Review Take out a piece of paper and answer these questions 1.How is breathing related to cellular respiration? 2. How did exercise affect the rate of cellular respiration? How can bromothymol blue pH help you measure the rate of cellular respiration?
A closer look at the mechanics video
Respiration investigation In this activity you will measure and monitor breathing rates to better understand respiration, inspiration, and lung capacity Grab a worksheet from the front: 1 per table Grab a balloon from the front: 1 per table Answer the questions and write down results on a separate sheet of paper: 1 per table
Respiration: Mechanics and Control Chapter 9: The Respiratory System Lesson 2 Respiration: Mechanics and Control
Respiration: Mechanics and Control nonrespiratory air maneuvers control of breathing lung volume
Respiration also known as breathing air always moves from a higher pressure area to a lower pressure area four key tasks involved in respiration pulmonary ventilation external respiration respiratory gas transport internal respiration
Respiration Boyle’s law as the volume of a gas increases, the pressure of the gas decreases
Respiration inspiration (inhalation) expiration (exhalation) diaphragm and intercostal muscles contract thoracic cavity expands expiration (exhalation) diaphragm and intercostal muscles relax thoracic cavity shrinks
Respiration
Nonrespiratory Air Maneuvers
Control of Breathing neural factors chemical factors pons and medulla oblongata chemical factors central chemoreceptors peripheral chemoreceptors mechanoreceptors
Control of Breathing
Lung Volume static dynamic air volume in lungs air volume in lungs based on time
Static Lung Volume tidal volume vital capacity residual volume functional residual capacity inspiratory reserve volume expiratory reserve volume total lung capacity
Dynamic Lung Volume forced expiratory volume in one second forced expiratory volume in one second/forced vital capacity
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.
