Do you think the person with the greatest vital capacity can hold their breath longer than those with a lower vital

capacity? Consider the difference between internal respiration and external respiration and explain why lung capacity

may not have a great effect on the length of time you can hold your breath.

Since only external respiration occurs in the lungs, lung capacity may not have a great effect on the length of time you can hold your breath.

What is vital capacity?

Vital capacity is the maximum amount of air a person can inhale after a maximum exhalation.

Difference between internal respiration and external respiration

External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air.

Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.

Thus, since only external respiration occurs in the lungs, lung capacity may not have a great effect on the length of time you can hold your breath.
