Digestive System

The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

Fly

Flies are thought to carry disease by transporting infectious agents on their feet. They may spread polio, hepatitis A, Entameba histalytica, typhoid, and other diseases. (Courtesy of the Centers for Disease Control.)

Hepatitis A

A fly may act as a mechanical vector of diseases such as Hepatitis A, which means the fly carries the infective organism on its feet or mouth parts and contaminates food or water which a person then consumes. A biological vector actually develops an infective organism in its body and passes it along to its host, usually through its saliva. A fly can be a biological vector, as in the transmission of leishmaniasis by the sandfly.
