Question

Which of the following is a similarity between peristalsis and haustral churning?

A. They both move chyme through the colon
B. They both compact undigested material into stool
C. They both eliminate feces from the rectum
D. They both break down carbohydrates and other substances in chyme

Answer 1

Both peristalsis and haustral churning are types of movements involved in mechanical digestion in the large intestine. They both help to move chyme through the colon, but peristalsis is responsible for the larger-scale movement, while haustral churning facilitates mixing and absorption of water.

Step-by-step explanation:

Both peristalsis and haustral churning are types of movements involved in mechanical digestion in the large intestine. Peristalsis is a wave-like muscle contraction that moves food through the digestive tract in one direction. Haustral churning, on the other hand, involves slow-moving contractions that mix and propel the food residue in the transverse and descending colons. Both peristalsis and haustral churning help to move chyme through the colon, but peristalsis is responsible for the larger-scale movement, while haustral churning facilitates mixing and absorption of water in the large intestine.

The similarity between peristalsis and haustral churning is that they both involve muscle contractions that move chyme through the digestive tract. Peristalsis and haustral churning are both mechanical digestion methods, but peristalsis is characterized by waves of muscle contractions that propel food along the alimentary canal, while haustral churning involves segmented contractions that help mix the chyme and absorb water in the colon.
