Functions of Digestive Tract
-breaks own food physically and chemically
-prepares food for absorption by cells of the body
-eliminates waste substances
Oral Cavity Function
Mastication - mechanical process of chewing
Saliva - chemical breakdown
Pharynx and Esophagus Function
Tongue pushes bolus (rounded mass of chewed food) down to stomach (swallowing = deglutition) (peristalsis - rhythmic contractions of smooth muscle to produce movement)
Stomach Function
Mechanical breakdown - stomach contractions
Chemical breakdown (HCI and enzyme)
Small Intestines Function
Additional enzymes and secretions further digest
Nutrient absorbed by the bloodstream
Large Intestine Function
No digestion - water absorption and removal of undigested material
Liver Function
Produces biles (fat digestion) blood sugar role
Pancreas Function
Secretes insulin and digestive enzymes to small intestines
Gallbladder
Stores and releases bile(from liver) into ducts of small intestine
Bilirubin
Orange - yellow pigment formed during destruction of erythrocytes that is taken up by liver cells and eventually excreted in the feces
Liver damage or disease
Elevated bilirubin in the blood produces yellowing of the skin (jaundice0. It can also indicate…
Bolus
