Question

Differentiate between

a. Vital capacity and Tidal volume
b. Emphysema and Bronchitis

Open in App

Solution

Criteria Vital capacity Tidal volume

Definition The maximum volume of air that can be inspired by a person after a forced expiration or expired after a forced inspiration.
It is the volume of air we breathe in and out during normal breathing.

Criteria Emphysema Bronchitis

Definition Lung condition that gets developed by cigarette smoking and inhalation of toxic gases Lung disorder that gets developed due to the tar, carbon monoxide, etc., in tobacco

Effects Alveolar walls are damaged and there is decrease in the respiratory surface Leads to the deposition of mucus and the swelling of lungs due to the proliferation of germs in the alveoli.

Differentiate between

(a) Inspiratory and expiratory reserve volume

(b) Vital capacity and total lung capacity.

From the following relationships between respiratory volume and capacities, mark the correct option.

(i) Inspiratory Capacity (IC) = Tidal Volume + Residual Volume

(ii) Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV).

(iii) Residual Volume (RV) = Vital Capacity (VC) - Inspiratory Reserve Volume (IRV)

(iv) Tidal Volume (TV) = Inspiratory Capacity (IC) - Inspiratory Reserve Volume (IRV)
