Question

Part B How is the mucosa layer of the large intestine similar to that of the small intestine? Choose all that apply. Both have goblet cells for lubrication and protection. Both have villi to increase surface area for absorption. Both have a muscularis mucosa layer that constricts for peristalsis. Both have absorptive cells that absorb fats. Both contain Mucosa Associated Lymphoid Tissue (MALT) in the lamina propria to prevent bacteria from entering the blood stream. Both have absorptive cells that absorb water.

Explanation / Answer

Both small and large intestine have goblet cells which help in lubrication and protection. These cells produce mucus and thereby have a protective function.

Villi are only present in small intestine and not in largr intestine.

Both have muscularis mucosae which constrict with peristalsis and propulse the food downwards.

Absorption of fat occurs mostly in small intestine and they have enterocytes through which by the process of simple diffusion the fatty acids and 2- monoglycerides get absorbed.

MALT ( mucosal associated lymphoid tissue) is present in lamina propria of the small intestine as Peyer's patch where it prevents the micro organisms from entering and affecting the body. MALT is not present in large intestine

Enterocytes are the cell which are involved in water absorption but majority of the water absorption occurs in large intestine and sugar,fat,aminl acids are costly absorbed in the small intestine but some water is absorbed in small intestine also. So, both have enterocytes which absorb water
