What else can I help you with?
The ability of the GI tract to mix and move material along its length is called?
peristalsis, which is the coordinated muscle contractions that propel food and liquids through the gastrointestinal tract.
What does the GI tract stand for?
The GI tract stands for the gastrointestinal tract, which is a complex system responsible for the digestion and absorption of food. It includes various organs such as the mouth, esophagus, stomach, small intestine, large intestine, and anus. The GI tract plays a crucial role in breaking down food, absorbing nutrients, and eliminating waste from the body.
What comes in and out of the gi tract?
Food and fluids go in...Feces and fluids come out... The GI tract is an overall workhorse to convert ingested food and fluid to energy and stored energy, as well as get rid of wastes.
What body system contains the GI tract?

It is a flap of tissue that covers the trachea during swallowing to prevent food and liquids from entering the airway. The first true sphincter in the GI tract is the lower esophageal sphincter, which regulates the passage of food from the esophagus into the stomach.
What does movement mean in reference to digestion?
Movement in reference to digestion refers to the muscular contractions that help propel food through the digestive tract. This movement, known as peristalsis, helps mix food with digestive enzymes and facilitate absorption of nutrients in the small intestine. Inadequate movement can lead to issues like constipation or slowed digestion.
What are the two important ways in which the GI tract works?
Gastrointestinal tract have digestive secretions to digest the food and peristaltic movements to propel the food forwards.
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
Does the myenteric nerve plexus provides the major nerve supply to the GI tract wall and controls GI motility?
Yes, the large myenteric nerve plexus lies between the cirular and lomgitudinal muscle layers of the muscularis externa. Enteric neurons of this plexus provide the major nerve supply to the GI tract walls and controls GI tract motility. (page 778of Marieb, A&P 3rd edition)
How do tigers defecate?
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules and out from the bowel
What layer of GI tract is responsible for forming sphincters?
The muscularis layer of the gastrointestinal (GI) tract is responsible for forming sphincters. These sphincters help regulate the passage of food and fluids through different parts of the GI tract, such as the lower esophageal sphincter, pyloric sphincter, and anal sphincter.
What is mucosa's fragility?
Mucosa can be found in the lining of the GI tract and friable is a term used to described the amount of degradation experienced in the GI tract. The Mucosa of the GI tract aids in the degradation of food in the body.
