The functions of the respiratory system include all of the following except
providing to the bloodstream and removing .
creating air pressure that allows for swallowing.
enabling vocalization as expired air passes over the vocal cords.
assisting in abdominal compression.

the nasal cavity.
the pharynx.
the trachea.

The Bronchial tree is connected with the brain by
Trigeminal nerve
Phrenic nerve
Vagus nerve
Trochlear nerve
Hering Breur Reflex serves as a protective mechanism to prevent
Excess lung inflation
Excess oxygenation
All these
Tracheal collapsing
The chief difference between Trachea and Bronchioles is
Trachea lacks cartilage
Bronchiole lacks cartilage
Trachea is long
Bronchiole is small
At high altitude, the number of RBC increases
To trap from rarefied air having low
To adapt with the oxygen deficiency
To remove more
To increase metabolism
Bohr effect shifts the – Hb dissociation curve to right
To promote oxygenation of Hb in lungs
To increase concentration
To decrease concentration
To decrease the pH of blood
Spirometry is used
To detect the amount of Hemoglobin
To detect the air flow through the respiratory system
To check the respiratory quotient
None of these
Pulmonary ventilation is
