How are gastrovascular cavity and digestive tract alike?
The gastrovascular cavity is a structure found in primitive animal phyla. It is responsible for both the digestion of food and the transport of nutrients throughout the body. The cavity has only one opening to the environment. Food goes in and waste comes out that same opening, making it a two-way digestive tract.
How does the gastrovascular cavity and digestive tract differ in function?
(a) A gastrovascular cavity has a single opening through which food is ingested and waste is excreted, as shown in this hydra and in this jellyfish medusa. (b) An alimentary canal has two openings: a mouth for ingesting food, and an anus for eliminating waste, as shown in this nematode.
Is gastrovascular cavity digestive system?
The gastrovascular cavity is the primary organ of digestion and circulation in two major animal phyla: the Coelenterates or cnidarians (including jellyfish and corals) and Platyhelminthes (flatworms). The cavity may be extensively branched into a system of canals.
What is the difference between a gastrovascular cavity and a complete digestive tract quizlet?
A gastrovascular cavity or digestive sac has only one opening for food to enter and wastes to exit. A complete digestive tract is a one-way tube with two openings—a mouth at one end where food enters, and anus at the the end where wastes exit.
What is the meaning of digestive tract?
Listen to pronunciation. (dy-JES-tiv trakt) The organs that food and liquids travel through when they are swallowed, digested, absorbed, and leave the body as feces. These organs include the mouth, pharynx (throat), esophagus, stomach, small intestine, large intestine, rectum, and anus.
What is the function of digestive tract?
The principal functions of the gastrointestinal tract are to digest and absorb ingested nutrients and to excrete waste products of digestion. Most nutrients are ingested in a form that is either too complex for absorption or insoluble and therefore indigestible or incapable of being digested.
How are Gastrovascular and digestive tract different?
The key difference between gastrovascular cavity and alimentary canal is that gastrovascular cavity is a two-way digestive tract which has only one opening while the alimentary canal is a one-way digestive tract which has two openings. Based on the body plan, organisms can be primitive or advanced.
What is the function of the gastrovascular cavity quizlet?
Gastrovascular cavity is functions in both digestion and distribution of nutrients that has a single opening. Alimentary Canal is (digestive tube with mouth and anus) allows for more complete digestion of food.
Where is the digestive tract?
The digestive tract begins at the mouth and ends at the anus. It is like a long muscular tube, up to 10 metres long, with digestive organs attached along the way. A large reservoir of microbes, such as bacteria, live within the large intestine and, to a lesser degree, in vthe rest of the digestive system.
What is the difference between the digestive tract and the digestive system?
The organs that food and liquids travel through when they are swallowed, digested, absorbed, and leave the body as feces. These organs include the mouth, pharynx (throat), esophagus, stomach, small intestine, large intestine, rectum, and anus. The digestive tract is part of the digestive system.
What is the digestive system simple definition?
Listen to pronunciation. (dy-JES-tiv SIS-tem) The organs that take in food and liquids and break them down into substances that the body can use for energy, growth, and tissue repair. Waste products the body cannot use leave the body through bowel movements.
What is the function of the gastrovascular cavity?
The gastrovascular cavity is mainly involved in the digestion and circulation. The gastrovascular cavity is the primary organ of digestion in two major animal phyla: the Coelenterates or cnidarians (jellyfish, corals and flatworms).
What advantage does a one way digestive tract have over a gastrovascular cavity?
There are obvious advantages of such a system over a gastrovascular cavity, among them the fact that food moves in one direction through the tubular system, which can be divided into a series of distinct sections, each specialized for a different function.
What is the other name of digestive tract?
alimentary tract
The digestive tract is part of the digestive system. Also called alimentary tract and gastrointestinal tract.
How does the digestive tract work?
As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
What is another name for the digestive tract?
The digestive system is made up of the alimentary canal (also called the digestive tract) and other organs, such as the liver and pancreas. The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus.
What is the difference between digestive tract and digestive system?
What is the digestive system? The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
