Why does our hearts beat?
Your heart is divided into four separate parts . The top two are called atria and the bottom two are called vertical.There are valves and they stop the blood from going back the way it came They act in one system.
Our heart keeps us alive. Our heart gives us oxygen so we can inhale and exhale to breath. heart beats really fast when we run or jog because we need more oxygen in our blood, so the heart pumps faster to provide. If your heart stops beating you will die.
Every heart beat sounds like drum banging to push the blood around the body. The heart pumps oxygen through tiny tubes that goes to every part of the body. When you're running fast your body needs more oxygen so your heart beats faster to pump more blood. After blood is pushed back again it takes less than a minute to go around the body.
When you breath fast your heart pumps fast and when you breath slowly your heart pumps slow. When you feel the side of your neck, you can feel your heart pumping because The veins are connected. When you stop breathing your heart stops pumping and you die. Blood has to every part of your body four main parts: red blood cells, white blood cells, liquid and plasma.
