UTA A&P II EXAM 3 STUDY QUESTIONS WITH
CORRECT ANSWERS
Peristalsis - Correct Answer the involuntary constriction and relaxation of the muscles of the intestine
or another canal, creating wavelike movements that push the contents of the canal forward.
uvula - Correct Answer small projection hanging from the back middle edge of the soft palate
mesenteries - Correct Answer connective tissue sheets that loosely suspend the stomach and
intestines from the abdominal wall.
provide access route for blood vessels, nerves, and lymphatic vessels to and from digestive tract
pylorus - Correct Answer portion of the stomach that connects to the small intestine
greater omentum - Correct Answer part of the peritoneum attached to the stomach and to the colon
and covering the intestines
plicae circulares - Correct Answer folds of the small intestine wall
pairs of salivary glands - Correct Answer parotid (produce amylase), sublingual (produce mucus),
submandibular(secrete buffers, glycoproteins and salivary amylase)
Which salivary gland secretes a watery mixture rich in salivary amylase and bicarbonate ion? -
Correct Answer parotid
Functions of the digestive system - Correct Answer secretion, absorption, digestion (chemical and
mechanical), ingestion, and excretion
Layers of the intestinal wall - Correct Answer 1. Mucosa--epithelium and lamina propia of areolar
tissue
2. Submucosal layer--irregular connective tissue
3. Muscularis externa--smooth muscle
4. Serosa (or adventitia if retroperitoneal) --serous membrane
, What is between the layer of circular and longitudinal muscle in the muscularis externa? - Correct
Answer myenteric plexus
What layer are the sensory nerve cells, parasympathetic ganglia, and sympathetic postganglionic
fibers? - Correct Answer submucosa in submucosal plexus
What layer alters the shape of the intestinal lumen and moves epithelial pleats and folds? - Correct
Answer muscularis mucosae
Which layer contains the lamina propria and mucous epithelium? - Correct Answer mucosa
Which layer are large blood vessels and lymphatics are found in? - Correct Answer submucosa
What is the function of pepsin? - Correct Answer protein digestion
where is pepsin secreted? - Correct Answer pepsinogen is secreted by chief cells. pepsinogen is later
converted to pepsin in the stomach due to the highly acidic environment
what part of the stomach connects to the duodenum? - Correct Answer pylorus
which part of the stomach connects to the esophagus? - Correct Answer cardia
What are the the prominent ridges in the lining of the empty stomach? - Correct Answer ruggae
function of chief cells - Correct Answer secrete pepsinogen
Function of G cells - Correct Answer secrete gastrin
function of gastrin - Correct Answer stimulate parietal cells to secrete HCL.
stimulates contractions of gastric walls
