label: Hyaline membranes
label_lc: hyaline membranes
description: "Hyaline membranes are homogeneous eosinophilic material composed of cellular debris, plasma proteins, and surfactant plastered against alveolar ducts and alveolar walls. The hyaline membranes are deposited along the walls of the alveoli, where gas exchange typically occurs, thereby making gas exchange difficult."
