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.

What is the rhythmic wavelike motion produced by smooth muscles in tubular visceral organs?
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 causes the wavelike movements in earthworms?
Muscular contractions.
The rhythmic contractions of the esophagus are called what?
Peristalsis is the term for the rhythmic contractions of the esophagus. These wavelike contractions move food toward the stomach.
The partially digested food is then moved by wavelike contractions known as?
Peristalsis.
What is the name of the wavelike constructions that propel food along the gut?
The wavelike contractions that propel food along the gut are called peristalsis. This process involves rhythmic, coordinated muscle contractions in the digestive tract, pushing food through the esophagus, stomach, and intestines. Peristalsis is crucial for the proper movement and digestion of food.
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 the term for Wavelike contraction of smooth muscles that move material through the digestive system?
peristalsis
How does food pass your organs?
By rhythmic movements called peristalsis. They are wavelike contractions of smooth muscle that propel food through the GI 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 is dynamic contractions?
Dynamic contractions refer to muscle contractions that occur during movement, where muscles lengthen or shorten as they generate force. This type of contraction can be further classified into concentric contractions, where muscles shorten while producing force, and eccentric contractions, where muscles lengthen under tension. Dynamic contractions are essential for various physical activities, including walking, running, and lifting, as they enable the body to adapt to changing conditions.
What is clonus?
Involuntary contractions of the muscles, classically the long muscles associated with standing (the anti-gravity muscles).
