Answers
Answer:
Peristalsis refers to the involuntary contraction and relaxation of the muscles of the digestive tract to move the food through the digestive system. The creation of wave-like muscle contractions pushes the food easily to the different processing stations in the digestive tract.
A ring-shaped muscle that relaxes or tightens to open or close a passage or opening in the body. Examples are the anal sphincter (around the opening of the anus) and the pyloric sphincter (at the lower opening of the stomach).
Answer:
Throughout the digestive tract, smooth muscle peristalsis aids in transporting food. From the esophagus, the bolus passes through a sphincter (muscular ring) into the stomach. All sphincters located in the digestive tract help move the digested material in one direction.
