b. from the beginning of the esophagus to the anus.

Step by step solution

01

Peristalsis is a series of wave-like muscle contractions that moves food or fluids through the digestive tract. It helps in the process of digestion by propelling the contents of the digestive system forward. #Step 2: Understand the human digestive system#

The human digestive system consists of several organs, including the mouth, esophagus, stomach, small intestine, and large intestine (colon). The digestive process begins in the mouth and continues along the digestive tract until the anus. For this exercise, we need to focus on the organs involved in peristalsis. #Step 3: Identify where peristalsis occurs in the digestive system#
02

Peristalsis occurs throughout the digestive system except for the mouth. It begins in the esophagus, where the food is pushed down toward the stomach. In the stomach, muscular contractions mix the food with gastric juices and push it through to the small intestine. Peristalsis continues in the small and large intestine, pushing the partially digested food forward and allowing nutrients to be absorbed from the small intestine, and water from the large intestine. Finally, peristalsis helps to eliminate waste from the body via the rectum and anus. #Step 4: Select the correct option#

Based on our understanding of peristalsis and the human digestive system, the correct answer should be the option that states peristalsis occurs from the esophagus to the anus. So, the correct answer is: b. from the beginning of the esophagus to the anus.
