  2. Ventilation/perfusion ratio - Wikipedia

    en.wikipedia.org/wiki/Ventilation/perfusion_ratio

    This matching may be assessed in the lung as a whole, or in individual or in sub-groups of gas-exchanging units in the lung. On the other side Ventilation-perfusion mismatch is the term used when the ventilation and the perfusion of a gas exchanging unit are not matched. The actual values in the lung vary depending on the position within the lung.

    It folds back to form two layers, and each layer is called parietal pleura and visceral pleura. The pleural cavity refers to the area between the parietal and visceral pleura, and pleural fluid fills the pleural cavity to lubricate the pleural surface and provide surface tension. These functions ensure the safety of the lungs and proper ...
