Your blood pressure (typically reported as "120 over 70" or something like that) has two parts: the first number is the systolic pressure, which is the arterial pressure during the contraction of the heart, and the second number is the diastolic pressure, which is the arterial pressure when the heart is relaxed a. blood pressures are typically given in torr, or millimeters of mercury (1 torr 1 mmhg). using the fact that mercury has a density of 13.6 g/cm3, derive a conversion factor between torr and pascals, and use it to convert 80 torr into pa these blood pressures are known as gauge pressures, meaning that they are the amount by which the blood pressure exceeds atmospheric pressure. the first measurement of blood pressure involved inserting a long cannula (needle-tipped tube) into the artery of a horse. the other end of the tube was left open to the atmosphere. if the horse's systolic blood pressure were 140 mmhg, how high would the blood from that artery have risen in the cannula? assume that blood has the same density as water as we'll see when we study fluid dynamics, fluids flow from high pressure to low pressure. using your results from parts a) and b), why must iv bags be placed at least 20 cm above a patient's arm? b. c.

Imagine a planet that has a similar atmospheric pressure to earth (760 mmhg) but different concentrations of gases in its atmosphere. on this hypothetical planet, oxygen makes up 10% of the atmosphere, carbon dioxide makes up 15%, and nitrogen makes up the remaining 75%. based on this information, what is the partial pressure of oxygen on this new planet? 646 mmhg 114 mmhg 160 mmhg 76 mmhg 571 mmhg
