Question

The total inside capacity of lungs is _____ for man.

Options
  • A

    6.7 litres

  • B

    2.5 litres

  • C

    7 litres

  • D

    5-6 litres

Explanation

In an adult human being when the lungs are fully inflated the total inside capacity of lungs is about 5-6 litres.

This figure is too high for the average total lung capacity of an adult male. 5-6 liters is the average total lung capacity for an adult male, encompassing all lung volumes when the lungs are fully inflated.

This value is too low to represent the total lung capacity, which includes all lung volumes. 5-6 liters is the average total lung capacity for an adult male, encompassing all lung volumes when the lungs are fully inflated.

While some individuals might have a lung capacity close to this, it exceeds the average capacity for most adult males. 5-6 liters is the average total lung capacity for an adult male, encompassing all lung volumes when the lungs are fully inflated.

This is the average total lung capacity for an adult male, encompassing all lung volumes when the lungs are fully inflated.
