Membranes in the Ventral Body Cavity
• Serous Membrane or
Serosa
– Double layered
membrane that covers
the walls of the ventral
body cavity and outer
surface of the organs
– Parietal serosa and
visceral serosa
Membranes in the Ventral Body Cavity
• Parietal serosa
– The outer layer of the
serous membrane that
lines the cavity walls
Membranes in the Ventral Body Cavity
• Visceral Serosa
– The inner layer of the
serosa that covers the
organs of the ventral
body cavity
Membranes in the Ventral Body Cavity
• Serous fluid
– Separates the serous
membrane
– Thin layer of lubricating
fluid

• Umbilical Region
– Centermost region
– Surrounding the navel
Regions
• Epigastric Region
– Superior to the umbilical
region
– Epi = upon, above

Regions
• Hypogastric (pubic)
Region
– Located below the
umbilical region
