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.
The enlarged section of the alimentary canal is commonly referred to as the stomach. It serves as a key digestive organ where food is mixed with gastric juices, breaking down nutrients for absorption. The stomach's muscular walls facilitate the mechanical and chemical digestion of food before it moves into the small intestine for further processing.
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 distal coiled portion of the small intestine is called the ileum. It is located between the jejunum and the cecum (the beginning of the large intestine) and is the longest section of the small intestine. The ileum is primarily involved in the absorption of nutrients, especially vitamin B12 and bile salts.
The last section of the small intestine is the ileum.
The second, or middle section of the large intestine is the transverse colon.
The duodenum is the section of the small intestine that is attached to the stomach.
