Today I'll take you through a day in my life. Get ready for a ride!
Hi! I'm Bertie the blood cell! I travel through your body to deliver blood!
I'll take you through each place and explain what I am doing!
First I enter the heart through the Superior Vena Cava which leads to the Right Atrium. From there I go to the Right Ventricle up into the Pulmonary Valve and out of the Pulmonary Artery. Here, I am only OXYGEN POOR.
We then go get oxygen from the lungs which makes us OXYGEN RICH
We enter back into the heart from the Pulmonary Veins. We the enter the Left Atrium which leads to the Left Ventricle. Finally, we leave through the Aorta
Once we get back through the heart, we have to deliver oxygen to the foot.
Me!
Then we go back up to the heart.
Once I get back to the heart, I don't have any oxygen which means... AGAIN!!!
