ESV-If radius doubled, the blood flow increase by a factor of 16-If the length of the tube doubles the blood flow is decrease by a factor of 2-If the viscosity increases the blood flow will decrease-Gas exchange: unlike animals that are precise small, air diffuses f rom outside to the inside, however, for us (! humans) this is imposible because of our large size. So to pull in the oxygen to the tissue, we increase surface area to... If you call for to get a full essay, order it on our website: OrderEssay.net
