Fetal Circulation - Embryology

Explore the intricacies of fetal circulation in this comprehensive 46-minute embryology lecture. Delve into the normal fetal circulatory system, examining the path of oxygenated blood from the umbilical veins through various organs and vessels. Understand the multiple mixing points of oxygenated and deoxygenated blood, and learn about crucial structures like the ductus venosus, foramen ovale, and ductus arteriosus. Discover the significant changes that occur in fetal circulation after birth, including lung expansion and the reversal of blood flow in certain vessels. Investigate the mechanisms behind the closure of fetal circulatory components and their remnants in the adult body. Gain insights into clinical correlations, such as patent ductus arteriosus, and its treatment. This in-depth exploration provides a solid foundation for understanding the complexities of fetal and postnatal circulatory systems.
