n.
1. See coelom.
2. Any of the cavities of the body that adjoin external orifices, such as the mouth or rectum.

Major body cavities

body cavity

Any space in the body that does not freely communicate with the outside. Body cavities are covered with specialised lining cells—e.g., mesothelial cells in the pericardium, peritoneum and pleura.

Body cavity types
• Major—Pericardial, pleural, peritoneal, cerebrospinal. 
• Minor—Amniotic, anterior chamber of the eye, cul de sac, hydrocele, oral cavity, synovial, vitreous.

CAVITIES OF THE BODY
1. Any hollow space within the body. See: illustration
2. A hidden body space that is accessible from the outside, e.g., rectum or vagina. Referred to in “body cavity search for contraband”.
3. Derivatives of the coelom, i.e., the pericardial, peritoneal, and plural sacs. See: coelom

body cavity

the space within the body of most animals in which the gut and various organs are suspended. It normally contains fluid and is derived embryologically in different ways in different groups of animals. Absent in PLATYHELMINTHS and NEMERTINE worms, it is derived from the COELOM in vertebrates and from the HAEMOCOEL in arthropods and molluscs. It occurs as an intercellular space in nematode worms.

body

1. the trunk, or animal frame, with its organs.
2. the largest and most important part of any organ.
3. any mass or collection of material.

body surface area (BSA)
the total surface area of the body. Used to calculate drug dosages, particularly in the use of toxic drugs such as those used in cancer chemotherapy. This minimizes errors introduced by variations in distribution, metabolism and excretion of the drug. Several equations can be used to express the area, based on body weight, but conversion tables are usually used. See Table 21.
