Answer 1

The small intestine has a double layer of smooth muscle: an inner circular layer and an outer longitudinal layer. The colon has three narrow parallel bands called teniae coli that give it a pouch-like appearance.

Step-by-step explanation:

The small intestine is made up of a double layer of smooth muscle known as the muscularis. This layer consists of an inner circular layer and an outer longitudinal layer, which work together to promote digestion and move food along the canal.

In contrast, the large intestine, specifically the colon, also has two layers of muscle but with a different arrangement. The longitudinal layer of the colon is segregated into three narrow parallel bands called teniae coli, which give the colon a series of pouches or haustra.

Overall, the muscularis of the alimentary canal contains different muscle layers tailored to the specific functions of each organ.
