    Week 3: Concepts of Cardiovascular and Respiratory Disorders

    The circulatory system and the respiratory system are powerful partners in health. While they work closely together in good health, a disease or disorder that manifests in one can have a significant impact on both, hampering the pair’s ability to collaborate.

    Cardiovascular and respiratory disease and disorders are among the most common reasons for hospital visits, and among the leading causes of fatality. Heart disease and pneumonias are among the most familiar, but a wide variety of issues can impact physiological functioning of one or both systems.

    This week, you examine fundamental concepts of cardiovascular and respiratory disorders. You explore common diseases and disorders that impact these systems, and you apply the key terms and concepts that help communicate the pathophysiological nature of these issues to patients.

    Learning Objectives

    Students will:

    Analyze concepts and principles of pathophysiology across the lifespan

    Online Media from Pathophysiology: The Biologic Basis for Disease in Adults and Children

    In addition to this week’s media, it is highly recommended that you access and view the resources included with the course text, Pathophysiology: The Biologic Basis for Disease in Adults and Children. Focus on the videos and animations in Chapters 32, 33, 35, and 36 that relate to cardiorespiratory systems and alteration in cardiorespiratory systems. Refer to the Learning Resources in Week 1 for registration instructions. If you have already registered, you may access the resources at
