The partial pressure gradient for oxygen in the body is much steeper than that for carbon dioxide. Explain how equal amounts of these two gases can be exchanged (in a given time interval) in the lungs and at the tissues. What law describes this
phenomenon?
What will be an ideal response?
Equal amounts of oxygen and carbon dioxide can be exchanged in the lungs and at the tissues because carbon dioxide is 20 times more soluble in water than oxygen. Henry's law states that the degree to which a gas dissolves in a liquid is proportional to both its partial pressure and its solubility in the liquid.
