Clearly explain the difference between external and internal respiration.

Gas exchange at the blood air barrier is efficient because (a) the differences in partial pressure are substantial, (b) the gases are lipid soluble, (c) the total surface area is large, (d) of all of these.

Oxygen and carbon dioxide are exchanged in the lungs and through all cell membranes bya. active transport,b. diffusion,c. filtration,d. osmosis.

Doris has an obstruction of her right primary bronchus. As a result, how would the oxygen–hemoglobin saturation curve for her right lung compare with that for her left?

What is it about the structure of the alveoli that makes them an ideal site for gas exchange?

Why do individuals who are anemic generally not exhibit an increase in respiratory rate or tidal volume, even though their blood is not carrying enough oxygen?

What happens to the process of respiration when a person is sneezing or coughing?

Which of the following is NOT involved in respiration?
