32. 呼吸容積(respiratory volume)有四種，(1)潮氣容積(tidal volume, TV) (2)吸氣儲備容積(inspiratory reserve volume, IRV) (3)呼氣儲備容積(expiratory reserve volume, ERV) (4)肺餘容積(residual volume, RV)。有關肺容量(lung capacity)的敘述，下列何者有誤？
(A) 吸氣容量(inspiratory capacity) = (1) + (2)
(B) 功能肺餘量(functional residual capacity) = (1) + (3)
(C) 肺活量(vital capacity) = (1) + (2) + (3)
(D) 肺總量(total lung capacity) = (1) + (2) + (3) + (4)
