Individuals that have a genetic condition where they lack bile salt production would:
All of the choices are correct
Two of the choices are correct
Not be able to add a polar head to the lipid for lipase digestion
Not be able to produce micelles and absorb fat
Not be able to complete carbohydrate digestion
3.
If an individual had damaged their medulla oblongata, what would be altered with their digestive system?
The production of HCl for the stomach would prevent enzyme activation
The swallowing reflex would be damaged and food would not travel down the esophagus
The enteric nervous system would prevent movement of digested materials along the tract
There would be no damage
The production of bile salts would prevent micelle production
4.

Descending limb of the loop of Henle
Ascending limb of the loop of Henle
Proximal tubule
5.
What statement is false about atrial natriuretic peptide (ANP)?
It inhibits Na+ reabsorption in the distal part of the nephron
None of the statements are correct
It is released from the cardiac atria when the ECF volume is decreased
It inhibits aldosterone secretion by the adrenal cortex
It inhibits sympathetic nervous activity to the heart and blood vessels
6.
Which absorptive process occurs?
None of the choices are correct
All of the choices are correct
Monoglycerides (fat) is absorbed by active transport and enters the lacteal (lymph)
Water-soluble vitamins are carried out by micelles
Glucose (carbohydrate) is absorbed by active transport and enters the blood
7.
With a peptic (gastric) ulcer:
These are usually caused by bacterial infections and can compromise the mucosal barrier and stomach wall
These can be caused by excessive neural stimulation
These are usually caused by bacterial infections
These can be caused by excessive neural stimulation , re usually caused by bacterial infections and can compromise the mucosal barrier and stomach wall
These can compromise the mucosal barrier and stomach wall
Explanation / Answer
Ans-4- Proximal tubule . because 70% of tubular reabsorption occurs in PCT alongwith solutes including sodium,water is also re absorbed because water follows sodium and is reabsorbed quickly and mostly in pct.
