Membranes in the Ventral Body Cavity

Visceral peritoneum

Covers most of the organs within the cavity

Visceral Pericardium

Covers the heart

Visceral Pleurae

Covers the lungs

Parietal Peritoneum

Covers the walls of the abdominopelvic cavity

Serous Fluid

Fluid secreted by both the Parietal and Visceral membranes, it is what separates the two layers. This fluid allows the organs to slide without friction across the cavity walls and one another as they carry out their routine functions.

Parietal Pericardium

Lines the Pericardial cavity

Parietal Pleurae

Lines the walls of the Thoracic cavity

Visceral Serosa

This layer covers the organ in the cavity. (The inner part of the double layer)

Parietal Serosa

This layer lines the cavity walls. (The outer part of the double layer)

Serosa (Serous Membrane)

This thin double-layered membrane covers the walls of the ventral body cavity and the outer surfaces of the organs.
