Question

what is peristalsis? Name some structures in which it occurs...marks-6

Answer 1

Here is your answer buddy,

Peristalsis is a series of wave like muscle contractions that move food to different processing stations in the digestive tract. The process of peristalsis begins in the oesophagous when a bolus of food is swallowed. The strong wave-like motions of the smooth muscle in the esophagus carry the food to the stomach, where it is churned into a liquid mixture called chyme.

Peristalsis then continues in the small intestine where it mixes and shifts the chyme back and forth allowing nutrients to be obsorbed into the blood stream through the small intestine walls.

Peristalsis concludes in the large intestine where water from the undigested food material is absorbed into the blood stream. Finally the remaining waste products are excreted from the body through the rectum and anus.

Hope this helps you.

Answer 2

Heya!! Here is your answer!

$<b>⭐When we eat food,the food is pushed down by a series of contractions.The part of the oesophagus just above the ball of food contracts and pushes it down.Then it relaxes and the next part of the oesophagus contracts to transport the food.$

⭐This wavelike movement, controlled by the muscles is known as PERISTALSIS.It occurs all the way down the alimentary canal.This is how the food passes down the alimentary canal (reffer to image).

EXPERIMENT:(For clearance)

Try squeezing a piece of eraser or a chalk through a tube(made of rubber) to see how peristalsis works.
