14 Respiration also known as breathing air always moves from a higher pressure area to a lower pressure areafour key tasks involved in respirationpulmonary ventilationexternal respirationrespiratory gas transportinternal respiration
15 Respiration Boyle’s law as the volume of a gas increases, the pressure of the gas decreases
16 Respiration inspiration (inhalation) expiration (exhalation) diaphragm and intercostal muscles contractthoracic cavity expandsexpiration (exhalation)diaphragm and intercostal muscles relaxthoracic cavity shrinks
23 Dynamic Lung Volume forced expiratory volume in one second forced expiratory volume in one second/forced vital capacity
24 Review and Assessment True or False? 1. The pons and medulla control breathing.2. Static lung volume involves time.3. Muscles contract in inspiration.4. Larger gas volume, higher pressure.5. Gas moves from low to high pressure.
