Summary- The reason why our hearts beat is because we have an energy input output that makes the muscles in our heart move to pump oxygen through our bodies. With out a heart we would be either dead or some sort of creature that scientists made. If a human has a infection in there heart they will go through having a heart replacement. Why do we need a heart, simply because all life needs oxygen to survive. Most people think our lungs process oxygen to the brain but blood is what contains the oxygen through the jugular vein.
Critique- I think that we could increase oxygen by putting a oxygen amplifier or filter for maximum intake. I have a friend that told me his uncle had a heart replacement and I thought why not make a filter to reduce infections in hearts, and amplifiers to increase oxygen intake for runners for the Olympics and everyday sports. Future devices maybe?
Impact- Hearts can kill yourself if you don’t take care of them correctly. Are hearts a burden on humans because they are so fragile?
