Mucous glands secrete mucin. The mucin combines with water to produce a thick sticky secretion in the lungs, which the body attempts to dispel .
Each of a pair of serous membranes lining the thorax and enveloping the lungs
The pleural membrane is a double-layered serous membrane found in the thoracic cavity. The outer layer is called the parietal pleura and lines the thoracic wall, and the inner layer is called the visceral pleura and covers the lungs. The membranes produce lubricating serous fluid that causes them to adhere closely to one another. This holds the lungs to the thoracic wall allowing easier movement during breathing.
The two pleural membranes are the visceral pleura and the parietal pleura. The visceral pleura is the innermost layer that covers the surface of the lungs, while the parietal pleura lines the chest cavity. These membranes create a fluid-filled space called the pleural cavity, which helps to reduce friction and allows for smooth movement of the lungs during breathing.

Lungs A +
Tumor is in the lungs and membranes around the lungs.
the lungs are protected with a db layer serous membrane. 1: is the superficial layer called the Parietal pleura that line the walls of the thoracic cavity. 2: The deeper layer is the visceral pleura, which cover the lungs themselves. In between the both membranes is a small space(cavity)filled with pleurisy to reduce friction.
The snot comes from the lungs and mucus membranes. Mucus is meant to protect the lungs and membranes and contains antibodies that are designed to help kill disease.
Its function is to take dust out of the air as it passes through your nostrils to the lungs. That's why it is sticky.
Areolar tissue in the lungs forms part of the lamina propria, an underlayer of the serous membranes (pleura) of the lungs.
pleuritis
They are called the pleura.
