Surfactant is a complex substance containing phospholipids and a number of apoproteins. This essential fluid is produced by the Type II alveolar cells, and lines the alveoli and smallest bronchioles. Surfactant reduces surface tension throughout the lung, thereby contributing to its general compliance. It is also important because it stabilizes the alveoli.
Stagnant anoxia occurs when there is interference with the blood flow, although the blood and its oxygen-carrying abilities are normal. A common cause of general stagnant anoxia is heart disease or interference with the return of blood flow through the veins.
anemic hypoxia hypoxia due to reduction of the oxygen-carrying capacity of the blood as a result of a decrease in the total hemoglobin or an alteration of the hemoglobin constituents.circulatory hypoxia stagnant hypoxia. histotoxic hypoxia that due to impaired utilization of oxygen by tissues, as in cyanide poisoning. a type brought about by a reduction of the oxygen-carrying capacity of the blood because of a decrease in the complete blood counts or an alteration of the hemoglobin constituents. hypoxia, anoxic, n a type resulting from inadequate oxygen in inspired air or interference with gaseous exchange in the lungs.
