Large alveolar cells (alveolocyti magni) are one of the types of lung cells responsible for gas exchange in the body. They are large cells located in the epithelium of the alveolar walls and having a surface area of about 100 square micrometers.
The main function of alveolar cells is to secrete substances known as surfactants (SAAs), which play an important role in the process of respiration. The PA agent coats the inside of the alveoli, reducing their surface tension and allowing them to expand and contract as you inhale and exhale.
In addition, large alveolar cells are involved in protecting the lungs from infections and other harmful influences. They produce immunoglobulins and other proteins that help prevent pathogens from attacking lung tissue.
Despite the importance of alveolar large cells, their functioning can be impaired by various factors, including smoking, air pollution, infections and other diseases. This can lead to various lung diseases, including bronchitis, pneumonia, chronic obstructive pulmonary disease and others.
In conclusion, alveolar large cells are an important component of pulmonary function and play a critical role in maintaining the health of the respiratory system. Therefore, protecting and maintaining lung health should be a priority for every person.
