The Journey of the Heart
I am a drop of blood coming from the brain. I am the deo-oxygenated blood, but why me? Why me? I am the SUPERIOR VENA CAVA I am going to be pumped by the heart into the lungs to be cleaned. My journey begins now!!
I knock on the right atrium please let me in I need to be cleaned the right atrium opens the door and I pass through a tiny opening called the tri-cusped valve then I go down into the right ventricle and I see the septum. The septum divides the heart into two. Then we went in the pulmonary artery (is the only artery that carries deo-oxygenated blood)it took us to the lungs these are organs in our body. They are responsible about inhaling oxygenated blood and exhaling deo-oxygenated blood. They are like a balloon, when we inhale they are inflated. The lungs started washing us. From the lungs we went back to the left atrium, by the pulmonary vein it’s the only vein that carries deo-oxygenated blood. The mitral valve opens and we go down to the left ventrical after that we are pumped to the aorta the aorta takes us to all body parts.
This is how my blood circulates in my body over and over again.
