Respiratory System Quiz Review

These flashcards cover key concepts related to lung volumes, pressures during inspiration, and the effects of exercise on the respiratory system.

Thoracic Volume during Inspiration

During inspiration, thoracic volume increases.

Pressure during Inspiration

During inspiration, pressure decreases.

Effect of Holding Breath

Holding your breath causes a build-up of CO2 in your body.

Blood pH with CO2 Build-up

A build-up of CO2 leads to an increase in H+ concentration and a decrease in blood pH.

Effect of Hypoventilation on CO2

Hypoventilation causes CO2 to increase.

Effect of Hypoventilation on Blood pH

Hypoventilation leads to a decrease in blood pH.

Volumes used to calculate Vital Capacity

Vital Capacity is calculated using Tidal Volume, Inspiratory Reserve Volume, and Expiratory Reserve Volume.

Diaphragm during Inspiration

During inspiration, the diaphragm contracts.

Residual Volume

Residual volume is the amount of air remaining in the lungs after a full exhalation.

Vital Capacity

Vital capacity is the maximum amount of air a person can forcefully exhale after a full inhalation.

Inspiratory Reserve Volume (IRV)

Inspiratory Reserve Volume is the volume of air that can be forcefully inhaled after a normal tidal inspiration.

Expiratory Reserve Volume (ERV)

Expiratory Reserve Volume is the volume of air that can be forcefully exhaled after a normal tidal expiration.

Lung Volumes during Exercise - Tidal Volume

During exercise, tidal volume increases.

Lung Volumes during Exercise - Expiratory Reserve Volume

During exercise, expiratory reserve volume decreases.

Lung Volumes during Exercise - Inspiratory Reserve Volume

During exercise, inspiratory reserve volume decreases.

Total Lung Capacity during Exercise

Total lung capacity stays the same during exercise.
