ANATOMY

Detailed explanation-1: -By the time indigestible materials have reached the colon, most nutrients and up to 90% of the water has been absorbed by the small intestine. 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.

Detailed explanation-2: -The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.

Detailed explanation-3: -The colon helps to absorb a small volume of water from the lumen (400ml/day).

Detailed explanation-4: -Your stools get hard and dry when your colon absorbs too much water. Constipation symptoms can include stomach cramps and feeling tired. Constipation can cause other health problems, such as hemorrhoids (red, swollen veins in the rectum).
