Question

What is the importance of the immune system?

Answer 1

To fight disease and infection.

Answer 2

The immune system is a network of cells and organs that work together to defend the body against attacks by "foreign" invaders.

The system enables your body to know the difference between yourself, germs, and the outside world. Your body sees any illness or outside nuisance such as pollen, as a foreign substance. The body does not like foreign substances because they result in illness, pain, and other physically negative phenomena. That is why your body is set up to battle against what it perceives as an invader.

Your immune system is like a community or team. This team is comprised of many different cells that work together to keep you healthy. They all have specialized functions and ways of communicating with each other. The two important tasks of the immune system are to kill and to remember. Killing and remembering involves recognizing foreign invaders. Nature is teeming with invaders ready to infect our bodies. Thus, our immune system is equipped to specifically recognize the differences between different invaders referred to as pathogens. All pathogens release certain chemicals and proteins that our immune defense recognizes. Recognition triggers a kill response. The cells responsible for killing actually eat and digest the pathogen. Eating the pathogen allows some of the killer cells to process the bad guys and package them so that the other members of the immune team and recognize them if the same invaders return.
