Immune System
The immune system is the body's defense against infectious organisms and other invaders. Through a series of steps called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease
The main way that your skin protects you against disease is through acting much as armor does to knight. The skin creates an impermeable layer that separates your body’s internals from the disease causing bacteria and viruses outside of you. Of course, a break in the skin barrier can allow disease to make its way into the body, but as long as the skin is free of cuts or open sores, foreign invaders are unable to get in. The skin also protects you from diseases by shedding on a regular basis. Although disease causing bacteria and viruses are unable to get through the skin to infect you without help from an opening or sore, they can attach themselves to the skin. Your skin is constantly making new cells and shedding old ones. When the dead skin cells are shed off your body to make room for the new cells, the bacteria and other disease causing agents fall of with the skin cells as well, removing them from the body
Nonspecific like the skin, it designed with and acidic surface that, for the most part, repels bacteria. Specific immunity has to do with how our lymphocytes (specialized white blood cells) can remember a specific virus or bacteria, and the next time it shows up. There are two types of specific immune system responses: cellular and humoral immune responses.
T cells destroy body cells that are infected with pathogens. B cells produce proteins that inactivate pathogens that have not yet infected a body cell
A vaccination cause your body to become immune to whatever the vaccination is for. A vaccination is a shot that helps you fight off an infection or viruses, while immunity is your body fighting off your own body.
During an allergic reaction the immune system turns its defense against a substance that does
