Intestine Transplant. What Is the Small Intestine? The small intestine is made up of three segments, which form a passage from your stomach the opening between your stomach and small intestine is called the pylorus 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.
The duodenum also uses bile from your gallbladder, liver, and pancreas to help digest food. 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. How can the small intestine digest so much? The small intestine has three features which allow it to have such a huge absorptive surface area packed into a relatively small space: Mucosal folds: The inner surface of the small intestine is not flat, but thrown into circular folds.
The large intestine , which doctors also call the colon, has a larger diameter than the small intestine. The primary function of the large intestine is to reabsorb fluids, electrolytes, and vitamins and then form and propel feces toward the rectum for elimination. It contains four distinct parts:.
As with the small intestine, the total length of the large intestine varies from person to person. Heavier people, younger people, and males generally have longer intestines. In most people, it is about 5 ft long. The colon is the longest part of the large intestine, while the cecum measures about 2.
The rectum is about 7. Some people with certain health conditions may need to undergo a colon resection , or colectomy, to remove part of or the whole large intestine. People who find it difficult to visualize the length of the intestines may find these comparisons helpful:.
The length of the intestines can vary greatly among individuals. Research suggests that the combined length of the small and large intestines is at least 15 ft in length. The small intestine can measure about 9—16 ft, while the large intestine is roughly 5 ft long.
The intestines have the important role of helping break down and absorb nutrients from food and drink. Learn more about the parts, dimensions, and functions of the intestines.
