keuhkoparenkymästä
Keuhkoparenkyma refers to the functional tissue of the lungs, excluding the supporting structures. It is primarily composed of alveoli, which are tiny air sacs where gas exchange occurs, and the surrounding capillaries. This delicate network is responsible for taking in oxygen from inhaled air and releasing carbon dioxide from the blood. The structure of the parenchyma is highly specialized to maximize the surface area available for diffusion, allowing for efficient respiration.
The bronchioles, small airways that branch from the bronchi, lead to the alveoli within the parenchyma. These
