Compare tidal volume, expiratory reserve volume, inspiratory reserve volume, residual volume, vital capacity, total lung capacity, inspiratory capacity, and functional residual capacity. List the average values for each volume and capacity. answer in paragraph form 150 word limit

Answer

Lung volumes are otherwise called respiratory volumes. It alludes to the volume of gas in the lungs at a given time during the respiratory cycle. Lung capacities are gotten from a summation of various lung volumes. The normal absolute lung capacity of a grown-up human male is around 6 liters of air.

Lung volumes:

Tidal volume is the amount of air inhaled and exhaled during each breath. The value is 500 ml. Inspiratory reserve volume is the amount of air that is taken in forcibly in addition to the tidal volume. The range of IRV is 3100 ml. Expiratory reserve volume is the amount of air that can be exhaled out forcibly in addition to the tidal volume. The value for ERV is 1200 ml. Residual volume is the amount of air that persists even after forceful expiration. This remaining air permits a gaseous exchange between alveoli and blood. The normal value of RV is 1200 ml.

Lung capacities:

Inspiratory capacity is the most extreme volume of air that can be breathed in after a resting state. It is determined by the amount of inspiratory reserve volume and tidal volume. IC = IRV+TV. Total lung capacity is the most extreme volume of air the lungs can oblige or the amount of all volume compartments or volume of air in lungs following max inspiration. The ordinary worth is about 6,000mL. TLC is determined by the summation of the four essential lung volumes (TV, IRV, ERV, RV). Vital capacity is the aggregate sum of air breathed out after maximal inspiration. The worth is about 4800mL and it changes as per age and body size. It is determined by adding tidal volume, inspiratory reserve volume, and expiratory reserve volume. VC = TV+IRV+ERV. Functional residual capacity is the measure of air staying in the lungs toward the finish of an ordinary exhalation. It is determined by including residual and expiratory reserve volumes. The typical worth is around 1800 – 2200 mL. FRC = RV+ERV.
