The atria (singular atrium)

atria
The cavities of the brain are called ventricles. These ventricles contain Cerebro Spinal Fluid to help aid in the filtration of the blood.
The space medial to the pleural cavities is called the mediastinum. It contains vital structures such as the heart, major blood vessels, esophagus, and trachea.
Yes, but it is not the same as mammal blood. Insects have a clear to yellowish fluid, called haemolymph, which fills their body cavities and this is the equivalent to our blood.
No, endothelium lines the inner surfaces of blood vessels, not internal cavities like the pleural and peritoneal cavities. The lining of internal cavities is typically composed of a different type of epithelial cells called mesothelium.
The reticuloendothelial cellslocated in the blood cavities of the liver are calledKupffer cells.
Venules

Cavities that are filled with blood and help drain cerebrospinal fluid in the brain are called the arachnoid granulations. These structures play a key role in maintaining the balance of cerebrospinal fluid in the central nervous system.
Mesothelium and endothelium are types of epithelium tissue. Mesothelium lines the body cavities and endothelium lines primarily the circulatory system.
Bone marrow cavities contain marrow that produces red blood cells, white blood cells, and platelets. It also lightens the bones.
