Understanding the Respiratory System: Functions and Anatomy

Explore the basic functions, anatomy, and medical terms of the respiratory system. Learn about the purpose of the lungs, measurement tools, and how the system supplies oxygen to cells and removes carbon dioxide. Discover the role of the respiratory system in regulating blood pH, sound, speech, and smell. Test your knowledge and understanding of the respiratory system's functions, respiration, and anatomy, including the upper and lower respiratory tract, alveoli, and path of air passage. Dive into respiratory disorders, symptoms, and diagnostic procedures to gain a comprehensive understanding of this vital system.

Presentation Transcript

  1. Chapter Eleven Respiratory System

  2. Learning Outcomes • Describe the purpose of the lungs/respiratory system • Basic functions and anatomy of respiratory system • Medical terms for system • Measurement tools

  3. Functions of the Respiratory System • Supplies oxygen (ox/o) to cells • Removes carbon dioxide (capn/o) • Filtering, cleansing, warming, humidifying air • Regulation of blood pH • Role in sound, speech, and smell

  4. Functions of the Respiratory System • Respiration (spir/o) • Inspiration/inhalation • Expiration/exhalation http://study.com/academy/lesson/alveoli-function-definition-sacs.html The respiratory system: nasal cavity, pharynx, larynx, trachea, bronchus, and lung with expanded views of the trachea and alveolar structure.

  5. Test yourself

  6. Functions of the Respiratory System • Respiration (spir/o) • Inspiration/inhalation • Expiration/exhalation The respiratory system: nasal cavity, pharynx, larynx, trachea, bronchus, and lung with expanded views of the trachea and alveolar structure.

  7. Anatomy and Physiology • Upper respiratory tract • Nose (nas/o, rhin/o) • Pharynx (pharyng/o) • Larynx (laryng/o) • Lower respiratory tract • Trachea (trache/o) • Bronchial tree (bronch/o, bronchi/o) • Lungs (pulmon/o, pneum/o, pneumon/o) Path of air passage from upper to lower respiratory system
