NEET PG DENTAL EXAM

Detailed explanation-1: -Villi are present in the small intestine to increase the surface area of absorption. The stomach, on the other hand, is an organ that primarily stores food temporarily, along with helping in digesting proteins. Hence, the presence of villi is more justified in the small intestine and not in the stomach.

Detailed explanation-2: -Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through.

Detailed explanation-3: -The large intestine consists of the colon, rectum, and anal canal. The wall of the large intestine has the same types of tissue that are found in other parts of the digestive tract but there are some distinguishing characteristics. The mucosa has a large number of goblet cells but does not have any villi.

Detailed explanation-4: -Villi are finger-like projections which are richly supplied with blood vessels. They are present in the inner lining of the small intestine and help in the absorption of nutrients by increasing the surface area for absorption.
