The digestive system breaks down food through mechanical and chemical digestion and absorbs nutrients from digested food into the bloodstream. The major organs of the digestive system include the esophagus, stomach, small and large intestines, liver, gallbladder and pancreas. Common medical terms related to the digestive system include gastrointestinal, referring to the series of hollow organs from mouth to anus, nasogastric pertaining to the nose and stomach, hepatitis B virus which is a liver infection spread through bodily fluids, fecal occult blood test which detects hidden blood in stool, and inflammatory bowel disease which causes inflammation in the digestive tract.
