Expiratory capacity (EC) is the sum of ________ and ________.

A) expiratory reserve volume (ERV) ; residual volume (RV)
B) tidal volume (TV) ; expiratory reserve volume (ERV)
C) inspiratory reserve volume (IRV) ; expiratory reserve volume (ERV)
D) tidal volume (TV) ; inspiratory reserve volume (IRV)
E) tidal volume (TV) ; residual volume (RV)

Learning Objectives

• Identify and explain various respiratory volumes and capacities, such as tidal volume, expiratory reserve volume, inspiratory reserve volume, and residual volume.
• Acquire the ability to determine and analyze the association among respiratory volumes and capacities, like functional residual capacity, vital capacity, and total lung capacity.
