SOLUTION FULL ANSWER KEY
⩥ Be able to label the following:
Stomach
Gallbladder
Jejunum (not small intestine)
Appendix (not large intestine)
Rectum (not large intestine. Answer:
⩥ A patient is experiencing vitamin toxicity. What type of vitamin would
be causing this
toxicity? Explain your answer.
A. Water soluble vitamin
B. Fat soluble vitamin
C. All of the above. Answer: Fat soluble vitamins are stored within the
body's fat stores making it harder for
the body to rid itself of them.
, ⩥ Explain which digestive system functions are carried out by the large
intestine.. Answer: Absorption: In the large intestine water and
electrolytes are reabsorbed and
vitamins are absorbed.
Defecation: Feces travel to the rectum where it is excreted via the anus.
⩥ Describe parietal cells and chief cells: name their location, secretions
and purposes.. Answer: 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
⩥ Match the digestive organ with the one substance it produces:
