NEET PG DENTAL EXAM

Detailed explanation-1: -The role of the ascending colon is to absorb the remaining water and other key nutrients from the indigestible material, solidifying it to form stool. The descending colon stores feces that will eventually be emptied into the rectum.

Detailed explanation-2: -Absorption of ingested water and most solutes occurs in the proximal small intestine, therefore the rate at which beverages are emptied from the stomach is an important factor in determining the rate of water absorption.

Detailed explanation-3: -The large intestine (colon) is responsible for reabsorption of water, sodium, potassium, and vitamin K. However, retrospective studies have shown that the large intestine also is responsible for absorption of small amounts of calcium and magnesium.
