Question

most of the absorption of nutrients into the bloodstreem takes place in the large intestine

Answer 1

Actually, most of the absorption of nutrients into the bloodstream occurs in the **small intestine**, not the large intestine. The small intestine, which is divided into three parts—the duodenum, jejunum, and ileum—is primarily responsible for the digestion and absorption of carbohydrates, proteins, and fats, as well as vitamins and minerals.

The large intestine (or colon) is mainly involved in the absorption of water and electrolytes and the formation and storage of feces. While it does absorb some small amounts of nutrients and certain vitamins (like vitamin K and some B vitamins produced by gut bacteria), the vast majority of nutrient absorption happens in the small intestine.
