Which of the following best describes tidal volume? options:
1.The amount of oxygen in the air at sea level.
2.The maximum volume of air that can be moved in and out of the lungs with forced breathing.
3.The volume of air moved in and out of the lungs with each breath while at rest.
4.The amount of oxygen picked up by the blood with every breath.
ANSWER
Option 3 is correct. (I.e, The volume of air moved in and out of the lungs with each breathe while at rest.)
EXPLANATION - Tidal volume in the respiratory system is defined as the volume of air that is drawn in or expelled out during a single normal (quiet) breathing act without any extra effort. In a normal healthy adult human being, the average value of tidal volume is about 500ml.
The other options are invalid as they don't correctly describe the tidal volume.
