alveolinen

Alveolinen is a term sometimes used in scientific literature, particularly in older or specialized contexts, to refer to alveoli, which are the tiny air sacs in the lungs responsible for gas exchange. These microscopic structures are crucial for respiration, allowing oxygen to enter the bloodstream and carbon dioxide to be removed. The wall of each alveolus is extremely thin, composed of a single layer of epithelial cells, and is surrounded by a dense network of capillaries. This intimate proximity facilitates the efficient diffusion of gases between the air in the alveoli and the blood in the capillaries. The lungs contain millions of alveoli, providing a vast surface area for this vital process. Conditions affecting the alveoli, such as pneumonia or emphysema, can significantly impair lung function and breathing. While the term alveolinen is not as commonly used today as "alveoli," understanding its historical context can be helpful when encountering older scientific texts. The primary function of alveoli remains unchanged, highlighting their fundamental importance in mammalian respiration.
