An adult takes about 12 breaths per minute, inhaling roughly 500ml of air with each breath. the molar compositions of the inspired and expired gases are as follows: species inspired gas (%) expired gas (%) o2 20.6 15.1 co2 0.0 3.7 n2 77.4 75.0 h2o 2.0 6.2 the inspired gas is at 24°c and 1 atm, and the expired gas is at body temperature and pressure (37°c and 1 atm). nitrogen is not transported into or out of the blood in the lungs, so that n2in n2out. (a) calculate the masses of o2, co2, and h2o transferred from the pulmonary gases to the blood or vice versa (specify which) per minute. (b) calculate the volume of air exhaled per milliliter inhaled. (c) at what rate (g/min) is this individual losing weight by merely breathing? (d) the rate at which oxygen is transferred from the air in the lungs to the blood is roughly proportional to po2 air po2blood , where po2blood is a quantity related to the concentration of oxygen in the blood. compared to regions where atmospheric pressure is 14.7 psia, what effect 17 see problem 4.17 for definitions and source of data. safety bioengineering 250 chapter 5 single-phase systems does the atmospheric pressure in denver, which is approximately 12.1 psi, have on the transport rate and breathing rate? how does the body adjust to address this condition?
