The thin tissue that holds the organs together in the body cavity of a frog is called mesentery.
coelomates
Frogs have a different anatomy then many other animals. The large organ that covers most of their body cavity is the liver.
yes, I think it's called coelom. An organism with a true body cavity is called a eucoelomate. This means that the body cavity exists between the inner layer of mesoderm and the outer layer of mesoderm. A pseudocelomate kind of has a body cavity but it is the space between the endoderm and mesoderm. This is not a true body cavity because it is not mesoderm on mesoderm.
they are coelomates, which means that their body cavity is fully lined with the mesoderm.
No, actually. A rooster's testicle is actually INSIDE his body cavity, unlike mammals. But being inside his body cavity does not make him infertile, no. Birds have the kind of sperm that grow and thrive from being inside the body cavity, unlike mammals where if the testes were inside their body cavity, this would render them infertile.
Epithilial Tissue Lines animal's body Cavity, they can be further subdivided into different types of Epithelial Tissue, depending on what they line
abdominal cavity
Protists do not have a body cavity.
Arthropods have an internal body cavity called a hemocoel which bathes the internal organs in nutrients, and is a component of their open circulatory system.
