The lung is the necessary link in transporting oxygen from the air to the blood. In this process, the pulmonary capillaries provide the critical air-blood interface. The thinness of the pulmonary capillary wall is conducive to fluid leakage and pulmonary edema, which could impair oxygenation of the blood. The pulmonary capillaries must maintain adequate perfusion, but it is essential that the p...
