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.

Expert Solution

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.

Angiotensin II. Describe in detail the physiology of Angiotensin II. Include a detailed description of (1) what it is, (2) where it comes from, and (3) how it is activated. Describe in detail 3 mechanisms that act to activate it (the RAS system) and how and when they operate. Lastly describe each of the physiological effects of AngII and explain how each of these effects contribute to homeostasis. Discuss each separately. Be sure to make clear how each effect contributes...

Which of the following would be the result of increasing the temperature at which GC is run? I knew this would cause a faster elution time because temperature increases kinetic energy but I am not sure how this results in poorer seperation. Can you explain what it means by "seperation" . I watched videos on the Gas Chromatography but I am not clear on how things are seperated----i thought that the more volatile will adhere less to the liquid stationary...

a. Would increasing the oxidation number, say Fe(II) to Fe(III), result in any change in crystal field splitting for an octahedral complex? Explain your choice. b. In a tetrahedral geometry all oxidation states are high spin (HS). What does this reveal about crystal field splitting Δtetrahedral versus Δoctahedral? Explain (n.b. There is only one known Co complex that does not follow this generalization and no one has been able to explain why this one complex does not follow the rule.)
