alveolar cells|Type I and Type II

Distinguishing these cells is significant in the pathophysioloy of Acute Respiratory Distress Syndrome. The type I cell is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and relatively devoid of organelles; these plates represent the gas exchange surface in the alveolus. Type I cells line more than 95% of the alveolar [...]

Acute Respiratory Distress Syndrome- Definition & Pathophysiology

Acute Respiratory Distress Syndrome [ARDS] is an acute condition characterized by bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence for cardiogenic pulmonary edema. In this condition, the small blood vessels leak leading to fluid bluid up in the alveoli. This is described as diffuse alveolar damage (DAD) and lung capillary endothelial injury. [...]
