What causes wavelike contractions of muscles called peristalsis to begin when food moves through the digestive tract?
Peristalsis is initiated by the stretching of the digestive tract walls when food enters, which stimulates mechanoreceptors. This triggers the release of neurotransmitters that activate smooth muscle contractions in a coordinated manner. These contractions move in a wave-like pattern, propelling food along the digestive tract. Additionally, the autonomic nervous system plays a key role in regulating the intensity and frequency of these contractions.

What is produced by wavelike contractions of muscles.?
Wavelike contractions of muscles, known as peristalsis, primarily produce movement in the digestive tract, facilitating the propulsion of food along the esophagus, stomach, and intestines. This rhythmic contraction and relaxation of smooth muscle help in the breakdown and absorption of nutrients. Additionally, peristalsis plays a role in the elimination of waste from the body.
Peristalsis is example of what type of muscle?
Peristalsis is the contraction of the digestive muscles. Peristalsis is the contractions that occur in the smooth muscles of the body.
What is the term for Wavelike contraction of smooth muscles that move material through the digestive system?
peristalsis
What term describes a series a wavelike contractions of the smooth muscles in a single direction?
The wavelike contractions of the smooth muscle in the gastrointestinal system are called peristalsis. The purpose of peristalsis is to push boluses of food along the gastrointestinal tract. This is achieved by the waves of contractions in the smooth muscle followed by relaxation of the muscles, pushing the bolus (ball of food) a bit further along the digestive tract with each contraction. These contractions move food or chyme through the esophagus, and intestines. The same contractions also move urine down the ureter to the bladder.
What is the rhythmic wavelike motion produced by smooth muscles in tubular visceral organs?
Peristalsis
Which process propels the food through the digestive tract?
Peristalsis is the process that propels food through the digestive tract. It involves rhythmic contractions of the muscles in the gastrointestinal tract that push food and nutrients along the digestive system.
Involentary waves of muscles contractions that keep food from moving in one direction through the digestive system are called?
peristalsis
Is peristalsis is chemical change?
No. Peristalsis is a physical process in which the involuntary muscles of the digestive tract contract and move food along.
What is the muscle action that mixes chyme with digestive juices while another muscular action that moves food through the digestive system?
The muscle action that mixes chyme with digestive juices throughout the digestive system is called Peristalsis. Peristalsis are wave-like of contractions and expansions of muscles. The muscles help to move the bolus (food) through the digestive tract. Peristalsis are located all over the digestive tract.
What is a wavelike motion that pushes food downward?
Peristalsis is the wavelike motion of muscles that pushes food downward through the digestive tract. It helps propel food and liquids from the esophagus to the stomach and through the intestines for digestion and absorption.
What are muscular contractions that push food through the digestive system?
Peristalsis are muscular contractions that push food, partially digested food, and solid waste through the digestive system. Peristalsis is under the involuntary nervous system. No matter how hard you might try, you cannot willfully control or influence peristalsis.
What is perstalsis?
Food is pushed down the oesophagus by a series of contractions. The part of the oesophagus just above the ball of food contracts and pushes it down. then it relaxes and the next part of the oesophagus contracts. this wavelike movement, controlled by muscles, is called peristalsis. It occurs all the way down the alimentary canal.
