By rhythmic movements called peristalsis. They are wavelike contractions of smooth muscle that propel food through the GI tract.
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.
Peristalsis is a series of involuntary smooth muscle contractions along the walls of the digestive tract that move food through the digestive tractperistalsis
a spasm
Tetany is the term for the muscle contractions that may be caused by hypoparathyroidism.
the cardiac sphincter opens involuntarily during peristalsis, which is the process of wavelike muscle contractions of the alimentary tract that moves food along the oesophagus down to the stomach. :)
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.
