Question

Which of the following is TRUE?

The hepatic portal vein transports water-soluble vitamins, amino acids and monosaccharides from the small intestine to the liver.

The hepatic portal vein transports lipids from the small intestines to the liver

The lymphatic system transports water-soluble vitamins, amino acids and monosaccharides from the small intestine to the liver

Question 2

Which of the following is TRUE about the stomach?

It contains 3 layers of smooth muscle that contract to mechanically break up food particles and propel food forward by peristalsis

It contains Endocrine glands that secrete Gastrin into the stomach

Small polypeptides are absorbed by endocytosis from the stomach

Question 3

The intestinal phase of digestion _________________________.

Slows gastric emptying to ensure that nutrients entering the small intestine are digested and absorbed.

Stimulates the gastroenteric reflex

Maintains homeostasis of blood pH

Prevents gastroesophageal refulx

Question 4

The interstitial cells of Cajal are _________________________.

Pacesetter cells of the enteric nervous system

Afferent sensory neurons of the enteric nervous system

The extrinsic neurons that innervate the enteric nervous system

Question 5

Which monosaccharide uses secondary active co-transport with sodium (a SGLT) for absorption across the apical membrane of the Small Intestine?

Glucose

Lactose

Sucrose

Maltose

Answer 1

Question 3

The intestinal phase of digestion

Stimulates the gastroenteric reflex

Question 4

The interstitial cells of Cajal are

Pacesetter cells of the enteric nervous system generates impulses responsible for peristaltic movements

Question 5

Which monosaccharide uses secondary active co-transport with sodium (a SGLT) for absorption across the apical membrane of the Small Intestine?

Glucose

Membrane transport proteins use the energy created by sodium and potassium ion transport by the ATPase pump to transport glucose across the apical membrane in small intestine.
