Individuals vary considerably in total lung volume. Figure P1.94 shows the results of measuring the total lung volume and average alveolar volume of six individuals. From these data, what can you infer about the relationship among alveolar size, total lung volume, and number of alveoli per individual? As the total volume of the lungs increases,

(a) The number and volume of individual alveoli increase;

(b) The number of alveoli increases and the volume of individual alveoli decreases;

(c) The volume of the individual alveoli remains constant and the number of alveoli increases;

(d) Both the number of alveoli and the volume of individual alveoli remain constant.
