Your "ticker" is about the size of your clenched fist. It’s not as big as you may think, but it does a mighty job. It is like a twin pump and is divided into two sides.

They are quite extraordinary. They are stable, adapt well and are tough but their efficiency is completely dependent on a good supply of oxygen and nutrient rich blood.

If oxygen is cut off they will stop in a minute or two.

The blood comes into the right side from the main veins in your body and pumps the blood into your lungs.

Human Heart

The left side then takes the oxygen rich blood from your lungs and pumps it out through your arteries to all parts of your body, day and night.
