RESPIRATORY SYSTEM
CHAPTER 16
Objectives:
11.0 Identify structures and functions of
the respiratory system.
11.1 Tracing the pathway of the oxygen
and carbon dioxide exchange
11.2 Recognizing common disorders of the
respiratory system
Introduction
• What are the two main functions of
the respiratory system?
• Other functions of respiratory
organs include:
– Trapping particles in incoming air
– Controlling temperature and moisture of
incoming air
– Producing vocal sounds
– Aiding in sense of smell
– Regulation of blood pH
Introduction, continued…..
• Respiration: the ENTIRE process of
gas exchange between the
atmosphere and body cells:
1. Movement of air into and out of lungs
(ventilation)
2. Gas exchange between the air in the lungs and
the blood (external respiration)
3. Gas transport by the blood between the lungs
and the body cells
4. Gas exchange between the blood and the body
cells (internal respiration)
