Lung

The lungs are the primary organs of the respiratory system in many animals, including humans. In mammals and most other tetrapods, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the atmosphere and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange. Respiration is driven by different muscular systems in different species. Mammals, reptiles and birds use their musculoskeletal systems to support and foster breathing. In early

Beractant, also known by the trade name of Survanta, is a modified bovine pulmonary surfactant containing bovine lung extract (phospholipids, neutral lipids, fatty acids, and bovine surfactant proteins), to which synthetic DPPC, tripalmitin and palmitic acid are added. The composition provides 25&nbsp;mg/mL phospholipids, 0.5 to 1.75&nbsp;mg/mL triglycerides, 1.4 to 3.5&nbsp;mg/mL free fatty acids, and <1.0&nbsp;mg/mL total surfactant proteins. As an intratracheal suspension, it can be used for the prevention and treatment of neonatal respiratory distress syndrome. Survanta is manufactured by

thumb|WI-38 cells (Left: in high density. Right: in low density) WI-38 is a diploid human cell line composed of fibroblasts derived from lung tissue of a 3-month-gestation female fetus. The fetus came from a legal abortion performed in Sweden in 1962. The cell line was isolated by Leonard Hayflick the same year, and has been used extensively in scientific research, with applications ranging from developing important theories in molecular biology and aging to the production of most human virus vaccines. The uses of this cell line in human virus vaccine production is estimated to have saved the
