Intestinal Jejunum Cutaway

The small intestine is responsible for most of the absorption of nutrients from food, with the absorption occurring mostly in the duodenum and jejunum. The tiny villi that line the small intestine create a huge surface area for absorption. Any remaining matter will pass along the colon to be excreted as feces. Size 34 x 17 x 10 cm approx.
