The Greatest of Allah

In normal post-natal circulation, vein always bring deoxygenated blood except for pulmonary vein that carry oxygenated blood from the lungs to the heart. For oxygenated blood, it always been carried by artery except for pulmonary artery that carry deoxygenated blood to the lungs for the gaseous exchange.

But, in fetal circulation, the pathway is vice versa. Fetal is connected to the mother through the placenta. And the umbilical cord has the job to connect the placenta with the fetal. Qxygenated blood from the placenta is transferred to the fetal via umbilical vein, while the deoxygenated blood and waste product from the fetal is transferred to the placenta via umbilical artery. 

Subhanallah, it is the greatest of Allah for the creation of human kind. Why Allah make the circulation of the fetal is vice versa with post-natal circulation?

It is because, if oxygenated blood is transferred to the fetal through umbilical artery, the fetal will burst and damage due to the high pressure. Artery has more pressure than vein because they have to pump the deoxygenated blood to all part of the body.


Nota Hati:

1. Iqra'. Bacalah dengan nama tuhanmu.

2. Aplikasikan apa saja ilmu yang dapat, dan kaitkan dengan kebesaran Allah. Anda akan tersenyum dan rasa dekat dengan Allah.
