11. Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. also known as breathing air always moves from a higher pressure area to a lower pressure area Boyle’s law –as the volume of a gas increases, the pressure of the gas decreases Respiration

12. Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. four key tasks involved in respiration –pulmonary ventilation Moving air in & out of lungs –external respiration Fresh outside oxygen fills lungs – gas exchange between alveoli & capillary beds –respiratory gas transport O2 & CO2 transported between lungs & body tissues –internal respiration Gas exchange between capillaries & body cells Respiration

13. Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. inspiration (inhalation) –diaphragm and intercostal muscles contract –thoracic cavity expands expiration (exhalation) –diaphragm and intercostal muscles relax –thoracic cavity shrinks Respiration
