Respiratory Physiology Quiz

What is the amount of air moved in or out during normal breathing?

• Inspiratory Reserve Volume (IRV)

• Expiratory Reserve Volume (ERV)

• Tidal Volume (TV)

• Residual Volume (RV)

Which of the following volumes represents the extra air that can be exhaled after a normal breath?

• Inspiratory Reserve Volume (IRV)

• Expiratory Reserve Volume (ERV)

• Vital Capacity (VC)

• Functional Residual Capacity (FRC)

What is the name of the air that remains in the lungs after maximal exhalation?

• Tidal Volume (TV)

• Inspiratory Reserve Volume (IRV)

• Expiratory Reserve Volume (ERV)

• Residual Volume (RV)

What defines the Functional Residual Capacity (FRC)?

• Air remaining in the lungs after a normal exhalation

• Maximum air exhaled after maximal inhalation

• The sum of two or more lung volumes

• Air remaining after maximal inhalation

Which of the following systems delivers deoxygenated blood to the lungs?

• Pulmonary arterial system

• Bronchial arteries

• Systemic circulation

• Coronary circulation

Gas exchange in the alveoli occurs due to what process?

• Active transport

• Diffusion

• Osmosis

• Filtration

Which of the following primarily affects carbon dioxide elimination during ventilation?

• Alveolar-capillary shunt

• Dead-space ventilation

• Diffusion limitation

• Pulmonary embolism

What does the term 'compliance' refer to in lung mechanics?

• The volume of air moved during breathing

• The ease of lung expansion

• The total lung capacity

• The resistance to airflow in the airways

What happens when a patient is under general anesthesia in terms of lung mechanics?

• Lung compliance increases

• There is a decrease in functional residual capacity

• There is an increase in lung volume

• Breathing becomes more efficient

Which of the following situations can lead to a shunt in the alveolar-capillary unit?

• pulmonary embolism

• foreign body obstructing the airway

• blocked blood vessel

• Increased ventilation with no perfusion
