The human body is made up of 60 trillion cells, each one a living, breathing entity that works together to keep us alive. Every cell has its own unique job, from absorbing oxygen to pumping blood throughout our veins. Our hearts beat around 3 billion times in a single lifetime, pumping over 1.5 million barrels of blood, enough to fill 200 train tank cars. The human brain contains over 70,000 miles of blood vessels, making it one of the most complex systems in the body.
