Question

During the breathing cycle lungs always contain a residual volume of air.why ?

Answer 1

The lungs always contain a residual volume of air so that during breathing cycle there is sufficient time for oxygen to be absorbed and for the carbon dioxide to be released. Residual Volumeis important because it prevents the lungs from collapsing.

HOPE THIS HELPS YOU

Answer 2

Answer:

The lungs always contain  residual amounts of air, so  there is ample time for oxygen uptake and  carbon dioxide release during the breathing cycle.

Explanation:

Residual air volume is the amount of gas that remains in the lungs at the end of maximum exhalation. Residual air volume is important to prevent the lungs from collapsing.

The lungs always contain  residual amounts of air, so  there is ample time for oxygen uptake and  carbon dioxide release during the breathing cycle. In addition, due to the presence of residues, there is ample time for oxygen uptake and  carbon dioxide release during breathing.
