Giraffe bending to drink. In a giraffe with its head 2.14 m above its heart, and its heart 2.20 m above its feet. thelhydrostatic} gauge pressure in the blood at its heart is 273 torr. Assume that the giraffe stands upright and the blood density is 1.06 K 103 kgfms. In torr (or mm Hg}. nd the {gauge} blood pressure [a] at the brain [the pressure is enough to perfuse the brain with blood, to keep the giraffe from fainting} and {b} at the feet [the pressure must be countered by tighttting skin acting like a pressure stocking}. [c] If the giraffe were to lower its head to drink from a pond without splaying its legs and moving slowly. what would be the increase in the blood pressure in the brain? (Such action would probably be lethal.}
