An air or fluid filled space is called a cavity. It can be found within the body, such as the nasal cavity or the pleural cavity within the chest. It can also refer to spaces in rocks, soil, or structures.
The thin fluid-filled space in the chest between the two pleural layers is called the pleural cavity. This space helps the lungs expand and contract during breathing by reducing friction between the layers of the pleura.
A coelom is a fluid-filled body cavity found in many animals, including humans. It serves to cushion and protect internal organs, as well as providing a space for them to move independently of the body wall. This cavity is lined by a membrane called the peritoneum.
The fluid-filled bag of thin tissue that develops around the embryo is called the amniotic sac. It helps protect and cushion the developing embryo/fetus during pregnancy.

A blastocoele is the fluid-filled cavity in the blastula.
An air or fluid filled space is called a cavity. It can be found within the body, such as the nasal cavity or the pleural cavity within the chest. It can also refer to spaces in rocks, soil, or structures.
A tendon sheath is a fluid-filled cavity that surrounds a tendon to reduce friction and allow smooth movement. It is lined with synovial cells that secrete a lubricating fluid called synovial fluid.
No, coelomates do not have a body cavity. Coelomates have a fluid-filled cavity called a coelom that is lined with mesoderm. This cavity allows for the internal organs to be suspended and protected within the body.
The central cavity within the blastula is called the blastocoel. It is filled with fluid and is surrounded by a layer of cells called the blastoderm.
The abdominal cavity contains major body organs such as the stomach, liver, intestines, and kidneys. This cavity is lined with a membrane called the peritoneum and is filled with a fluid called peritoneal fluid to help protect and cushion the organs.

The fluid-filled cavity located in each hemisphere of the cerebrum is called the lateral ventricle. It is part of the ventricular system of the brain and plays a role in producing and circulating cerebrospinal fluid.
The vacuole is a fluid-filled membrane-surrounded cavity located inside a cell
Semicircular canals: are the fluid filled structures in the ear, which are involved in balance.
A body space or cavity in a mollusk is called a coelom. It is a fluid-filled cavity that surrounds the internal organs and provides support as well as a space for organ movement.
A blastocoel is the fluid-filled cavity in the blastula.
