Respiratory system

What is the correct pathway of the Respiratory system when O₂ enters your body ?

• Nasal cavity -> Pharynx -> Trachea -> Bronchi -> Alveoli

• Nasal cavity -> Trachea -> Pharynx -> Bronchi -> Alveoli

• Pharynx -> Nasal cavity -> Trachea -> Bronchi -> Alveoli

• None of all above

Respiratory activities involves :

• Taking in O₂

• Transporting O₂ to cells

• Removing CO₂

• All of the above

The process by which animals exchange gases with their environment

What occurs to air as it is inspired into the respiratory system?

• Humidified

• Warmed

• Filtered

• All of the above

The vocal chords are found in the

• Larynx

• Alveoli

• Trachea

• Pharynx

Internal respiration occurs at the

• cellular membranes

• nasal and oral cavity

• alveolar membranes

• bronchioles

Of the four parts of respiration, the part when oxygen and carbon dioxide are exchanged in the capillaries lining the alveoli in the lungs, is:

• pulmonary ventilation

• external respiration

• transport of respiratory gases

• internal respiration

Of the four parts of respiration, the part when oxygen and carbon dioxide are exchanged in the body’s tissue cells, is:

• pulmonary ventilation

• external respiration

• transport of respiratory gases

• internal respiration

The organs of the respiratory system include all the following EXCEPT:

• nose

• trachea

• lungs

• body tissues

The organs of the conducting zone of the respiratory system include all the following EXCEPT:

• nose

• trachea

• bronchi

• alveoli
