Question

Most of the absorption of nutrients into the bloodstream 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 consists of three parts: the duodenum, jejunum, and ileum, and is specifically adapted for nutrient absorption due to its large surface area created by villi and microvilli.

The **large intestine**, on the other hand, primarily absorbs water and electrolytes, along with some vitamins produced by gut bacteria (such as vitamin K and some B vitamins). Its main functions are to form and eliminate waste (feces) rather than to absorb nutrients.
