The circulatory system

We started the year in Biology class with learning about the circulatory system. We started by watching a video by Bozeman Science and learning new vocabularies. Your heart has four chambers. There is no start to the circulatory system because it is circular, meaning it repeats the procedures over and over again until you eventually die. How the circulatory works are the deoxygenated blood that comes from your body through the veins enter the Right Atrium(RA) of your heart. Then it goes through a valve and enters the Right Ventricle(RV). The RV pumps the deoxygenated blood to the lungs to get rid out of carbon dioxide and get oxygen. The oxygenated blood comes back to the Left Atrium(LA) and it filters through a valve to the Left Ventricle(LV). The LV pumps the oxygenated blood to your whole body.
