The Circulatory system is the system that helps your heart beat. The first Organ of the Circulatory system is the veins. The veins go straight to the heart. When you are at the heart, you go to the first chamber called the Right Atrium which does not have oxygenated blood yet. Then you go through the tricuspid valve, which keeps the blood in place to go to the right ventricle. The Right Ventricle still does not have oxygenated blood. Then you are tired of not having oxygenated blood you go through the pulmonary valve to the lungs and finally get oxygenated blood after that, you go to the left ventricle through the mitral valve, and finally at the left ventricle.
I like science because you learn new stuff in your body.
Thanks for reading my blog post about The Circulatory system.
Thank you for sharing what you are learning in Science. It is very fascinating to learn about the human body. Is Science one of your favourite subjects? Although fascinating, I always found science difficult in school. What do you think your next Science topic will be?
