Question

define peristaltic movement,cilia?​

Answer 1

Answer:

A cilium, or cilia (plural), are small hair-like protuberances on the outside of eukaryotic cells. They are primarily responsible for locomotion, either of the cell itself or of fluids on the cell surface. They are also involved in mechanoreception.

The movement of food in the food pipe ( esophagus ) or in the small or large intestine in the presence of millions of finger like projections called as villi is known as peristaltic movement of food.
