- At birthAt birth, the neonatal circulation transitions; systemic vascular resistance (SVR) increases and pulmonary vascular resistance (PVR) decreases; fetal shunts close, and blood flow to the neonatal lungs increases. Persistent fetal circulation results in neonatal hypoxemia and respiratory distress.

See more on teachmephysiology.comThe adult heart consists of 4 chambers, each with inflow and outflow. Its objective is to take deoxygenated blood from the body, transport it to the lungs for oxygenation, and then take this oxygenatedblood to the tissues. For more information on this, you can look at the physiology and anatomyof the heart. A fet…- 4.7/5
