👉 The term "ileum" is a Latin word that refers to the large intestine, which is located at the lower end of the small intestine. It plays a crucial role in absorbing nutrients from food and storing them for later use. The ileum is also involved in the digestive process by secreting digestive enzymes like lactase and amylase. Additionally, it helps regulate the balance of gases in the stomach and intestines through its muscular structure.
