Some of the endothelial cells lining the coelom are ciliated, the cilia keeping the corpusculated fluid contents in movement.
In the intestinal region the coelom is only present on the left side.
The existence of two renal organs in Patella, and their relation to the pericardium (a portion of the coelom), is important.
I, coelom of the first somite which carries the antennae and is in front of the mouth.
After the pericardium and pleurae have been separated off the remainder of the coelom becomes the peritoneum.
The kidney duct is seen running along the roof of the coelom on either side.
In both the cavity originally or immediately continuous with the coelom appears first in the funnel and grows backwards.
II, coelom of the second somite which carries the mandibles (hence deuterognathous).
Several forms of cells float freely in the fluid of the coelom.
When the pus escapes from the tubes into the coelom it sets up pelvic peritonitis.
coelom coe·lom or ce·lom or coe·lome (sē'ləm)
The cavity formed by the splitting of the embryonic mesoderm into two layers; in mammals it then forms into the peritoneal, pleural, and pericardial cavities.
The body cavity that forms from the mesoderm during the embryonic development of more complex animals. The coelom suspends the gut in fluid in the middle of the body, protecting it from gravity and allowing great increases in body size. The presence or absence of a coelom is important for the classification of animal phyla. See more at deuterostome, protostome.
