Inspiratory Reserve Volume
This question doesnt make sense
respiratory system
The residual volume is the portion of air in the respiratory tract that cannot be exhaled.
The amount of air that is inhaled or exhaled in one breath during unforced breathing is the tidal volume.
Respiratory volume is defined as how much air a person can hold in their lungs. Respiratory volume can be measured by having the person take a deep breath, and blow out into a device that measures air capacity.
Dead space volume
tidal volume
The larges component of air - is Nitrogen (approximately 79 % by volume).
Vital Capacity is the largest volume of air that can be breathed in and out in one breath.
The ERV is the expiratory reserve volume, which is the amount of air that can be forcefully exhaled after a normal tidal volume exhalation.
I think you mean the diaphragm, and that's part of the respiratory system. It's a muscle below the lungs, and when it tightens, it increases the volume of the cavity the lungs are in, so the lungs increase in volume as well, and air rushes into the lungs.
Due to the presence of dead space
Dead space volume is when some of the inspired air fills the conducting respiratory passageways and never contributes to gas exchange in the alveoli.
