Your heart is a vital organ. It is a muscle that pumps blood to all parts of your body. The blood pumped by your heart provides your body with the oxygen and nutrients it needs to function.
Your heart is about the size of a clenched fist, and weighs between 300 and 450 g. It lies in the middle of your chest, behind and slightly to the left of your breastbone.
If you are of average body weight and size, your body contains about five litres of blood, all of which passes through your heart every minute or so. When necessary, such as during exercise, your heart can pump up to four times that amount per minute.
