What else can I help you with?
Muscular contractions of digestive tract?
this is called Peristalsis
What is the posterior opening of the digestive tract in a fetal pig?
The posterior opening of the digestive tract in a fetal pig is called the anus. It is the terminal end of the gastrointestinal system where waste material is expelled from the body. The anus is located at the posterior end of the pig, opposite to the mouth which is at the anterior end.
Where does the ventral nerve cord encircle the digestive tract and join with the brain in a grasshopper?
In a grasshopper, the ventral nerve cord encircles the digestive tract at the anterior end, where it connects to the brain. This connection occurs in the head region, specifically around the esophagus, forming a structure known as the subesophageal ganglion. This arrangement allows for coordinated control of the nervous system and digestive functions.
What are muscular movements along digestive tract?
Peristalsis. This process moves ingesta along the digestive tract.
What type of muscular contraction breaks foods into sections in the intestine?
Apex question, answer removed, copyright violation
What are the outpockets of an anterior digestive tract that may develop into respiratory structures?
The outpockets of an anterior digestive tract that may develop into respiratory structures are called respiratory diverticula. These diverticula are found in organisms like insects and some mollusks, where they eventually form into structures like tracheae or lungs for gas exchange.
What tissue is the digestive system made of?
The digestive system is primarily made up of muscular tissue, connective tissue, epithelial tissue, and nervous tissue. Muscular tissue helps with movement of food along the digestive tract, connective tissue provides support and structure, epithelial tissue lines the inner surface for absorption and secretion, and nervous tissue controls and coordinates its functions.
The third layer of the digestive system consist of what?
The third layer of the digestive system is the muscular layer, known as the muscularis externa. It is responsible for peristalsis, which is the contraction and relaxation of muscles to move food through the digestive system. The muscular layer helps mix and propel food along the digestive tract for digestion and absorption.
What is muscular waves that move materials along the digestive tract?
Peristalsis. The process of peristalsis begins in the esophagus when a bolus of food is swallowed.
What part of the brain assists the digestive system by moving food through the digestive tract?
The brain controls many hormonal and muscular processes of the digestive system. The digestive system, in turn, provides the brain with nutrients needed for its functions.
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.
What is the last part of the digestive tract?
The anus is the last part of the digestive tract.
