Question

Name the physiological processes occurring in part 1 and 2​

Answer 1

Columnar Epithelium: Where absorption and secretion occur, as in the inner lining of the intestine, tall epithelial cells are present and are named as cohunnar epithelium.

In the respiratory tract, on the outer surfaces of epithelial cells there are hair like projevtions called cilia. These cilia can move, and their movement pushes the mucus forward to clear it. This type of epithelium is named as ciliated columnar epithelium.
