so quickly that every year there are several new strains and your immunity to last year's versions doesn't help you much.
B cells do not contain any antibodies on their surface. Generally, B cells produce all the antibodies in the body is in need of; as instructed by T helper cells (CD4+ cells).
When the immune system fails to recognize self and destroys its own tissues what is this?
The medical term for the immune system failing to recognize its own body tissue and attacking its owner's body is autoimmunity. Common examples of autoimmune disorder are (a) Rheumatoid arthritis and (b) systemic lupus erythematosus ("lupus")
How human immunodeficiency virus (hiv) affects on the immune system?
It uses one of the main type of immune cells - CD4 cells - to reproduce. The immune response to infection is to produce more CD4 cells, which the virus uses to reproduce even more etc. The immune system initially controls the virus. However, without treatment, usually over many years, the virus slowly wears down the number of CD4 cells. This leaves someone vulnerable to a wide range of serious infections.
What happens when your immune system cannot fight off an infection?
coz some of these pathogens keeps on replicating thus reducing body's capability to sense them
What is the result when a person receives an immunization called?
Immunological memory, which is the name for when the "adaptive immune system" remembers the weakened or dead foreign molecules and uses that memory to destroy them far earlier when the real disease comes about.
How do you B cells help defend the body against pathogens?
B cells make antibodies that grab on to the antigens and make them clump together then something eats them.
What are the three important points about HIV transmission?
HIV lives in WBC's and in present in the sexual fluids of humans
HIV the simplest safeguard during sex is the proper use of a latex condom
HIV breaks down the body's immunity to infections leading to ADIS
A Macrophage is a white blood cell, produced by Monocytes. Monocytes and Macrophages are both Phagocytes. These work as a part of the human immune system. They act in non-specific "innate" immunity defense and are able to initiate specific "cell-mediated" immunity.
The role of a phagocyte is to engulf and "digest"/destroy cell debris or pathogens, such as viruses and bacteria. They are directly responsible for this process called phagocytosis. Macrophages also stimulate Lymphocytes and other immune cells that react to pathogens as what is called an "antigen-presenting" cell, also known as a histiocyte .
Macrophages are located throughout the bloodstream, and may be "fixed" or they can be freely motile and capable of amoeboid-like movement.
Why is the spleen part of the immune system?
The spleen is a purplish red organ located in the upper left part of your abdominal cavity. The spleen is an integral part of the immune system. The spleen filters blood, removes old or damaged platelets and red blood cells, stores blood, and forms some types of white blood cells. If the spleen is damaged it can be removed. You can live without your spleen, but your resistance to infection will be lowered.
Do some white blood cells surround ans swallow whole germs?
Some do and these are called macrophages. The word macrophage means big eater.
