How does an earthworm's circular and longitudinal muscles aid in movement?
Their short bristles or hairs are a great aid to them as well as the peristalsis of their locomotion.
What uses peristalsis and pepsin to aid digestion?
The stomach uses peristalsis and pepsin to aid digestion.
What is peristalsis and how does it aid in digestion?
Contraction of smooth muscles to carry contents through the digestive tract. Examples are in the esophagus and small intestine.
What is the function of peristalsis?
It contracts and relaxes your muscles to aid in the digestion of food in the intestines and stomach.
What chemicals aid in the contraction of muscles?
Acetylcholine

How is food moved through the digestive tract?
A number of things aid in the movement of food through the gut. Peristalsis is a huge contributer, it is small muscle contractions that occur throughout the digestive system. It help moves food down the esophagus. The cardiac sphincter then allows food to enter the stomach where food again is mixed and moved by peristalsis. Food sits in the reservoir of the stomach as chyme(the mixed up mush of the food we ate) where finally the pyloric sphincter allows it into the small intestine without backing up. Again peristalsis works to push it through the intestines to eventually be excreted as waste.
Name the muscle known as the anitgravity muscle what three muscles combine to form this muscle?
Oesophagus. Supported by superior, middle and inferior pharyngeal constrictor muscles, which aid peristalsis and force a bolus of food inferiorly towards the stomach - even while the subject is upside-down!! Brought to you by Ash.
What are paristalsis?
Peristalsis is a wave-like series of muscle contractions in the body, like in the esophagus and intestines, designed to aid the movement of solids through the digestive system.
What is the function of the Instercostal muscles?
Aid in respiration - usually deeper breathing
