,
, Air and food pass in which one of the following areas:
B - Oral Cavity
D - Epiglottis
E - Glottis
F - Trachea
G - Esophagus
Label the following five items from the diagram:
Label B- ___________
Label D- __________
Label E- __________
Label F- __________
Label G- __________
Primary bronchi, secondary bronchi, tertiary bronchi, bronchioles
From widest to narrowest, the branches of the bronchial tree are:
Hypergastrinemia leads to excess secretion of the gastrin hormone, which induces excess secretion of
hydrochloric acid in the stomach; and, the excess acid then acts as a protective mucousa layer causing
disruption that can lead to those ulcers.
Gastrin stimulates the secretions of pepsinogens and hydrochloric acid. Excess amounts would lead to
erosion of the stomach lining.
Explain why someone who has hypergastrinemia (excessive secretion of gastrin) might develop
gastric/stomach ulcers.
3. Stomach
, 4. Gallbladder
7. Jejunum
9. Appendix
10. Rectum
Look carefully at the diagram below. Label the following 5 organs of the digestive system.
To receive credit for the intestines you must label the specific region.
3: ___________
4: ___________
7: ___________
9: ___________
10: ___________
Parietal and chief cells are located in the stomach wall and they secrete gastric juices and mucous,
secrete hormones that regulate digestive activity; also, parietal cells produce HCl in the stomach; and,
chief cells secrete te enzymes pepsinogen, rennin, and gastric lipase.
The parietal cells (located in the wall of the stomach body) secrete hydrochloric acid, generating a pH of
1.3-3.5. This very acidic pH kills many of the bacteria ingested along with food. In addition, the low pH
stops the activity of salivary amylase. The secretion of hydrochloric acid is essential in the activation of
pepsin.
Chief cells: secrete pepsinogen. Pepsinogen (a pre-enzyme) is secreted by the chief cells in the stomach.
Hydrochloric acid converts the inactive pepsinogen (secreted by the chief cells) into the active enzyme
pepsin which begins the breakdown of proteins.
Note: Essay answers must clearly be in your own words.
Answer the following essay question:
Describe parietal cells and chief cells: name their location, secretions and purposes.
