Q

Function of body cavities

A

Confined space within the body that contain original organs: they serve to protect, separate, and support organs. They allow movement, separate functions, limit infection.

Q

What are serous membranes?

A

Line body cavities not open to exterior and covers organs.
Epithelium is called mesothelium (simple squamous) , CT = areolar
Secrete serous fluid- a thin, watery, lubricant so organs can move easily
