 My Blood Journey My Blood Journey Have you ever wondered how your heart functions? The heart is a part of a system called Transport/Circulatory System. My story starts when the deoxygenated blood comes from the superior vena cava (the upper part of our body), and the inferior vena cava (the lower part of our body), from there my blood goes to the right atrium and gets stuck and squished until there is lots of blood, when there is lots of blood the tricuspid valve opens, and lets my blood pass through the tricuspid valve, to the right ventricle, and gets taken away by the pulmonary artery that carries deoxygenated blood to the lungs, to get rid of the gas waste, carbon dioxide. Then I inhale oxygen, and happily the pulmonary vein that carriesoxygenated blood takes the oxygenated blood to the left atrium, and gets stuck and squished again waiting for more blood to transport to the left atrium, when there is lots of blood the mitral valve opens, and the blood flows to the left ventricle, and gets taken away by the aorta to the body cells who are waiting for me to be fed. And that’s how our heart functions. My advice to you is that to exercise a lot, avoid polluted areas, avoid smoking people, and eat healthy food to help your transport system function.
