1. Cardiorespiratory Adjustments at Birth
1) during fetal life
: the placenta and not the lungs serves as the organ for gas exchange. the normal fetal circulatory pattern is arranged very differently from that observed after birth.
The placental circulation is in a parallel arrangement
receives blood from the descending aorta
drains blood to the systemic venous circulation.
The fetal circulation : a series of intra- and extracardiac shunts that allows the oxygenated blood to flow from the placenta to the systemic organs and for the deoxygenated blood to return to the placenta..
Lungs are not required for gas exchange; pulmonary blood flow is low (approximately 10% of the combined ventricular output), yet adequate for lung growth and development.
the blood exiting the lungs has a lower saturation than does blood entering the pulmonary circulation, they are metabolically active, secreting liquid into the potential air spaces and synthesizing surfactant, a substance that is vital to achieve adequate ventilation at birth. The fetal lungs are also physically active in that they simulate breathing movements.
