The first photo is the large intestine. Large intestine actually have 3 parts; the colon, rectum and anus. It absorbs water and electrolytes. It is where foods turn into stool and being excreted from the body when you poop.

The middle photo is the ileum. It is the last part of the small intestine and connects to the first part (cecum) of the large intestine. The ileum helps to further breakdown foods coming from the stomach and small intestines. It absorbs nutrients such as minerals , vitamins, fats, carbohydrates, proteins and water from the foods so they can be used as fuels for the body.

The last photo is the smooth muscle. Smooth muscle tissues are found on the intestinal wall. It generates tonic contractions that maintains the proportions of the organ when the stomach is loaded with foods and forceful contractions.
