Jlenok [28]3 years ago

Explanation:

  • One of the main differences between adult and fetal circulation is <em>the direction and where the non-oxygenated and oxygenated blood circulates</em>. In adults arteries carry oxygenated blood away from the heart and veins carry non-oxygenated blood towards the heart; in fetuses, arteries carry non-oxygenated blood away from the heart and veins carry oxygenated blood back to the heart.
  • Another difference is <em>where does the exchange of gases takes place</em>, in fetuses blood is oxygenated in the placenta, in adults in the lungs.
  • The circulation between adults and fetuses differs in <em>where does the pressure increases</em>, in adults is on the left side of the heart, in fetuses on the right side.
  • Finally,<em> another important difference between adults and fetuses is the presence of shunts</em>, in fetuses these shunts allow both sides of the heart to work parallelly letting mix blood from both ventricles. This shunt gets closed after birth, so adults do not have them.

I hope you find this information useful! Good luck!

Why<br>is the hepatic portal<br>portal vein<br>unique ?​
LiRa [457]

Answer:

Blood flow to the liver is unique in that it receives both oxygenated and (partially) deoxygenated blood. As a result, the partial gas pressure of oxygen (pO2) and perfusion pressure of portal blood are lower than in other organs of the body.
