What are the three primary functions of the respiratory system?

• Producing speech through airflow

• Exchanging carbon dioxide for oxygen

• Exhalation of carbon dioxide and waste from the body

• Filtering air entering the body

• Inhalation of oxygen rich air

Which of the following is a secondary function of the respiratory system?

• Exchanging carbon dioxide for oxygen

• Expelling waste products from the bloodstream

• Producing airflow for speech

• Bringing oxygen-rich air into the body

The process of taking in air is (a)   while the process of breathing air out of the lungs is ​ (b)  

• inhalation
• exhalation
• ventilation
• external respiration

What occurs during external respiration in the respiratory system?

• Oxygen is released from cells into the bloodstream

• Carbon dioxide is inhaled into the lungs for exchange

• Oxygen is carried to cells by erythrocytes during inhalation

• Carbon dioxide is expelled from cells during exhalation

Which gas is primarily involved in external respiration during each inhalation?

• Nitrogen

• Oxygen

• Carbon dioxide

• Hydrogen

What is the fate of carbon dioxide during external respiration in the lungs?

• It is carried to cells by erythrocytes during inhalation

• It is converted into oxygen during exhalation

• It passes from capillaries into the lungs to be exhaled

• It is stored in the alveoli for later use

What best describes the process of internal respiration in the human body?

• Gas exchange that occurs at the cellular and tissue levels

• Exchange of gases between the lungs and the bloodstream

• Movement of oxygen from the air sacs to the bloodstream

• Transportation of carbon dioxide from tissues to the lungs for exhalation

What is the correct method for counting respiratory rate without announcing it to the patient?

• Observe the patient's breathing while holding their wrist to count the respirations.

• Take the pulse, then without letting go, use peripheral vision to observe one cycle of breathing, counting it as one respiration.

• Ask the patient to inform you of their breathing rate while checking their pulse.

• Announce that you are observing their breathing to ensure an accurate count.
