C. The extrisnis neurons that innervate the enteric nervous system.

Answer 1

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

• The hepatoportal vein carries blood to liver from intestine.
• The toxin if any present is prevented to enter in the body.

2. C . It contains 3 layers of smooth muscle that contract to mechanically break up food particles and propel food foward by peristalsis

• The three layers of muscles of stomach is longitudinal, circular and oblique.
• Peristalsis is associated with food diesgtion.

3.D. Slow gastic emptying to ensure that nutrients entering the small intestine are digested and absorbed.

• Food travels intestine slowly.
• Nearly all nutrients are absorbed from intestine.

4.A. Pacesetter cells of the enteric nervous system

1. These cells are innervated with autonomic nervous system.

They play important role in GI moti liye
