Question

Quizplus · Accepted Answer

Iron is primarily absorbed in the duodenum, which is the first part of the small intestine. The acid in the stomach helps to convert dietary iron into a more absorbable form, and then the iron is transported into the duodenum for further absorption. The proximal jejunum also contributes to iron absorption, but to a lesser extent than the duodenum. The ascending colon is part of the large intestine and is not involved in iron absorption.
