the brain stem normally triggers breathing by increasing respirations when:

• carbon dioxide levels increase

• oxygen levels increase

• carbon dioxide levels decrease

• nitrogen levels decrease

Loading red blood cells and creating hemoglobin?

• Oxygenation

• Respiration

• Ventilation

• Circulation

Which of the following is true in regards to aerobic metabolism?

• Uses oxygen and proteins and produces carbon dioxide

• Does not use oxygen and produces lactic acid

• Uses oxygen and glucose and produces carbon dioxide

• Uses lactic acid and produces amino acids

What is the double-folded membrane surrounding each lung?

• Pleura

• Pharynx

• Diaphragm

• Rib Cage

What are the smaller branches of the bronchus that enters the lungs and continues to subdivide?

• Trachea

• Bronchioles

• Bronchi

• Respiration

What muscle separates the chest and the abdomen?

• Oxygen

• Diaphragm

• Pleura

• Lobe

What is respiration?

• Humidifying the air that is breathed in

• Moving air into and out of the airway

• The exchange of gases in the alveolar capillaries

• The amount of oxygen you gain when you're sleeping or resting

Match. All start with " The volume of air that___"

• Tidal Volume

• moves through the lungs in 60 seconds.

• Alveolar ventilation

• moves through the lungs in 60 seconds minus the dead space.

• Minute volume

• moves in or out of the lungs during one breath.

• Dead space

• does not reach alveoli and does not participate in gas exchange.

The process of breathing air into the respiratory system and exchanging oxygen and CO2 between the alveoli and the blood vessels surrounding them is _ respiration.

• external
• internal

• lungal

• alveolo-capillary

What is NOT a purpose of the upper airway?

• humidification

• warming

• filtration

• oxygenation
