Week 6 Respiratory System-Anatomy
Learning Objectives:
Describe the gross anatomical features of the respiratory tract.
Trace the flow of air into and out of the lungs.
Explain how Boyle’s law relates to the changing intrapleural and alveolar air
pressures and volumes during respiration.
Define various pulmonary volumes.
Introduction:
The respiratory tract carries air to and from the lungs. Air drawn in through the nose or mouth
passes through the pharynx and larynx and continues through the trachea, bronchial tree, and
the lungs.
Inhalation relies on decreasing the pressure in the lungs below the atmospheric pressure to
draw air in. Pressure in the lungs is decreased by increasing the volume of the thoracic cavity;
The lungs move with the chest wall because the cavities which contain them are closed spaces.
Each lung is protected by a double membrane called the pleural membrane.
We can assess a person’s lung function by performing spirometry which allows us to measure
pulmonary volumes. Don’t hold your breath, let’s go learn about this essential system!
Assignment:
Part 1 Complete the activities in Anatomy.TV Respiratory System: Introduction, Upper and
Lower Respiratory Tract, Pulmonary Ventilation, Lung Volumes and Capacities.
To access Anatomy.TV: Resources tab>Library>Library Resources-Database A-
Z>Anatomy.TV>Titles: Choose Respiratory system>choose assigned sections
You will then work through the material and activities by scrolling down on the right. This will
allow you to see and work through all activities for that section.
As you complete the lab activities, have the lab report ready to record data.
