What are the two major groups of body muscles in annelids called?
Circular and Longitudinal muscles.
Which organ in the digestive system moves food from the mouth to the stomach?
The esophagus is the digestive organ that moves food from the mouth to the stomach. No digestion, only transport, happens in the esophagus.
What is the function of the Longitudinal muscles in the GI tract?
The circular muscle layer prevents food from traveling backward and the longitudinal layer shortens the tract. By Ah Mok
How are the functions of longitudinal and circular muscles in annelids different?
The longitudinal and circular muscles are antagonistic. This means that they are paired and while one contracts, the other relaxes.
What is the medical term meaning failure of the muscles of the lower esophagus to relax during swallowing?
The medical term for the failure of the muscles of the lower esophagus to relax during swallowing is called achalasia. This condition can cause symptoms such as difficulty swallowing, chest pain, and regurgitation of food. Treatment options may include medications, dilation of the esophagus, or surgery.
The esophagus contains both smooth and skeletal muscle fibers?
The esophagus has two types of muscles. The upper third of the esophagus is composed of striated muscles, while the lower third contain smooth muscles. The muscles in the middle are a mixture of both striated and smooth.
The muscular action that propels food through the esopahgus is called?
Peristalsis is a symmetrical contraction of muscles which propagates in a wave down the muscular tube, more specifically the esophagus. In humans, peristalsis is found in the contraction of smooth muscles to propel contents through the digestive tract.In much of the gastrointestinal tract, smooth muscles contract in sequence to produce a peristaltic wave which forces a ball of food (called a bolus while in the esophagus and gastrointestinal tract and chyme in the stomach) along the gastrointestinal tract. Peristaltic movement is initiated by circular smooth muscles contracting behind the chewed material to prevent it from moving back into the mouth, followed by a contraction of longitudinal smooth muscles which pushes the digested food forward.
How many muscles does the esophagus have?
12
What ringed muscles push food to the stomach?
Esophagus
What Does peristalsis have to do with the esophagus?
Smooth muscles in the wall of an esophagus move food downward with a squeezing action. These waves of muscle contractions move food through the entire digestive tract. This process is called peristalsis.
How is food moved along the asophagus?
the asophagus by, the muscles in the (Gullet) by contractions in the gullet. i think ?
Contraction of an earthworm's longitudinal muscles?
