Full origin of peristalsis →Frequently Asked Questions
Where does peristalsis happen in the body?
Mainly in the oesophagus, stomach and intestines, but the same wave motion also moves urine down the ureters and eggs along the fallopian tubes.
What is the difference between peristalsis and segmentation?
Peristalsis is a directional wave that transports contents forward. Segmentation is a back-and-forth churning in the small intestine that mixes food with digestive juices without moving it along much.
Can you control peristalsis?
No. It is driven by smooth muscle under involuntary nervous control, which is why swallowing continues automatically once you have started it.
