Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems.
What else can I help you with?
What type of circulatory system does a jellyfish have?
A jellyfish does not have any circulatory vessels. They use diffusion as their means of circulation. They do not have a closed circulatory system.
Are jellyfish cold blooded animals?
Because box jellyfish, as with all other cnidarians, do not have blood, or a circulatory system, they can not be considered "cold-blooded." However, they are ectotherms whose body temperatures are equal to the temperature of the environment.
Does a jellyfish have a circulatory system?
no they use diffusion to circulate the cold blood. They have an open-circulatory system which means that the blood flows freely throughout the body
Why jellyfish is not an animal?
Jellyfish are, compared to mollusks, arthropods and vertebrates, very simple organisms. Jellyfish did not evolve a circulatory system, as they can perform gas exchange at their outer surfaces.
What type of circulatory systems do jellyfish have?
Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems.
What type of circulatory system does Phylum cnidaria have?
Phylum Cnidaria (e.g. jellyfish, corals) have an open circulatory system. This means that their circulatory fluid, called coelomic fluid, bathes their internal organs directly in nutrients and oxygen. There is no distinction between blood and interstitial fluid in an open circulatory system.
What does Phylum cnidaria have instead of a circulatory system?
Cnidarians have a hydrostatic skeleton, this means the body is supported by the liquid that fills it. They have a central cavity surrounded by two layers of tissue, the ectotherm and endotherm. The jellyfish has no circulatory system but a nervous system. It has some muscle fibers controlled by the network of nerves. IT has no brain to coordinate its reactions.
What is the circulatory system in the monkeys body?
closed circulatory system (double circulatory system)
How are the circulatory system and the circulatory system related?
They're both the circulatory system.
Do amphibians have an open circulatory system or a closed circulatory system?
Amphibians have closed circulatory system Closed
What are the body parts of the arteries?
The circulatory system
In which animals does oxygen reach all cells through the process of diffusion?
Flatworms and jellyfish don't have a circulatory system and in these animals, the oxygen is diffused through the cells.
