Pulmonary surfactant, secreted via exocytosis of lamellar bodies (LB) by alveolar type II (AT II) cells, maintains low alveolar surface tension and is therefore essential for normal lung function.
This in turn causes abnormalities in the levels of the other hormones, Estrogen and Progesterone, thus adding to the chemical turmoil in the body.
