HUMAN DISEASE AND HEALTH The human body is an amazing machine. Has the ability to repair itself, to fight off attacking microorganisms and adapt to a variety of situations.

Often time microorganisms enter the body and attempt to infect the body causing a disease.
A disease is a condition where an organism experiences impaired function often with detrimental symptoms.
