An introduction to what can “go wrong” with each organ system
When the human body is not working properly we say that someone has a disease. Sometimes a disease is caused by a bacteria, virus, fungus, or animal that has taken up residence within our bodies, these are usually thought of as "infectious" diseases. When we are sick the body is trying to fight off the invader. Some diseases and conditions are not fully understood as to how or why they originate, and may have multiple factors; these can range from bedwetting or migraines to diabetes or cancer. Other diseases are passed on in families, these are called genetic diseases or genetic disorders. Diseases disrupt normal body functioning (homeostasis), causing the breakdown of one or more body systems. Physical injuries include breaks, sprains, etc also disrupt normal body functioning.
