Membrane that lines ventral cavities
Two layers of the serous membrane

pericardium and pleura
Pericardium
Subdivision of the Thoracic cavity, a serous membrane around the heart
Three membranes of the pericardium (heart)
Parietal and visceral pericardium, Pericardial cavity
Parietal pericardium
outer layer of the pericardium
Pericardial cavity
