Question

The contraction and expansion movement of the walls of the food pipe is called:
(a) translocation
(b) transpiration
(c) peristaltic movement
(d) digestion

Answer 1

the contraction and expansion of the walls of the food pipe is known as peristalsis.

Option c

Explanation:

• Peristalsis is one of the movement which helps in the movement of food down the oesophagus. There is a series of contraction in the wall both proximal and distal end to the food bolus.

• However there is expansion between the two contracted and. There is a wave like motion which helps to move the food down the oesophagus. It is one of the most important muscle contraction that helps in digestion.

Answer 2

Answer:

(c) Peristaltic movement

Explanation:

Peristaltic movements also known as peristalsis is a series of wave-like contractions and relaxations of muscles to move the food forward in the digestive tract. Peristalsis starts from the esophagus, after the churning of food in the mouth and makes its bolus. Bolus is forwarded by the esophagus/food pipe in the stomach by the peristalsis. The partially digested food in the stomach is further churned and transferred to the small intestine, where it is called chyme. Peristalsis remains to continue in the small intestine and wave-like motions aid the bloodstream to absorb nutrients from the food and then transfer it to the large intestine, where it is called chyle. Peristaltic movements in the large intestine help in the absorption of water from the food and transfer the waste material further for excretion.
