Question
The pleural membrane has two main functions. One function is the keep an air tight seal within the
thoracic cavity and another is to secrete slippery fluid into the space around the lungs and thus
reducing friction during breathing movements. The serous membrane on top of the diaphragm is
only one of the membranes secreting slippery fluid into the thoracic cavity. The lungs also have a
serous membrane to secrete a slippery fluid. For this reason the two membranes are given specific
names. The membranes that line the body cavities are called parietal membranes while the
membranes on the organ itself are called visceral membranes.
Examine the lungs on the cadaver. Is this visceral pleural membrane directly attached to the lungs
or does it loosely fit around the lungs?
