Respiratory System Quiz

Respiration is the exchange of what between the atmosphere, lungs, blood, and tissue cells?

• Nutrients

• Gases

• Blood cells

• Energy

What does the cardiovascular system assist the respiratory system in doing?

• Transporting nutrients in the blood

• Transporting gases in the blood

• Eliminating waste from the cells

• Absorbing oxygen in the muscles

What are the three steps of gas exchange in the respiratory system?

• Pulmonary ventilation, external respiration, internal respiration

• Pulmonary circulation, systemic circulation, cellular respiration

• Inhalation, exhalation, diffusion

• Bronchial expansion, alveolar exchange, capillary transfer

What is the purpose of pulmonary ventilation in the respiratory process?

• To transport oxygen to the brain

• To circulate blood through the heart

• To facilitate breathing

• To digest food molecules

What is the primary function of external (pulmonary) respiration?

• To convert glucose to ATP

• To exchange gases between the alveoli and blood in the pulmonary capillaries

• To transport oxygen to the systemic tissues

• To remove carbon dioxide from the digestive system

Internal (tissue) respiration involves the exchange of gases between what two components?

• The heart and the systemic capillaries

• The systemic capillaries and tissue cells

• The alveoli and the pulmonary capillaries

• The bronchi and the lungs

Which of the following is part of the upper respiratory tract?

• Larynx

• Trachea

• Bronchi & bronchioles

• Pharynx

What is the primary function of the alveoli in the lungs?

• To produce vocal sounds

• To transport oxygen to the bloodstream

• To filter out dust and pathogens

• To warm and humidify the air

Which structure is responsible for maintaining an open airway to the lungs?

• Esophagus

• Trachea

• Diaphragm

• Epiglottis

Where does gas exchange occur in the respiratory system?

• Trachea

• Bronchi

• Alveoli

• Larynx
