Alveolocytes Respiratory

Article "Respiratory alveolocytes"

Respiratory alveolocytes (also called squamous alveolocytes, alveolar respiratory cells, or covering cells) are thin, flat cells lining the alveoli of the lungs. They play a key role in gas exchange, ensuring rapid diffusion of oxygen from the pulmonary alveoli into the blood and carbon dioxide in the opposite direction.

Respiratory alveolocytes have a large surface area to maximize the area for gas exchange. Their cytoplasmic membrane contains a large number of channel proteins that allow oxygen and carbon dioxide to pass through the membrane along a concentration gradient. In addition, these cells secrete surfactant, a surfactant that reduces surface tension in the alveoli and prevents them from collapsing during exhalation. Thus, respiratory alveolocytes play a key role in maintaining normal gas exchange and lung function.



Airway alveocytes are cells that are found in the lungs and perform an important function in the breathing process. They are responsible for filtering the air and ensuring the supply of oxygen to the blood. Without them, breathing would be impossible.

An alveocyte is a type of cell that is found in lung tissue and is responsible for producing mucus. This is very important for protecting lung tissue from infection and
