Respiratory System

Front

Vital Capacity

Back

TV + IRV + ERV (Tidal Volume + Inspiratory Reserve Volume + Expiratory Reserve Volume) - the maximum amount of air a person can exhale after a maximum inhalation.

Front

Breathing rate control centers

Back

Pons and Medulla - these brain structures regulate the rate and depth of breathing.

Front

Diaphragm

Back

A wide muscle that separates the chest cavity from the abdominal cavity and aids in the inflation of the lungs.

Front

Alveoli

Back

Small air sacs in the lungs where gas exchange occurs; they do not have a covering membrane.

Front

Bronchitis

Back

An inflammation of the bronchial tubes that causes a person to have a nagging cough.

Front

Tidal Volume (TV)

Back

The amount of air inhaled or exhaled during normal breathing.

Front

Inspiratory Reserve Volume (IRV)

Back

The additional amount of air that can be inhaled after a normal inhalation.

Front

Expiratory Reserve Volume (ERV)

Back

The additional amount of air that can be exhaled after a normal exhalation.

Front

Total Lung Capacity (TLC)

Back

The total volume of air in the lungs after a maximum inhalation; TLC = TV + IRV + ERV + RV.

Front

Respiratory System

Back

The system responsible for the exchange of gases (oxygen and carbon dioxide) between the body and the environment.
