The surface tension of water is due to the cohesive forces between water molecules at its surface. Similarly, the pleural serous membranes have a thin layer of liquid that creates surface tension to help maintain the lungs' position in the chest cavity and facilitate smooth lung movement during breathing. This surface tension plays a crucial role in preventing lung collapse.

What keeps the visceral and parietal pleural membranes in contact with each other?
The visceral and parietal pleural membranes are kept in contact by a thin layer of pleural fluid that fills the pleural cavity, creating surface tension. This fluid allows the membranes to slide smoothly over each other during respiration while preventing them from separating. Additionally, the negative pressure within the pleural cavity helps maintain the adhesion between the two layers.
Why is ther a film of liquid in the pleural cavity?
The film of liquid in the pleural cavity, known as pleural fluid, serves several important functions. It lubricates the surfaces of the pleurae (the membranes surrounding the lungs), allowing for smooth movement during respiration. Additionally, this fluid helps maintain surface tension and assists in keeping the lungs expanded against the chest wall. It also plays a role in immune defense and fluid balance within the thoracic cavity.
Is surfactant a problem in the pleural cavity?
Surfactant is a fluid secreted by alveolar cells in the lungs to reduce surface tension and prevent collapse. Surfactant is not typically present in the pleural cavity, and its presence there could indicate a medical issue such as lung injury or infection.
How is polarity related to surface tension?
Polarity is related to surface tension because it creates an imbalance in charge distribution at the surface of a liquid. This imbalance results in stronger intermolecular forces at the surface, leading to a cohesive force that resists external forces and causes the liquid to form a distinct surface. Substances with higher polarity generally exhibit higher surface tension due to the stronger intermolecular attractions present.
Does the pH of water remain exactly neutral because of the high surface tension of water?
The pH of water can remain neutral (pH 7) due to its ability to self-ionize, forming equal amounts of H+ and OH- ions. Surface tension is a property related to the cohesive forces between water molecules and does not directly affect the pH of water.
The force that tends to hold the visceral and parietal pleural membranes together?
surface tension.

Additionally, the negative pressure within the pleural cavity helps maintain the adhesion between the two layers.
What are the factors for holding the lungs to the thorax wall?
Surface tension from pleural fluid, positive pressure, and atmospheric pressure on the thorax.

What is pleural linkage?
There are 2 types of pleura in the thoracic cavity. Visceral pleura which covers the lungs and parietal pleura which covers the inner surface of the thoracic cage. These 2 pleurae form a sac which encases the lungs, the surface tension of the fluid links the lungs and thoracic cavity together aka pleural linkage, which allows the lungs and thorax to operate together as one unit.
What holds the visceral and parietal membranes together?
Surface Tension is technically what hods the membranes together. Not sure how technical you are going.
Why does surfactant reduce surface tension?
It prevents a pleural friction rub. Its like a lubricant for the lungs to move up and down without any friction.

What is surface tension.?
Surface tension is defined as the elasticlike force that exists at the surface.
Why is that needle floats in water?
Surface Tension ~ see related link below .
Is surface tension is extensive property?
No, surface tension is an intensive property because it does not depend on the amount of the substance present. It is a property that is related to the structure and composition of the surface of the liquid.
