Pulmonary Ventilation

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

Which process of external respiration involves the exchange of oxygen and carbon dioxide between lung air spaces and blood?

Which component of the respiratory system functions in conducting air from the larynx to the lungs?

Which of the following is NOT a primary pressure associated with ventilation?

Which of the following lung volumes represents the amount of air that can be forcefully exhaled after a maximum inhalation?

What is the measure of the percentage of the forced vital capacity that can be exhaled within a certain time frame?

What is the total amount of air that flows into or out of the respiratory system in a minute?

Which of the following is a component of external respiration?

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

The smallest airways in the conducting zone are

Surfactant is secreted by

Respiratory System Functions

The respiratory system does not filter nutrients from the blood.

External Respiration

The process of external respiration that involves the exchange of oxygen and carbon dioxide between lung air spaces and blood is called gas exchange.

Respiratory System Components

The trachea functions in conducting air from the larynx to the lungs.
The smallest airways in the conducting zone are terminal bronchioles.

Ventilation Pressures

The primary pressures associated with ventilation are intrapleural pressure, intra-alveolar pressure, and transpulmonary pressure.
The pressure that is NOT associated with ventilation is hydrostatic pressure.

Lung Volumes

The Forced Expiratory Volume (FEV) represents the amount of air that can be forcefully exhaled within a certain time frame.
The Forced Vital Capacity (FVC) represents the amount of air that can be forcefully exhaled after a maximum inhalation.

Respiratory Volumes

The total amount of air that flows into or out of the respiratory system in a minute is called the minute ventilation.

External Respiration Components

Inspiration is a component of external respiration.

Conducting Zone Functions

The conducting zone of the respiratory system is responsible for warming, humidifying, and filtering the air we breathe.
The conducting zone does not exchange oxygen and carbon dioxide.

Surfactant

Surfactant is secreted by type II alveolar cells.
