Respiration Process: Breathing and Gaseous Exchange and Respiratory Volume

What is vital capacity of our lungs ?

Functional residue capacity allows the small air passages to remain open and prevents the complete emptying of the lungs

An adult mammal with $50 \mathrm{kg}$ body weight has the following functional parameters of its lungs. Inspiratory reserve volume $=40 \mathrm{ml}/\mathrm{kg}$ body weight; Expiratory reserve volume $=15 \mathrm{ml}/\mathrm{kg}$ body weight; Vital capacity $=60 \mathrm{ml}/\mathrm{kg}$ body weight; Breathing rate $=20/\min$.

The volume (in litre) of air that its lungs displace in $24$ hours is-

The amount of air that is left behind in lungs after expiratory reserve volume has been exhaled is

Study the following (consider maximum values)
A) Inspiratory Reserve Volume (IRV)
B) Tidal Volume (TV)
C) Vital capacity (VC)
D) Total Lung Capacity (TLC)
E) Residual Volume (RV)

Arrange the above volumes of air in ascending order

Study the following respiratory volumes(mL) and arrange on decreasing order.
I) Inspiratory reserve volume
II) Tidal volume
III) Inspiratory capacity
IV) Residual volume
V) Expiratory reserve volume
