A gastrovascular cavity in a jellyfish serves as both a digestive and circulatory system. It is a central cavity where food is digested and nutrients are distributed throughout the jellyfish's body. The cavity is lined with cells that secrete digestive enzymes to break down food, allowing for nutrient absorption. This structure is crucial for the jellyfish's simple body plan, as it lacks a complex circulatory system.

What invertebrate has a gastrovascular cavity?
The hydra is a classic example. See link below for more information.
What is a gastrovascular cavity?
A gastrovascular cavity is a digestive chamber with a single opening, found in simple animals like jellyfish and flatworms. Food is ingested through the opening, where it is broken down and absorbed by the cells lining the cavity. Waste is expelled through the same opening.
How jellyfish eats?
They digest food using the gastrodermal lining (a sort of acidic membrane) of the gastrovascular cavity (a hole on its underside), where nutrients are absorbed.
Where is gastrovascular cavity found?
The gastrovascular cavity is found in certain simple organisms, primarily in the phylum Cnidaria, which includes jellyfish, corals, and sea anemones. It serves as both a digestive and circulatory system, allowing for the distribution of nutrients and the removal of waste. Additionally, it is present in some flatworms, providing a similar function in these organisms.
How much openings does a gastrovascular system have?
A gastrovascular system, found in organisms like jellyfish and flatworms, typically has one opening that serves both as a mouth and an anus. This single opening allows for the intake of food and the expulsion of waste, facilitating a simple digestive process. The gastrovascular cavity aids in nutrient distribution throughout the organism's body.
What is the tissue that lines the gastrovascular cavity?
The tissue that lines the gastrovascular cavity in organisms like cnidarians is called gastrodermis. It is responsible for digestion and absorption of nutrients from the food.
What does the mouth of the cnidarian open into?
The mouth of a cnidarian, such as a jellyfish or sea anemone, opens into a central body cavity called the gastrovascular cavity. This cavity serves both digestive and circulatory functions, as it allows nutrients to be absorbed and distributed throughout the organism's body.
Does a jellyfish have a two way digestive system?
No, a jellyfish does not have a two-way digestive system. Instead, it has a simple gastrovascular cavity with a single opening that serves both as a mouth and an anus. Food enters the cavity for digestion, and waste is expelled through the same opening. This type of digestive system is characteristic of simpler organisms.
Is a gastrovascular cavity a digestive tract with two openings - a mouth and anus?
No, a gastrovascular cavity only has one opening. Only an alimentary canal features a mouth and anus.
One difference between a gastrovascular cavity and a complete digestive tract?
A gastrovascular cavity is a digestive sac with only a single opening. A complete digestive tract (otherwise known as an Alimentary canal) has two openings (a mouth and anus) between its digestive tubes unlike the gastrovascular cavity in which food is ingested and eliminated through the same opening (example would be hydra)
A digestive chamber with one opening is called?
gastrovascular cavity
What is the space inside coelenterates?
It is called the Coelenteron or gastrovascular cavity.
