Answer:
Spirometry is one of the most common tests used to diagnose diseases and disorders of the respiratory system.
Explanation:
Spirometry is a diagnostic method that allows us to determine the respiratory flow and volume that reflect normal lung function, as well as its possible alterations.
Using a spirometer, data on simple respiratory function is obtained, such as total lung capacity, vital capacity, inspiratory and expiratory tidal volume, as well as their equivalents in forced spirometry.
Spirometry is used for the diagnosis of respiratory diseases as well as for the routine evaluation of patients with chronic lung disease.
<em> With regard to the other options, since spirometry is limited to the study of lung function, it does not apply to the study of lymphatic, cardiovascular or circulatory systems.</em>
It is referred as <span>zone of proximal development. The zone of proximal development enables a person to distinguish what he or she is capable of with help towards others and without it.
