coelom's Usage Examples:

The cavity of the latter is coelom.

The cavity of the former has nothing to do with coelom.

In this worm the ventral blood-vessel is so swollen as to occupy nearly the whole of the available coelom.

It has been asserted (and denied) that the cellular rod which is known as the "Heart-body" (Herzkorper), and is to be found in the dorsal vessel of many Oligochaeta and Polychaeta, is formed of cells which are continuous with the chloragogen cells, thus implying the existence of apertures of communication with the coelom.

With a few exceptions among the Polychaeta the vascular system is always present among the Chaetopoda, and always consists of a system of vessels with definite walls, which rarely communicate with the coelom.

Several forms of cells float freely in the fluid of the coelom.

It is therefore a haemocoel, the coelom of the developed insect being represented only by the cavities of the genital glands and their ducts.

In another sense also the coelom is not a closed cavity, for it communicates in several ways with the external medium.

Thus the nephridia, in this case at least, are a part of the coelom and are not shut off from it by a layer of peritoneum, as are other organs which lie in it, e.g.

The body wall of the Chaetopoda consists of a "dermo-muscular" tube which is separated from the gut by the coelom and its peritoneal walls, except in most leeches.

coelom's Meaning':

a cavity in the mesoderm of an embryo that gives rise in humans to the pleural cavity and pericardial cavity and peritoneal cavity
