Function: Chemical digestion of food and absorption of nutrients into your blood. Longest section of your digestive tract. Your small intestine is around five metres long, making it the longest section of your digestive tract. Although it is longer than your large intestine it has a smaller diameter. This is why it's called the small intestine.
The small intestine, also known as the small bowel, is where digestive juice from your liver and pancreas mixes with food to break it down into useable nutrients. It is also responsible for absorbing these nutrients from the food you eat. Over 20 feet in length, the small intestine also delivers leftover product, waste, to your colon, upward of 1 liter per day.
