Question: How does the immune system work in response 2 bacterial infection!?
Answers:
To understand the immune system try looking at a something that has died this will tell you alot of the immune system right there!.This is where the immune system will be shut completely down for good!. In a matter of hours the body is invaded by all sorts of bacteria,microbes, and parasites!. None of this is allowed while the immune system is working and fairly strong!.
When a virus or bacteria (AKA a germ) invades a body and reproduces it normally causes problems, this also causes some effects makes a person sick!.Strep throat bacteria (streptococcus) releases a toxin that causes inflammation in the throat!. Polio virus releases toxins that destroy nerve cells!. Some bacterial are good for the body this will be in the intestines for digesting foods!. Many are harmful if gets into body or bloodstreams Viral and bacterial infections are the most common cause of illness for most people, this causes colds, infuenza,measles, mumps, malaria, AIDS and others as well!.
The job of the immune system is to protect the human body from infections this is done in 3 diffrent ways!.
1) It creates a barrier that prevents bacteria and viruses from entering the body!.
2) If either do enter the body the immune system tries to detect and eliminate it before it can make a home and reproduce!.
3) If this does get in and takes hold the immune system is in charge of eliminating it!.
4) Your body (as well as others) is a multi-cellular organism made up of perhapes 100 trillion cells
The cells are complicated manchines, each one has a nucleus engery production equipment!. Bacteria are single-celled organisms that are much simpler!. They have no nucleus they are perhapes 1/100th the size of a human cell and might measure 1 micrometer long!. Bacteria are completely independent organisms able to eat and reproduce!. This will reproduce in 20-30 minutes and does this very fast while it spreads threw a body!.
Antibodies this responds to bacteria, viruses, toxins, called antigens!. Clsaa:: A,IgA,IgD,IgE,IgG,IgM!. If germs enter threw physical or chemical barriers into bloodstream a mixture of fluid proteins called complement is activated and attacks them!.
Hormones are made by immune system some also suppress the immune system as well
Interleukins are another type hormone made by white blood cells these kill bacteria ( many types)!.
Lymph nodes are basically filters that trap germs and other foreign bodies lymphocytes are a type white cell blood cell which neutralizes or distroys germs!. The spleen filters the blood for foreign cells also looks for old red blood cells that need replaced White blood cells are the main cells in a human body and most imporant for all of us and the immune system!.
There are many cells in the body to help distroy or slow down bacteria and viruses, Some are calledLeukocytes,Lymphocyte, Monocytes, Gianulocytes, B- cells, Plasma cells, T cells, Helper T -cells, Killer T- cells, Suppressor T- cells, Natural Killer cells, Neuliophils, Eosinophils, Basophils, Phagoctes, Macrophages,
T- cells do most of the fighting
B-cells are like tiny antibodies there are thousands of diffrent B-cells in the blood at any time each armed with antibodies against a particular germ!. Then when a certain germs come into contact with a B- cell and this germ is not right and B-cell dislikes The B-cell will multiply dramatically and release the right amounts of antibodies for this germ
T-cells work diffrent since many germs hide inside cells such as viruses and parasites its the T- cels job to identify and distroy!. Two types for this job, "killer and helper"!. Helper cells identify and send message to killer cells which find and distroy An invaded cell gives its self away with adnormal proteins on its surface, helper cells encounter abnormal proteins they send out chemicals called lymphokines that tell killer cells to multiply killer cells lock on to abnormal cells and distroy it!. Like B -cells some stick around ready to attack any more abnormal cells they come in contact with!.!.Www@Answer-Health@Com
