This cavity forms in the region of the heart the rudiment of the pericardial cavity.
The septum between the pericardial cavity and the body cavity is attached on its dorsal aspect to the liver.
The horizontal septum forms, as is obvious from the above description, the dorsal wall of the pericardial cavity.
The pericardial cavity is separated from the peritoneal cavity by a thick muscular wall against which the liver abuts.
The pericardial funnel leads into a glandular section of the organ, the lining cells of which are filled with concretions.
Autopsy (dog 31): Lungs congested; heart filled with blood and contained small amount of blood-stained fluid in pericardial sac.
pericardial cells: specialized cells, which lie along both sides of the heart, and whose function it is to purify the blood.
pericardial fluid somewhat increased, both ventricles moderately dilated, the right somewhat hypertrophic.
The heart is thus covered by the pericardial sac, but is not contained inside its cavity.
Collect a sample of pericardial fluid in a pipette for microscopical and cultural examination.
