ATI TEAS Digestive System
what are the four main functions for the digestive system? - correct answer ✔✔movement, secretion,
digestion and absorption
what is movement in the digestive system? - correct answer ✔✔movement mixes and passes nutrients
through the system and eliminates waste
what does secretion do? - correct answer ✔✔it secretes enzymes, hormones, and other substances
necessary for digestion into the digestive system
what does digestion do? - correct answer ✔✔chemically breaks down nutrients into smaller units that
enter the internal environment
what does absorption do? - correct answer ✔✔it's a passage for nutrients to go into the plasma
membranes into the blood or lymph then to the rest of the body.
what are the major nutrients broken down in the digestive system? - correct answer ✔✔proteins- help
fight infections and makes healthy cells, carbohydrates and minerals
what is the GI tract? - correct answer ✔✔long tube that begins at the mouth and ends at the anus
what are the other names for GI tract? - correct answer ✔✔digestive or alimentary tract
what are the three solid organs of the GI tract? - correct answer ✔✔liver, pancreas, and gallbladder
What are the hollow organs? - correct answer ✔✔mouth, esophagus, stomach, and intestines
What is peristalsis and where does it start? - correct answer ✔✔the involuntary constriction and
relaxation of the muscles. It starts at the esophagus.
, Where does digestion begin? - correct answer ✔✔In the mouth with the chewing and mixing of
nutrients with saliva
what does the salivary glands produce and what are the three glands? - correct answer ✔✔saliva;
parotid, sublingual, and submandibular
what does saliva do? - correct answer ✔✔it lubricates and uses enzymes to break down starch and
carbohydrates in food
how is food pushed to the pharynx? - correct answer ✔✔by the tounge
What is the epiglottis? - correct answer ✔✔a flap that flips down to cover the entry to the trachea
during swallowing
what is the function of the stomach? - correct answer ✔✔mix and store food, dissolve and degrade food

down the lower esophageal sphincter to the stomach. Heartburn occurs when the lower sphincter does
not close all the way.
Where does protein digestion begin? - correct answer ✔✔in the stomach with pepsin, which is activated
by acid and autocatalysis
what are the three main secretions of the stomach? - correct answer ✔✔*Pepsinogen* (chief cells),
*Mucus* (goblet cells), *hydrochloric acid* (parietal cells)
what are the chemically broken down food in the stomach called? - correct answer ✔✔chyme
what are the parts of the stomach? - correct answer ✔✔carida, which is close to the esophagus, fundus,
which is the upper part of the stomach, body, which is the biggest part of the stomach, the antrum,
