Did you know?
Because I love learning the most random/interesting things, let's all share something that others may not know.
That the fetal circulatory system has 3 spots where they bypass major organs. The liver, then two meant to bypass the lungs (one in the was separating the left and right atrium and another in the pulmonary artery)
The babies send a small amount of blood to maintain the organs but it saves energy because the baby is getting oxygen and filtered blood from mom. :)
You can't lick your elbow...I actually know a girl who can, but most people can't. She must be double jointed lol
