Serous membranes line certain cavities within the anterior body cavity. <br> a. true <br> b. false
crimeas [40]

Serous membranes line certain cavities within the anterior body cavity. This statement is FALSE.

Serous membrane, also known as serosa in anatomy, is a silky tissue membrane made of mesothelium that lines the interior of bodily cavities and their contents. It secretes serous fluid to permit greased sliding motions between friction surface. Organs housed in body cavities that don't open up to the outside are covered by serous membranes that line the body cavities. The epithelium secretes a thin coating of serous fluid that coats serous membranes.

An indication of a serous membrane is the lining of the thorax. The pleura is the name for the serous membrane found in the thorax. The visceral pleura, the innermost layer, is on the lungs, whereas the parietal pleura, the outermost layer, is on the interior layer of the thorax.
