The intestine is long to maximize the surface area available for absorption, which is the primary function of the large and small intestines.
The small intestine is the longest section of the intestines. It's called "small" because it has a narrower diameter than the large intestine.
The alimentary canal consists of the mouth, esophagus, stomach, small intestine, and large intestine. It is the main part of the digestive system. During the digestion process, the gallbladder secretes bile into the duodenum, which is the first section of the small intestine.
The ileum is the longest part in the small intestine. It has a length of around 2-4m. It is the last section in the small intestine.
the large intestine is 1.5 meters long, while the small intestine can be from 4-7 meters long. Though it is called the small intestine, it is actually the longest part of the digestive tract.
I don't know what it is but I know its not stomach... most likely the large intestine.
The section of the small intestine where nutrients are absorbed are the jejunum and the ileum. Once the digestive process takes place in the small intestine, food particles go to the large intestine.
The large intestine is the shorter but wider section of the intestine. The small intestine is longer but narrower.
The last section of the small intestine is the ileum.
The duodenum is the section of the small intestine that is attached to the stomach.
The second, or middle section of the large intestine is the transverse colon.
The ascending colon is the first section of the large intestine.
The ilium is about 3 meters long, and contains villi similar to the jejunum. It absorbs mainly vitamin B12 and bile acids, as well as any other remaining nutrients. It joins to the cecum of the large intestine at the ileocecal junction.
