Spongocoel, literally 'sponge cavity'.
The sponges are Acoelomates. That is they don't have coelom or body cavity.
A flagellated cell that sweeps water through a sponge's body is called a choanocyte. Choanocytes have a flagellum that creates a current to bring water through the sponge's pores, allowing for filter feeding and gas exchange to occur within the sponge's body.
Choanocyte (collar cells) are any of the flagellated cells located in the body cavity of a sponge. They surround the base of the flagellum. The function of these cells is to maintain the flow of water through the body of the sponge.

No, sponges do not have a backbone. They belong to a group of simple animals called Porifera, which lack true tissues and organs, including a backbone. Sponges are simple multicellular organisms with a porous body structure that allows water to flow through them for feeding.

The two sponge-like organs in the thoracic cavity are the lungs. They are responsible for the exchange of oxygen and carbon dioxide during the process of breathing. The lungs are located on either side of the heart within the chest cavity.
The brain and the spinal cavity are located in the dorsal body cavity.
A sponge doesn't have a body temperature, because a sponge doesn't have a body. But how warm or cold you put the sponge under water or any liquid is the temperature of the sponge.
Pisces or fish have true internal body cavity.
