Question

Digestive processes in the large intestine include:

A) Chemical digestion of carbohydrates
B) Absorption of water
C) Chemical digestion of fats
D) Absorption of most of the nutrients
E) Secretion of digestive enzymes

Answer 1

The large intestine's primary function in digestion is the absorption of water, certain vitamins, and leftover salts, not the absorption of most nutrients or the chemical digestion of carbohydrates and fats.

Step-by-step explanation:

The question is focusing on the functions of the large intestine. In terms of digestive processes, the large intestine is primarily responsible for the absorption of water and the formation of feces. It is not where most nutrients are absorbed; this occurs earlier in the small intestine. The key roles of the large intestine in digestion include:

• Absorption of water.
• Absorption of certain vitamins, electrolytes, and any leftover salts.
• The formation of feces from indigestible food residue.

Chemical digestion of carbohydrates and fats, the absorption of most nutrients, and the secretion of digestive enzymes occur mainly in the small intestine, not the large intestine. Therefore, the correct answer regarding the functions of the large intestine is: B) Absorption of water.
