What is an ileum in a guinea pig and where is it?

The ileum is the final section of the small intestine in a guinea pig, playing a crucial role in nutrient absorption. It follows the jejunum and connects to the cecum, which leads to the large intestine. The ileum is typically located in the lower abdomen and is characterized by its thinner walls and numerous villi that increase surface area for absorption. Proper functioning of the ileum is essential for the guinea pig's overall digestive health.
