 My Blood Journey Well, I know about it, it’s called a circulatory/transport system. First, deoxygenated blood travels through two veins called inferior vena cava and superior vena cava. The inferior vena cave transports blood from the lower part of the body. The superior vena cava transports blood from the upper part of the body. The deoxygenated blood then goes to the right atrium. When the deoxygenated blood gathers together in the right atrium, a valve called tricuspid valve opens permitting blood to flow to the right ventricle. Then it pumps this blood to an artery called pulmonary artery. This artery is the only artery that carries deoxygenated blood. It transports the blood to the lungs in order to get rid of carbon dioxide (co2). When we exhale it. Oxygen enters the heart when we inhale. From the lungs oxygenated blood is carried by a vein called pulmonary vein. It is the only vein that carries oxygenated blood. It transports the blood to the left atrium. When the oxygenated blood gathers together and another valve called mitral valve opens permitting the blood to the left ventricle. The mitral valve is always on the left side of the heart. The tricuspid valve is always on the right side of the heart. And then the aorta the biggest and longest artery carries the oxygenated blood to the rest of the body parts, to feed our cells who are waiting to be fed. This cycle goes on and on in a fast motion.
