Question

What is the function of rectum?

Answer 1

Rectum is the final portion of the large intestine that end at the anus opening. It is the last point before the feces is eliminated through the anal cavity.

Rectum acts as temporary storage site for feces. Walls of rectum absorbs electrolytes (sodium, pottasium and chloride) and water from the left-overs of digested food. In the rectum the undigested food is decomposed by anaerobic bacteria and the stool is thickened through water absorption and mixed with mucus.
