Final answer:
Using the given respiratory volumes, VC is calculated to be 5,800 mL, IC to be 4,300 mL, TLC to be 7,200 mL, and FRC to be 2,900 mL. These calculations are based on the definitions and methods provided for adding together specific respiratory volumes to find various capacities.
Step-by-step explanation:
Calculating Respiratory Capacities
Respiratory capacities are measurements of two or more volumes related to lung function. To calculate the vital capacity (VC), inspiratory capacity (IC), total lung capacity (TLC), and functional residual capacity (FRC), we will use the given values: Tidal Volume (TV) = 550 mL, Inspiratory Reserve Volume (IRV) = 3,750 mL, Expiratory Reserve Volume (ERV) = 1,500 mL, and Residual Volume (RV) = 1,400 mL.
VC (Vital Capacity) is the sum of the Tidal Volume (TV), Expiratory Reserve Volume (ERV), and Inspiratory Reserve Volume (IRV). Therefore, VC = TV + IRV + ERV = 550 mL + 3,750 mL + 1,500 mL = 5,800 mL.
IC (Inspiratory Capacity) is the sum of the Tidal Volume (TV) and Inspiratory Reserve Volume (IRV). Hence, IC = TV + IRV = 550 mL + 3,750 mL = 4,300 mL.
TLC (Total Lung Capacity) is the sum of all the lung volumes (TV, IRV, ERV, and RV). TLC = TV + IRV + ERV + RV = 550 mL + 3,750 mL + 1,500 mL + 1,400 mL = 7,200 mL.
FRC (Functional Residual Capacity) is the sum of the Expiratory Reserve Volume (ERV) and Residual Volume (RV). Therefore, FRC = ERV + RV = 1,500 mL + 1,400 mL = 2,900 mL.
