The lung is "held" to the thoracic wall by a vacuum or a "potential" space. The thoracic wall has a thin membrane attached to it called the parietal pleura. The lung also has this membrane attached to it but is called the visceral pleura. The two pleura touch each other and slide against each other but are not attached. There is no space between them in the same way there is no space between the sides of a balloon when you suck out the air. If you are stabbed in the chest, an opening is created and air rushes in the hole. The "potential" space becomes an actual space as the lung collapses (a condition called a pneumothorax).

What is the pleural membrane?
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.
What is the force responsible for normal expiration?
Elastic recoil of lungs and thoracic wall
What membranes are associated with the lungs and the thoracic walls?
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.
What is the thoracic pleura?
The inner lining of your chest wall against which the lungs lie and move.
What is the function of the pleura membrane in a pig?
The pleural cavity (with an outside pleural membrane) surrounds both the pleural and pericardial cavities. The fetal pig tissues are thin and easily cut. The parietal pleura is a serous membrane which surrounds the lungs. It is like a thin film, and can be somewhat difficult to remove and isolate. The parietal pleura is on the thoracic cavity wall.
Does plant cells need a cell membrane?
Yes plant cells need a cell membrane. In addition to the cell membrane they also have a cell wall. Animal cells however do not have a cell wall but merely a membrane. A cell is not able to live without a membrane as it holds the organelles and cytoplasm in place.
What holds the cell membrane together?
yo Mama lol jk the chemical that holds molecules togehter is chemical bond YOUR WELCOME
What happen if plant cell has no cell membrane?
It would be very messy. The cell membrane is what "holds the goo in". Without it, the plant would be a puddle. -Well the cell wall holds the plant cell together, the loss of membrane wouldn't change the overall shape of the cell
What cell is inside the cell wall?
In plant cells, which contain cell walls, there is a cell membrane inside the cell wall. Inside the membrane is the cytoplasm which holds all the cell's vital organelles.
What holds the plant and animal cell together?
A plant cell has a cell wall and a cell membrane to keep its shape, an animal cell has a cell membrane
What is the cytoplasum?
The cytoplasum is on the inside of the cell wall, or membrane. The cytoplasum holds all the organelles.It's where cell proteins are created(Ithink).
Does the nucleus of a cell protect the cell?
The nucleus only holds the DNA. the cell membrane protects animal cells. the cell wall and cell membrane protects plant cells
