Where does most nutrient absorption occur?

Question

Quizplus · Accepted Answer

Most nutrient absorption occurs in the small intestine, primarily in the jejunum. The jejunum has a large surface area due to its long length and numerous folds, as well as the presence of villi and microvilli, which increase the absorption capacity. The stomach mainly functions in the breakdown of food through the action of acid and enzymes, while the large intestine primarily absorbs water and electrolytes, but not nutrients. The mouth also helps with the initial breakdown of food through chewing and the mixing of food with saliva, but not much absorption occurs there.
