Hearts Coloring Pages, Free Printable Hearts Coloring Pages for Kids, The heart continuously supplies organs and tissue with blood – and thus with vital oxygen and nutrients. One can imagine the heart as a central pump that drives the blood circulation. In adults, the heart beats about 60 to 80 times per minute at rest; at every heartbeat, it pumps blood through the body. If you exert yourself physically, the heart beats faster. As a result, the blood also flows faster through the body. It can then absorb more oxygen per minute in the lungs and supply the body cells with more oxygen.
