Intestines

The intestines are a part of the digestive system, which is responsible for breaking down food and absorbing nutrients. There are two main sections of the intestines: the small intestine and the large intestine.

Small Intestine

The small intestine is where the majority of digestion and nutrient absorption takes place. It is approximately 20 feet long and is divided into three sections: the duodenum, the jejunum, and the ileum. The walls of the small intestine are lined with tiny finger-like projections called villi, which increase the surface area for absorption of nutrients into the bloodstream.

Large Intestine

The large intestine, also known as the colon, is wider in diameter but shorter in length compared to the small intestine. Its primary function is to absorb water and electrolytes from the remaining indigestible food matter and to form feces for elimination. The large intestine is also home to a large population of beneficial bacteria that aid in the final stages of digestion and produce certain vitamins.
