Upper & Lower Respiratory Tract Infections

Learning Objectives
At the end of this unit, the student will be able to:

  1. Describe the basic anatomy of the respiratory tract and explain the mechanical defenses of each anatomic site and how alterations to these sites may lead to infectious diseases.

  2. Define the importance of normal flora in the respiratory tract and explain how alterations in the normal flora may lead to infectious disease.

  3. Name 5 organisms considered to be normal flora of the upper respiratory tract.

  4. Discuss the basic pathogenic mechanisms of infectious diseases of the respiratory tract and the virulence factors of the organisms that cause disease.
