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.

Giardiasis

Giardiasis is an intestinal infection caused by a protozoan and is spread by contaminated water or contact with an infected person. People who are travelling or hiking should assume water sources are contaminated and either purify drinking water or drink bottled water. Healthcare or daycare workers should practice good hygiene when going from person to person. Unprotected anal sex can also transmit Giardiasis from an infected person to the partner.

Institutional Hygiene

Workers in daycare centers or institutions such as hospitals and eldercare should use good handwashing and hygenic techniques when going from child to child or patient to patient.

Digestive System Organs

The digestive system organs in the abdominal cavity include the liver, gallbladder, stomach, small intestine and large intestine.
