Chapter 5 Flashcards
Gastrointestinal tract
Begins at the mouth, where the food enters, and ends with the anus, where solid waste material leaves the body.
Gastrointestinal Tract FOUR Functions
Ingestion, Digestion, Absorption, and Elimination
Ingestion
Complex food material taken into the mouth.
Digested
Broken down, mechanically and chemically, as it travels through the gastrointestinal tract.
Absorption
Nutrients from digested food pass through the lining cells or epithelium of the small intestine and into the bloodstream.
Elimination
The solid waste material that cannot be absorbed into the bloodstream leaves the blood.
Mastication
Chewing
Deglutition
Swallowing
Labial
Front surface of tooth
Peristatis
Involuntary, progressive, rhythmic contraction of muscles in the wall of the esophagus (and other gastrointestinal organs) propelling a bolus (mass of food) down toward the stomach.
Bolus
Mass of food
Pyloric sphincter
Allows food to leave the stomach and enter the small intestine when it is ready.
