Question

Mention the role of following in digestion a) saliva b) bile juice c)villi​

Answer 1

Explanation:

Saliva-

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

Bile-

Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.

Juice -

How do digestive juices in each organ of the GI tract break down food?

Digestive juices contain enzymes—substances that speed up chemical reactions in the body—that break food down into different nutrients.

villi -

Villus, plural villi, in anatomy any of the small, slender, vascular projections that increase the surface area of a membrane. ... The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions.
