The Immune System

Abstract

Human beings are constantly covered in commensal bacteria that’s total cell count outnumbers that of our own body cells. These commensal bacteria have evolved alongside humans to become both dependent on us and nonpathogenic, but what about the countless bacteria and viruses in the world that haven’t evolved alongside humans, but rather at a quicker rate? These pathogenic bacteria rely on inefficient immune systems.The immune system is made up of numerous cells that work together to protect the body from foreign pathogens. Essentially keeping the host body healthy and unharmed. Immunity is divided into to categories that act on these pathogens in different ways in order to eradicate them from the body and help keep the sickness from happening again.
