Hello Ms. Muna and fellow students. Today in Biology class I criticized the presence of a heart in the human circulatory system. I made this video to show how perpetual motion (never-ending motion that doesnt need more energy to continue) can be applied to blood, making the energy-consuming heart organ useless. Hope you enjoy. I would like to receive criticism on my argument, but please not about the video itself. I just made it in half an hour, so it is bound to have some mistakes (like typos, for instance). __________________________
