HUMAN NUTRITION

Detailed explanation-1: -The goblet cells consume excess water from the undigested food residues in the large intestine.

Detailed explanation-2: -By the time food reaches the large intestine, the work of absorbing nutrients is nearly finished. The large intestine’s main job is to remove water from the undigested matter and form solid waste (poop) to be excreted.

Detailed explanation-3: -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-4: -The large intestine reabsorbs water from the undigested food and stores waste until elimination. Carbohydrates, proteins, and fats are the primary components of food. Some essential nutrients are required for cellular function but cannot be produced by the animal body.
