When a person who cannot breathe properly is placed on a ventilator, an air mixture is delivered at pressures that are alternately above the air pressure in the person's lung, and then below. How will this move oxygen gas into the lungs, and carbon dioxide out? Complete the sentences below. Choices are below.

a. More gases will pass (blank) the blood when higher gas pressure is introduced by a ventilator.

b. More gases will pass (blank) the blood when a lower gas pressure is introduced into the lungs.

c. Because the air mixture has a (blank) partial pressure of oxygen than the blood, oxygen would (blank).

d. Because the air mixture has a (blank) partial pressure of carbon dioxide than the blood, CO2 would (blank).

Choices for #2:

enter the bloodstream

out of

be expelled

into

higher

lower

When air (21 mol% O2, 79 mol% N2) is placed in contact with 1000 cm3 of liquid water at body temperature, 37°C, and 1 atm absolute, approximately 14.1 standard cubic centimeters [cm3(STP)] of gas are absorbed in the water at equilibrium. Subsequent analysis of the liquid reveals that 33.4 mol% of the dissolved gas is oxygen and the balance is oxygen a) Estimate the Henry’s law coefficients (atm/mole fraction) of oxygen and nitrogen at 37°C b) An adult absorbs approximately...

Typically, when a person coughs, he or she first inhales about 2.10 L of air at 1.00 atm and 25 ∘C. The epiglottis and the vocal cords then shut, trapping the air in the lungs, where it is warmed to 37 ∘C and compressed to a volume of about 1.70 L by the action of the diaphragm and chest muscles. The sudden opening of the epiglottis and vocal cords releases this air explosively. Just prior to this release, what is...
