Question

What is the role of surfactant in respiration?

Answer 1

Surfactant is a substance (lipid) that reduces water's surface tension. This is important in the structure because the water atoms will not stay together. This means that the water will extend as a far membrane around the alveolus. Furthermost , it prevents the alveolus from imploding while exhaling.

Complete answer:
The granular cells of the pneumonic alveoli expel a greasy membrane made up of surfactant.
Pneumonic surfactant, a phospholipid and protein combination that reduces surface strain in the flimsy liquid covering inside all alveoli, makes re swelling of the alveoli after exhalation easier. The decrease in surface strain allows the layer to isolate, increasing its ability to trade gas. Surfactant's primary function is to reduce surface pressure at the air/fluid interface inside the lung's alveoli. This is expected to reduce the amount of carbon dioxide produced by breathing and to prevent alveolar breakdown at the end-of-life.
Surfactant is delivered by extraordinary alveolar cells (granular pneumocytes, a cuboidal epithelial), which are the most diverse cells in the alveoli but do not cover as much surface area as squamous alveolar cells.
Exocytosis is consistently used to deliver the surfactant. It encases a hidden aqueous protein with a hypo phase and an overlying phospholipid film composed primarily of dipalmitoyl phosphatidyl choline.

Note:
Aspiratory surfactant is a unique blend of lipids and surfactant-specific proteins that coats the alveolar surface of the lungs. Surfactant isn't only found in the alveolar compartment; it's also found in upper aviation route discharges and arrives at terminal guiding aviation routes. Although the function of surfactant in the alveolar compartment has been thoroughly explained in terms of both health and infection, the potential role of surfactant in aviation routes warrants further investigation.
