Blood pressure in Argentinosaurus. If this long-necked, gigantic sauropod had a head height of 20.2 m and a heart height of 9.00 m,
(a) what (hydrostatic) gauge pressure in its blood was required at the heart such that the blood pressure at the brain was 62.5 torr (just enough to perfuse the brain with blood)? Assume the blood had a density of 1.06 × 103 kg/m3.
(b) What was the blood pressure at the feet? Give your answers in torr or mm Hg.
