Question

A fetus has a connection between the right and left of its heart. This allows blood to bypass the lungs. Explain why this bypass is necessary

Answer 1

Explanation:

Before birth, the foramen ovale allows blood flow to bypass the lungs (a fetus gets the oxygen it needs from the placenta, not the lungs). That way, the heart doesn't work hard to pump blood where it isn't needed. When newborns take their first breath, a new flow direction happens.

Explanation:

The purpose of these shunts is to bypass the lungs and liver. That's because these organs will not work fully until after birth. The shunt that bypasses the lungs is called the foramen ovale. This shunt moves blood from the right atrium of the heart to the left atrium.
