Resp. Vocab

The actual site of gas exchange occurs at the:

• trachea

• nasopharynx

• alveoli

• primary bronchi

Gas exchange occurs when;

• oxygen in the alveoli diffuses into the blood in capillaries

• oxygen binds with hemoglobin in the red blood cells

• the red blood cells give up oxygen to the cells of the body tissues

• All of these

Carbon dioxide is transported in the blood by:

• water molecules (H2O)

• hemoglobin

• bicarbonate ions (HCO3)

• white blood cells

The main function of the respiratory system is:

• to get oxygen

• to get rid of CO2

• Sneezing

• Yawning

• Coughing

• Inspiration

The amount of air that normally moves in and out of the lungs is called

• Tidal Volume

• Residual Volume

• Normalityness

• Vital Capacity

The maximum amount of air that the lungs can hold is called:

• Tidal Volume

• Residual Volume

• Normalityness

• Vital Capacity

The amount of air that stays in the lungs after expiration is called:

• Tidal Volume

• Residual Volume

• Normalityness

• Vital Capacity
