Initiation of the Switch Over with Gaseous Hormone
Prostaglandin E
- In neonates, the ductus arteriosus and foramen ovale allow blood to bypass the lungs since they are not yet functional.
- The closure of these pathways is crucial for the establishment of the adult pattern of blood circulation.
- Prostaglandin E is a gaseous hormone that plays a key role in this process.
- It helps maintain the patency of the ductus arteriosus and foramen ovale in neonates by inhibiting their closure.
Role in Closure of Ductus Arteriosus and Foramen Ovale
- As prostaglandin E levels decrease, the ductus arteriosus and foramen ovale begin to constrict.
- This constriction is essential to redirect the blood flow through the heart, aorta, and pulmonary artery, allowing for proper oxygenation of the blood.
- The closure of these pathways is a critical step in the transition from fetal to adult circulation.
Establishment of Adult Pattern of Blood Flow
- Once the ductus arteriosus and foramen ovale have closed, the adult pattern of blood flow through the heart is established.
- Oxygen-rich blood is pumped from the left ventricle through the aorta to the rest of the body, while deoxygenated blood is sent to the lungs through the pulmonary artery for oxygenation.
- This switch over is a coordinated process that ensures the proper distribution of oxygenated blood throughout the body.
Conclusion
- In neonates, the switch over from fetal to adult circulation is initiated by the decrease in prostaglandin E levels, leading to the closure of the ductus arteriosus and foramen ovale.
- This transition is essential for the establishment of the adult pattern of blood flow through the heart, aorta, and pulmonary artery, ensuring proper oxygenation of the blood.
