Why does our heart beat?

When you run and then stop, you can feel your heart pumping.

We are lucky to have hearts because our hearts is the thing that keeps us going on and keeps us alive. Our heart is what keeps us from being able to move. If you eat too much, your heart might stop beating. Then your heart might stop beating because it might be lined too much fat and that stops stops the blood going through to make the heart beat. When you run fast, you need more oxygen and thats why your heart beats because your brain send a message to the heart for it to beat faster. Every heart beat is the sound of the heart pumping to push the blood around the body.

The heart pumps oxygen-rich blood through tiny tubes that circulates  to every part of the body. The system is called the circulatory system. Blood has four main componenstred blood cells, white blood cells, liquid and plasma.

After blood is pushed to all parts of the body, it is then pushed back again. (It takes less than a minute for blood to go  around the  body.)

Blood runs through the veins and into the heart to make it pump. If you cut your veins by accident on accident and the blood stops flowing to your heart then your heart will stop pumping. If you remove your heart,you will die. Also if you hold your breath for to long then you might die of faint. If you are in a deep pool and you drown, you will die because of the lack of oxygen to the heart.

Our hearts are important because if you don’t have one then you will not be alive. Our hearts keeps us moving and doing amazing things. The heart is like on the left side of the chest.  if you eat to much sugar. But if you eat too much sugar or salt by itself, you might die.

Our hearts are important because it is what keeps us alive and so we need to look after it.
