Question

1. Beth is born with an unusual disease that increases the contractility of her diaphragm. We expect that this will NOT influence her:

A) ERV (expiratory reserve volume)

B) TLC (total lung capacity)

C) FRC (functional residual capacity)

D) Residual Capacity

2. Rick lives in Denver, and exercises daily. How does that altitude alter is lungs:

a) increases inspiratory capabilities

b) increases expiratory capabilities

c) decreases inspiratory capabilities

d) altitude has no effect on the lungs

3. On a spirogram, the waves with the largest amplitude typically refer to the

a) inspiratory capacity

b) total lung capacity

c) vital capacity

d) residual volume

Explanation / Answer

1 answer is option C functional residual capacity

Because FRC is calculated by residual volume and expiratory reserve volume.

Here no effect on both these indicator , diaphagrm contractility affects tidal volume and inspiratory volume depend on diaphragm contraction.

2 answer is A increase inspirational capacity because at high altitude exercise will increase respiratory rate and already there is low atmosphere pressure of o2 which further lead to hypoxia that will increase pulmonary ventilation.

3 answer is C vital capacity which is equal to inspiratory reserve volume and tidal volume and expiratory reserve volume. So its peak is highest.
