Organs: Small and Large Intestines

The intestine is a muscular tube which extends from the lower end of your stomach to your anus, the lower opening of the digestive tract.

•The small intestine is made up of three segments, which form a passage from your stomach to your large intestine:

Duodenum: This short section is the part of the small intestine that takes in semi-digested food from your stomach through the pylorus, and continues the digestion process. 

Jejunum: The middle section of the small intestine carries food through rapidly, with wave-like muscle contractions, towards the ileum.

Ileum: This last section is the longest part of your small intestine. The ileum is where most of the nutrients from your food are absorbed before emptying into the large intestine.

Large intestine 

Your large intestine is about five feet (or 1.5 meters) long. The large intestine is much broader than the small intestine and takes a much straighter path through your belly, or abdomen. Its job is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.The large intestine is made up of the following parts:

Cecum, Rectum & Colon 

The colon consists of four parts:Sigmoid colon,Ascending colon,Transverse colon, and Descending colon.
