The Human Heart

If you were to live to age 75, over the course of your life your heart would beat more than 2.5 billion times. A muscular organ, the human heart pumps blood throughout the body.

Some facts about the human heart:
  • It is the size of a fist.
  • The heart is like a double pump - the right side collects de-oxygenated blood, while the left side collects oxygentated blood.
  • The heart is divided into four main chambers.
  • The double membrane of the protective sac surrounding the heart is filled with pericardial fluid which nourishes the heart and prevents the heart from shocks.
This image of the human heart was captured with a biological microscope using a Jenoptik C14 microscope camera.
