Which of the following is NOT a function of the respiratory system?

Regulation of body temperature

Explanation

Respiratory system does not regulate body temperature.

Which structure is NOT part of the lower respiratory tract?

Pharynx

Explanation

Pharynx is not part of the lower respiratory tract.

Which of the following is NOT a respiratory disease?

Arthritis

Explanation

Arthritis is not a respiratory disease.

What is the term for the process of air moving into and out of the lungs?

Ventilation

Explanation

Ventilation is the process of air movement into and out of the lungs.

Which of the following is NOT a component of the respiratory membrane where gas exchange occurs?

Bronchial smooth muscle

Explanation

Bronchial smooth muscle is not part of the respiratory membrane for gas exchange.

What is the term for the process of breaking down glucose to produce ATP in the absence of oxygen?

Glycolysis

Explanation

Glycolysis is the breakdown of glucose to produce ATP without oxygen.

What is the term for the volume of air inspired or expired during normal breathing?

Tidal volume

Explanation

Tidal volume is the volume of air exchanged during normal breathing.

Which of the following factors primarily determines the rate of gas diffusion across the respiratory membrane?

Partial pressure gradient of gases

Explanation

The partial pressure gradient of gases drives gas diffusion across the respiratory membrane.

Which of the following is NOT a primary function of the conducting zone of the respiratory system?

Gas exchange

Explanation

The conducting zone is not involved in gas exchange.

#10

During inspiration, which of the following muscles contract to increase the volume of the thoracic cavity?

Diaphragm and external intercostals

Explanation

Diaphragm and external intercostals contract during inspiration to increase thoracic cavity volume.

#11

Which gas is primarily transported in the blood by binding to hemoglobin?

Oxygen

Explanation

Oxygen is primarily transported in the blood by binding to hemoglobin.

#12

Which respiratory disorder is characterized by the collapse of part or all of a lung due to the loss of negative intrapleural pressure?

Pneumothorax

Explanation

Pneumothorax is the collapse of a lung due to loss of negative intrapleural pressure.

#13

Which respiratory center in the brain is responsible for setting the basic rhythm of breathing?

Medullary respiratory center

Explanation

The medullary respiratory center sets the basic rhythm of breathing.

#14

Which respiratory disease is characterized by inflammation and narrowing of the airways, leading to wheezing, coughing, and shortness of breath?

Asthma

Explanation

Asthma is characterized by airway inflammation and narrowing.

#15

Which of the following is NOT a factor that can affect lung compliance?

Airway resistance

Explanation

Airway resistance does not affect lung compliance.

#16

Which respiratory disorder is characterized by a chronic, irreversible decrease in airflow due to a combination of emphysema and chronic bronchitis?

Chronic obstructive pulmonary disease (COPD)

Explanation

COPD is characterized by chronic, irreversible airflow decrease.

#17

Which of the following is NOT a factor that affects the rate of gas diffusion across the respiratory membrane?

Solubility of gases in the blood

Explanation

Solubility of gases in the blood is not a factor affecting gas diffusion across the respiratory membrane.
