The heart is the most important muscle in your body that is constantly pumping blood around our body through blood vessels. Your heart is in your chest and is well protected by your rib cage. The heart is made out of four chambers: the left atrium, right atrium, left ventricle and right ventricle. Those four parts of your heart make sure blood only goes one way, either in or out. Blood that leaves the heart is carried through arteries. The main artery leaving the left ventricle is the aorta while the main artery leaving the right ventricle is the pulmonary artery.
There are seventy-eighty organs in our body. Did you know? The skin is a organ too! These are the ones we’re going to talk about. Liver, kidneys and lungs. Your liver is right under your abdomen, under your rib cage and it’s very important for your health. The liver is the largest solid organ in your body. When your fully grown, it can grown to the size of a football! The liver has many jobs, but here is a main one: it cleans your blood. The kidneys are beans- shaped organs, each about the size of your fist. They are near the middle of your back just below the rib cage. Did you know? You need at least one kidney to live! Each day with our lungs we breath about 20,000 times! When you breathe air, your lungs fill and then empty out. If you never had lungs you would never be alive!
