Understanding how the heart works

Your heart is an amazing powerhouse that pumps and circulates 5 or 6 gallons of blood each minute through your entire body

Understanding how the heart works

To understand heart disease, you must first know how the heart works. The heart is like any other muscle, requiring blood to supply oxygen and nutrients for it to function. It beats about 100,000 times a day, pumping blood through your circulatory system. The cycle of pumping blood throughout your body carries fresh oxygen to your lungs and nutrients to your body's tissues. Blood also takes waste, such as carbon dioxide, away from your tissues,. Without this process, we could not live.
