Verified step by step guidance

Understand the role of the large intestine in the digestive system. The large intestine is primarily involved in the absorption of water and electrolytes, rather than digestion of proteins or production of digestive enzymes.

Recognize that the digestion of proteins primarily occurs in the stomach and small intestine, where enzymes like pepsin and trypsin break down proteins into amino acids.

Identify that the production of digestive enzymes is mainly a function of the pancreas and the small intestine, not the large intestine.

Note that the absorption of nutrients, such as carbohydrates, proteins, and fats, occurs predominantly in the small intestine, where villi and microvilli increase the surface area for absorption.

Conclude that the large intestine's main function is to absorb water and electrolytes from the remaining indigestible food matter, forming solid waste (feces) to be excreted from the body.
