Current Research, Models and Findings
Physiological factors in fetal lung growth
This article looks at the current findings of different physiological factors that affect normal neonatal, functioning lungs upon during fetal development. The size of the paired organ to be able to exchange carbon dioxide with oxygen for the very first time at birth, is crucial to be able to withstand that pressure. As we know surfactant, is a lipid-protein composite. It is crucial to the function of the neonatal lung because:
A. Its high viscosity and low surface tension stabilize the diameter of the alveoli and prevent their collapse after each expiration.
B. Because the alveoli remain partially open, they are expanded on inspiration with much less expenditure of energy. [ANAT 2241 LEC 11-Respriation]
However, current research suggests that the production of surfactant which is reliant on hormonal factors, have little influence on fetal lung growth. In contrast, the following physiological lung growth factors were found to permit the lungs to express their inherent growth potential.
