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.

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.
