Question

Why do serous membranes occur in pairs?

Answer 1

Answer:

The parietal layer lines a specific portion of the ventral body cavity. It folds in on itself to form the visceral layer, which covers the outside organs of that cavity (like the stomach. ...  Serous fluid allows organs to slip past each other without generating friction.

Answer 2

The Serous Membrane is known to have layers of simple squamous epithelium. It occur in pairs because by pairing, it helps the serious membrane to perform its function as the two moist layers make it even easier for organs to move without friction.

• The Serous Membrane as a layer of simple squamous epithelium on a thin layer of areolar connective tissue. It often occur in pairs called parietal and visceral layer.

• The parietal layer is wall layer and helps lines a some key portion of the wall of the ventral body cavity while the visceral layer helps to lines organs in the cavity

Conclusively, we can say parietal and visceral moist layer helps in create lines in the body cavity.
