The Basis of the Immune System

Abstract

The immune system is a collaboration of multiple cells and proteins, which each has a specific role in identifying or attacking foreign substances. These cells and proteins work together to prevent infection in the body. The immune cells and proteins do not form a single organ or tissue. Still, it is a system that is distributed throughout the body to allow for prompt responses to a foreign substance. The immune cells can travel through the bloodstream and the lymphatic vessels, which are similar to blood vessels but carry lymph rather than blood. The immune system has one primary function: to defend your body from infections to keep you alive and healthy. There are many ways your body detects pathogens and many ways to fight them off.
