Most of the gastrointestinal tract - including the large intestine - is made of the same tissue types. Imagine the intestine as a hollow tube made up of three distinct layers; starting from the inside out, they are called:
- The mucosa: the innermost surface of the mucosa consists of a single layer of epithelial cells with a basal membrane of connective tissue supplied by blood and lymph vessels, and finally a narrow band of smooth muscle.
- The submucosa: a loose matrix of connective tissue containing blood and lymph vessels, and the ganglia of enteric neurons.
- The muscularis externa: two layers of smooth muscle running at right angles to one another; the inner layer encircles the wall of the intestine, and the outer layer runs lengthways.

Does colon cancer occur most often in the large or small intestines?
Colon cancer is a type of cancer that occurs in the large intestine (colon), which is the final part of the digestive tract12. The large intestine is about 5 feet long and absorbs water and salt from the food that passes through it. The small intestine, also called the small bowel, is a long tube that connects the stomach and the large intestine. It is about 20 feet long and is responsible for digesting and absorbing nutrients from the food that enters it. Cancer of the small intestine is much less common than cancer of the large intestine. There are different types of small bowel cancer, such as adenocarcinoma, neuroendocrine tumors, lymphoma, and sarcoma. Therefore, colon cancer occurs most often in the large intestine, not the small intestine.

The way it goes is this: one type of cell makes tissues, many tissues make an organ. Many organs make an organ system and many organ systems make an organism.
Length of large intestine in fetal pig?
Fetal pigs are most often used in dissection classes because aspects of their biology closely resembles ours. The large intestine of a fetal pig is typically 1-3 feet in length.
What type of movements take place in the large intestine and why?
The type of movement that occurs in the large intestine is called peristaltic action. This is a series of rhythmic contractions of smooth muscles that are in the walls of the intestines. The intestines are composed of many small pouches called haustra. And as peristaltic action continues, feces in the large intestine move from one haustra to another until it finally reaches the anal canal and anus. Then when the internal and external sphincters relax, the feces is expelled from the body.
