In this embryology lecture, Professor Zach Murphy explains the development of fetal circulation, focusing on how the cardiovascular system adapts to support the fetus before birth. The lecture follows the formation of critical vascular structures and fetal shunts that ensure proper oxygenation and nutrient delivery in utero. We begin by exploring the roles of the umbilical vein, umbilical arteries, and placenta in maintaining fetal gas exchange and metabolic balance. Zach explains how oxygenated blood from the placenta bypasses the liver via the ductus venosus, enters the right atrium, and is then diverted through the foramen ovale into the left atrium to prioritize perfusion of the brain and upper body. Next, the lecture highlights how blood from the right ventricle is directed away from the non-functioning fetal lungs through the ductus arteriosus, which connects the pulmonary artery to the descending aorta. You’ll also learn about the pressures, resistances, and flow patterns that are unique to fetal life and how they rapidly change after birth.
