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.

What are 2 indirect ways to catch a pathogen?
Two indirect ways to catch a pathogen include touching surfaces contaminated with germs, such as doorknobs or shared equipment, and inhaling respiratory droplets that linger in the air after an infected person coughs or sneezes. Additionally, consuming food or water that has been contaminated by pathogens can also lead to infection. Practicing good hygiene, such as frequent handwashing and sanitizing surfaces, can help reduce these risks.
How does being too clean weaken the immune system?
Your immune system cant produce antibodies for infections/viruses if it is not exposed to them.
There are two types of cell that play roles in adaptive immunity. Memory T and memory B cells. These cells are produced in vast numbers when a person's immune system is activated, and these cells float around the blood and lymphatic system for months (and even years!) after the primary infection. When person is exposed to secondary infection, the immune system 'recognises' the pathogenic particles and has a heightened response to the infection.

What are the functions and property of lymphocytes?

What happens to the antibody levels when vacniated?
Vaccination introduces foreign antigen and the body responds by producing antibodies for that specific antigen. So overall levels of antibody may not considerably increase, but antibodies specific for that antigen will increase dramatically.
What is the term also known as hypersensitivity?
Hypersensitivity (also called hypersensitivity reaction) refers to undesirable reactions produced by the normal immune system, including allergies and autoimmunity. These reactions may be damaging, uncomfortable, or occasionally fatal. Hypersensitivity reactions require a pre-sensitized (immune) state of the host. The four-group classification was expounded by P. H. G. Gell and Robin Coombs in 1963. (Wikipedia)

Does meiosis occur when the immune system produces B and T cells?
B and T cells are both types of white blood cells. When the immune system produces them it is actually mitosis that occurs rather than meiosis. The are produced within the bone marrow.
How many types of abscesses are there?
two types of abscesses, septic and sterile. Most abscesses are septic, which means that they are the result of an infection. Septic abscesses can occur anywhere in the body. Only a germ and the body's immune response are required
