Question

22. Which of the following is not a direct result of increasing Angiotensin II release?

A) Increased Na+ reabsorption

B) Increased constriction of systemic arterioles

C) Increased Aldosterone secretion.

D) Increased thirst stimulation.

E) Increased ADH secretion.

24. Which of the following are considered to be the main digestive processes?

A) Digestion – using enzymes to chemically break down nutrients into molecules small enough to be

absorbed.

B) Absorption – transportation of nutrient molecules into the blood.

C) Motility – movement along the entire tract (peristalsis) and mixing in the small intestine

(segmentation).

D) A and B

E) All of the above

27. Which of the following is FALSE?

A) The ileocecal sphincter regulates flow from small intestine to colon.

B) The cecum is small and not functional in humans.

C) The cecum is small and not functional in horses.

D) Inflammation of the appendix is called appendicitis.

E) The main function of the colon is to absorb water, which transforms chyme into feces.

Answer 1

22,

Answer is increased thirst stimulation.

Angiotensin II had no direct effect on thirst stimulation. Angiotensin act on the kidney and release ADH hormone which lead to sodium and water retention. It will stimulate the thirst.

Angiotensin II directly act on the kidney and enhance sodium reabsorption.

The major function of Angiotensin II is act on the blood vessels and lead to vasoconstruction.

24,

All of the above are the major digestive processes.

Absorption is take place in the intestines and stomach, digestion also a digestive process take place in the stomach. Mortility of intestine is needed to proper digestion.

27,

Answer is cecum is small and not functional in humans is false.

Cecum is functional in human it help in absorbing water and minerals.

ileocecal sphincter is situated between small intestine and colon which regulate the flow of food particles from small intestine to large intestine.

Colon is help in absorbing water from chyme and convert it into feces.
