Question

1. summarize absorption and where it happens in our body.

Explanation:

Absorption is the process of nutrients from digested food entering the bloodstream. In the body, it mainly occurs in the small intestine. The small intestine has a large surface area due to villi and microvilli, which enhance absorption. Some absorption also happens in the stomach (e.g., certain drugs, alcohol) and the large intestine (e.g., water, some vitamins produced by gut bacteria).

Answer:

Absorption is the uptake of nutrients into the bloodstream. It mainly occurs in the small intestine (due to villi/microvilli for increased surface area), also in the stomach (e.g., alcohol, some drugs) and large intestine (e.g., water, some vitamins).
