BIOS 252 ANATOMY AND PHYSIOLOGY STUDY
GUIDE WITH QUESTIONS AND ANSWERS.
UPDATED FOR 2024/2025
1 . What is the first line of defense against changes in blood
pH?: Buffering of hydrogen ions
2. The activity of the respiratory system can compensate for an
acidosis
(decrease in pH) by: hyperventilation induced decrease in C02 in the
body
3. How might a high fat diet cause metabolic acidosis: due to
the breakdown of fat into fatty acids which are acids
4. Which of the following acts as a buffer to minimize changes
in intracellular pH? : phosphate and proteins
5. Which of the following is NOT a basic process of the
digestive system? : filtration
6. As the food is broken into smaller pieces in the mouth, it is
combined with the enzyme in the saliva that facilitates
the digestion of any starch in to the food: amylase
7. What cells secrete pepsinogen into the lumen of the
stomach: chief 8. What type of cell secretes both gastric acid and
intrinsic factor into the lumen of the stomach? : parietal cells
9. What protects the stomach wall from the acidic luminal
contents?: the gastric mucosal barrier
10. What is the primary function of the colon?: reabsorb water to
reduce the volume of the fecal matter
1 1. Which of the following is not one of the digestive enzyme
secreted by the exocrine pancreas? : maltase
12. What enzyme, secreted by the exocrine pancreas, digests
fats?: lipase 13. Proteins are digested by which of the following
enzymes?: pepsin and trypsin
1/4
