Quizplus · Accepted Answer

Most absorption of nutrients, water, and electrolytes occurs in the small intestine, particularly in the jejunum and ileum. The large surface area of the small intestine, aided by the presence of villi and microvilli, facilitates this process. The esophagus and stomach primarily serve as transit areas for food and do not play a significant role in absorption. The colon is mainly responsible for water and electrolyte absorption but does not absorb nutrients to a significant extent.
