NEET BIOLOGY

Detailed explanation-1: -Absorptive columnar epithelium is characterized as having a striated boarder on its apical side, this border is made up of non-motile microvilli allowing for increase surface area for absorption. these are known as ciliated columnar epithelium.

Detailed explanation-2: -Simple columnar epithelium This type of epithelia lines the small intestine where it absorbs nutrients from the lumen of the intestine.

Detailed explanation-3: -Simple columnar epithelium is especially adapted to absorption of substances because of the cell surface characteristic called microvilli. These microvilli are tiny finger-like structures, which increase the surface area of the cell, thus allowing for more efficient absorption.

Detailed explanation-4: -They are also important for the uptake of water, ions, and vitamins. Some cells of this epithelium are involved in secreting the hormones of the digestive system that regulate digestion, peristaltic movement and water balance. Other cells secrete mucus or play a role in immunity.

Detailed explanation-5: -Types of epithelial cells in your body Simple columnar epithelium: This type of epithelium is often specialized for absorption and usually has apical cilia or microvilli. These cells line your stomach and intestines.
