Question

1.Which of these nutrients canNOT be absorbed in the large intesting?

-large proteins,electrolytes,water, or some short chain fatty acids.

2.the formation of chyme occurs when the bolus mixes with the secretions from the?

-pancreas, large intestine, gallbladder, or stomach.

3.which of the following is not an organ that stimulates or inhibits gastric secretions?

-r****m, brain, stomach or small intestine.

4.which of the following is needed for the digestion of fat?

-amylase,bile,HCI, or pepsin.

5.which of the following stimulates the liver to secrete bile?

-CCK, secretin,gastrin or pepsinogen?

6.which of the following stimulates the contraction of the gallbladder to release bile?

-CCK, gastrin,secretin or somastostatin?

7. which of the following organs is a baloon-like structure responsible for storage & release of bile?

-liver,stomach,gallbladder or pancreas

Answer 1

1.  Large proteins - which is the reason the body produces so many proteases.

2.  Stomach.  Specifically, the stomach produces HCl and pepsinogen, which is converted to the active protease pepsin, which mixes with the food, and the mixture is combined by contractions of the stomach into acid chyme.

3.  The r****m does not stimulate or inhibit gastric secretions.

4.  Bile is not required for the digestion of fat - lipase digests it.  However, bile emulsifies fat, and makes it much easier for the lipase to break down the fat.  

5 and 6.  CCK is produced by the intestine, and released in the duodenum, and causes the release of bile from the gall bladder and digestive enzymes from the pancreas.  While bile salts are produced in the liver, they are stored in the gall bladder.  So far as I can discover, it is R (+)-alpha-lipoic acid (RLA) that stimulates the liver to produce bile salts, not one of the regular digestive enzymes.

7.  Again, the bile is stored in the gall bladder.

Answer 2

1.Which of these nutrients canNOT be absorbed in the large intestine?

-large proteins,electrolytes,water, or some short chain fatty acids.

WATER IS ABSORBED IN THE LARGE INTESTINE THE REST ARE ABSOBED IN THE SMALL INTESTINE

2.the formation of chyme occurs when the bolus mixes with the secretions from the?

-pancreas, large intestine, gallbladder, or stomach.

STOMACH

3.which of the following is not an organ that stimulates or inhibits gastric secretions?

-r****m, brain, stomach or small intestine.

4.which of the following is needed for the digestion of fat?

-amylase,bile,HCI, or pepsin.

BILE

5.which of the following stimulates the liver to secrete bile?

-CCK, secretin,gastrin or pepsinogen?

CCK

6.which of the following stimulates the contraction of the gallbladder to release bile?

-CCK, gastrin,secretin or somastostatin?

CCK

7. which of the following organs is a baloon-like structure responsible for storage & release of bile?

-liver,stomach,gallbladder or pancreas

GALLBLADDER
