The digested food is taken up by the walls of the small intestine. The inner lining of the small intestine has numerous finger-like projections called villi which increase the surface area for absorption.
The villi are richly supplied with blood vessels which take the absorbed food to each and every cell of the body, where it is utilized for obtaining energy, building up new tissues and the repair of old tissues.

∙ 11y agoThe inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue. Structurally, the mucosa is covered in wrinkles or folds called plicae circulares, which are considered permanent features in the wall of the organ. They are distinct from rugae which are considered non-permanent or temporary allowing for distention and contraction. From the plicae circulares project microscopic finger-like pieces of tissue called villi (Latin for "shaggy hair"). The individual epithelial cells also have finger-like projections known as microvilli. The function of the plicae circulares, the villi and the microvilli is to increase the amount of surface area available for the absorption of nutrients.Type your answer here...

Which parts of food are digested in the small intestine?
Digestion and absorption of many carbs, especially simple carbs start in your mouth and typically end in your stomach. Some more complex carbs are digested in small intestines. Almost all fats and proteins are digested and absorbed in the small intestine. In fact, the majority of absorption and digestion happens here. Typically very minimal is absorbed and digested in the large intestine. The one thing the large intestine does really well is to absorb water. This is why your stool is exceptionally watery when you have diarrhea as it has passed through the large intestine much too quickly to absorb the appropriate amount of water.
