The Respiratory System - Chapter Summary and Learning Objectives

It's easy to take our respiratory system for granted when everything is working well. But when breathing difficulties need to be addressed, it's important to see a specialist. While some respiratory system problems can be cleared up with medication or other therapies, others become chronic conditions that require regular interventions, such as medication or surgery. The anatomy and physiology of the respiratory system is actually very involved and includes the nose, trachea, pharynx, larynx, and lungs. In these lessons, you'll learn things like:

  • Anatomy and physiology of the respiratory system
  • Common illnesses, diseases, and conditions of the respiratory system
  • Common treatments of respiratory illnesses and diseases
  • What respiratory specialists do
