watch the following video to learn more about lung volumes and spirometers.
spirometry

spirometry is used to measure all of the following except:
expiratory reserve volume
tidal volume
inspiratory capacity
total lung capacity

question 22

the compound formed when carbon dioxide combines with hemoglobin is
carbamino compound.
oxyhemoglobin.
carbaminohemoglobin.
bicarbonate ion.

Explanation:

Question 21

Spirometry measures volumes like Expiratory Reserve Volume, Tidal volume, and Inspiratory capacity. Total lung capacity includes residual volume (not measured by spirometry as it requires other methods like helium dilution).

When carbon dioxide combines with hemoglobin, it forms carbaminohemoglobin. Carbamino compound is too general. Oxyhemoglobin is when oxygen binds to hemoglobin. Bicarbonate ion is formed when carbon dioxide reacts with water (not directly with hemoglobin in this context).

Answer:

Total lung capacity
