William Harvey- Circulation of Blood
This storyboard does not have a description.
I studied the hearts not only of various fishes, amphibian, reptiles, birds, and mammals, but also those of various other animal species.
My observations of dissected hearts showed that the valves in the heart allowed blood to flow in only one direction. I measured the volume of the left ventricle and calculated that the amount of blood that passes through the heart of a man in an half hour and established that it was greater than the amount contained in the whole body.
I could go on and on. Of course I get into more detail in the book I just published "De Motu cordis".
Well thank you for that. and thank you viewers for watch You Are There!!!
