What else can I help you with?
Food moves along the digestive tract as the result of contractions of what?
smooth muscles.
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.
Which of the mucsle types are volentary and which are involentary?
Smooth and cardiac muscles are involuntary .... Skeletal muscles are voluntary .
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.
Different kind of muscles?
Cardiac, skeletal, smooth Cardiac-heart muscle, helps it pump Skeletal-helps you move along with bones Smooth- lines digestive system, blood vessels, involentary processes
How do smooth muscles and sphincters keep food moving in one direction throughout the digestive system?
by peristalsis which is the rhythmic, involuntary contraction of the smooth muscles in the walls of digestive organs.
What muscle does the digestive tract use when digesting food?
It is 'lined' by many muscles at many points, including circular muscles, longitudinal muscles etc. No single muscle, or single type of muscle, lines it.
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.
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.
What are some examples of the digestive muscle?
The digestive system comprises of organs that work together in order to ensure that food is properly processed through the body. Examples of such organs include the stomach and the intestines.
What medical condition has peristaltic contractions as one of its symptoms?
Peristaltic contractions are defined as the contraction of smooth muscles that moves food through the digestive system. In some cases, a medical condition can lead to spasms in these muscles causing pain or difficulty in swallowing. A few of the more common causes include pyloric stenosis and an intestinal obstruction.
What are 2 types of movements produced by contractions of the muscularis externa?
The two types of movements produced by contractions of the muscularis externa are peristalsis, which is a coordinated contraction and relaxation of circular and longitudinal muscles to propel food along the digestive tract, and segmentation, which involves the mixing and churning of food within a specific region of the digestive tract for digestion and absorption.
