Pulmonary Membrane

The pulmonary membrane (LM) is a morphological formation that separates the lumen of the pulmonary alveoli (PA) from the lumen of the capillaries in the lungs. The LM consists of endothelial cells, two basement membranes and squamous alveolar epithelium. It also contains a layer of anti-atelectatic factor, which helps maintain lung function and prevents atelectasis.

The LM is an important part of the lungs as it regulates gas exchange between air and blood. When air enters the lungs, it passes through the PA and comes into contact with endothelial cells, which secrete an antiatelectatic factor. This factor helps maintain the alveolar epithelium in a healthy state and prevent its atelectasis.

In addition, LM plays an important role in the immune system of the lungs. LM endothelial cells express a variety of molecules, including adhesion molecules and cytokines, that are involved in immune responses in the lung. These molecules help regulate inflammation in the lungs and prevent the development of various lung diseases.

However, if the LM is damaged or compromised, it can lead to various pulmonary diseases such as asthma, emphysema and chronic bronchitis. Therefore, it is important to maintain the health of the LM and prevent its damage.

Pulmonary membrane: Description and functions

The pulmonary membrane is a complex morphological formation in the lungs that separates the lumen of the pulmonary alveoli and capillaries. It is an important component of the alveolar system and plays a key role in gas exchange and pulmonary respiration. In addition, pulmonary
