Heart and circulation

The heart is among the first organs to go to work in life and when it stops beating this usually marks the end of life. In a lifetime, the heart beats countless times and pumps millions of liters of blood through the blood vessels. This circulatory system works relentlessly – and needs surprisingly little to be kept healthy.
