Does surfactant promote elastic recoil of the lungs?

No, surfactant does not promote elastic recoil of the lungs.

Surfactant is a substance that reduces surface tension in the lungs. It helps to keep the alveoli open and prevents them from collapsing. Elastic recoil is the property of the lungs that allows them to snap back after they have been stretched. It is caused by the elastic fibers in the lung tissue.
