Question

What is the typical residual volume (in milliliters) for a healthy, 70 kg male?

a) 1200 mL
b) 2300 mL
c) 3000 mL
d) 5000 mL

Answer 1

The typical residual volume for a healthy, 70 kg male is about 1200 mL, which is important in maintaining the structure of the alveoli after exhalation.

Step-by-step explanation:

The typical residual volume for a healthy, 70 kg male is approximately 1200 mL. Residual volume is the amount of air left in the lungs after a forced exhalation, and it is important for preventing the alveoli from collapsing. This information is generally taught during high school biology classes when students are learning about the human respiratory system. To provide context, the total lung capacity of an adult male is about six liters, of which the residual volume is a part. Other components of the lung volumes and capacities include tidal volume (air inhaled in a normal breath), inspiratory reserve volume (additional air that can be inhaled after a normal inhalation), and expiratory reserve volume (additional air that can be exhaled after a normal exhalation).
