Final Answer:
The colon walls are made up of axial strips of muscle called the taeniae coli, and outpouches of the wall are called haustra.
Step-by-step explanation:
The colon, or large intestine, is divided into distinct longitudinal bands of muscle called taeniae coli. These axial strips run along the length of the colon and contribute to its segmented appearance. The haustra are pouch-like structures that result from the contraction of the taeniae coli. As the taeniae coli contract, they cause the colon to bunch up, forming the haustra.
This structural arrangement helps with the movement of material through the colon, facilitating the absorption of water and electrolytes. The taeniae coli and haustra are characteristic features of the colon, contributing to its unique anatomy and function in the digestive system.
