Dear student,
Please find below the solution to the asked query
b. The function of anal sphincter is to control the exit of feces from the digestive system through the anus. There are two types of anal sphincters, internal and external. Internal anal sphincter is involuntary and not under our control. While external anal sphincter is voluntary.
c. Villi are the tiny finger-like projections present in the inner lining of the small intestine. These projections increase the surface area of the small intestine for efficient food absorption. Please post other parts in a separate thread.
