Heart and Blood Vessels

Every minute of your life, the heart relaxes approximately 70 times while pumping 5 liters of blood. If necessary, it can multiply this blood volume to an incredible 25 liters of blood per minute. The heart of a 70-year-old individual can have more than 2.5 billion contractions, which has pumped over 220 million liters of blood. So you can imagine how important it is to keep your heart and blood vessels in shape.
