I really need to learn about the path that a red blood cell takes around the body!!
'Ello madam. I couldn't help but notice that you were struggling. Mind having a yee bit of help from a jolly street rat?
Fantastic! Let's go to my lab....
Sure! I'm desperate!
Yes. Nowadays rats own their own homes and labs. Get used to it. Now what do you need to learn, lad?
Woah! You actually have a lab!!!
I need to know about oxygen rich and oxygen low blood. I also need to know about the lungs, chambers of the heart, the purpose of the circulatory system, and the type of blood vessels traveled in!!
Well, there are 4 chambers of the heart, the right atrium, right ventricle, left atrium, and the right ventricle. The purpose of the circulatory system is to transport products from the digestive system and respiratory system to the cells! The type of blood vessels traveled in are the arteries, veins, and capillaries.
