Exercise 6: The Respiratory System

Objectives

• Identify Anatomy

  • Gross and microscopic structures of upper and lower respiratory tracts.

• Respiratory Process

  • Outline the steps that lead to respiration including relevant laws governing respiration.

• Muscle Function

  • Explain the role and function of muscles involved in the process of breathing.

• Respiratory Volumes and Capacities

  • Define and measure respiratory volumes and capacities, including calculations.

• Clinical Applications

  • Apply learned concepts by reviewing clinical case studies relevant to the respiratory system.

Introduction to the Respiratory System

• The respiratory system works in conjunction with the cardiovascular system for:

  • Oxygen delivery to the body.

  • Carbon dioxide removal from bodily tissues.

• Gas Exchange Function

  • Facilitates the exchange of oxygen and carbon dioxide with the external environment.

• Anatomical Segregation

  • Respiratory structures categorized into:

    • Upper Respiratory Tract

      • Comprises: nose, nasal cavity, paranasal sinuses, and pharynx.

      • Utilize Figure 6.1 and Table 6.1 for structural identification in lab models.

    • Lower Respiratory Tract

      • Comprises: larynx, trachea, and bronchial tree.

      • Guided by Figures 6.1, 6.2, 6.3 and Table 6.2 for identification in model and microscope slides in the lab.
