The average person takes 500mL of air into the lungs with each normal inhalation, which corresponds to aproximately 1x10^22 molecules of air. Calculate the number of molecules of air inhaled by a person with a respiratoy problem who takes in only 350mL of air with each breath. Assume constant pressure and temperature.

Name 13. During gas exchange in the lungs, several factors affect the rate of gas diffusion across alveolar (the alveoli are tiny air sacs in the lungs) and tissue membranes. One of the factors is the difference in partial pressures of the gases across the membranes. The gases will diffuse from an area of high partial pressure to an area of low partial pressure, Look at the illustration below and note which blood vessels carry blood away from the lungs...
