surfactant is a phospholipid that reduces
Pulmonary Surfactant. Surfactant is a complex substance containing phospholipids and a number of apoproteins. Surfactant reduces surface tension throughout the lung, thereby contributing to its general compliance. Pulmonary surfactant is a surface-active lipoprotein complex formed by type II alveolar cells.ottom left: the phospholipid 1-palmitoyl-2-oleoylphosphatidylcholine (POPC).
