False - ANSWER-true or false: One of the primary limitations to exercise capacity is ventilation. True - ANSWER-True or false: The initial response of the respiratory system to exercise is to increase VT and Fb True - ANSWER-True or False: PCO2 is more important than PO2 in ventilation regulation epinephrine - ANSWER-Which hormone stimulates the sympathetic nervous system increase body temp, motor impulses from the cerebral cortex, and levels of catecholamines - ANSWER-what plays a role in increasing ventilation during exercise?

Page 2/9 True - ANSWER-True or false: there may be a 20-30 fold increase in ventilation over resting values during strenuous exercise/ The anaerobic threshold is reached - ANSWER-Expired ventilation increases linearly with exercise vo2 until... false - ANSWER-True or false: endurance training significantly increases tidal volume at rest. False - ANSWER-True or false: during expiration the diaphragm is contracting. midbrain, pons, medulla oblongata - ANSWER-What does the brainstem consist of? passive expiration - ANSWER-lungs expel air when alveolar pressure is higher than the atmospheric pressure Tidal Volume (VT) - ANSWER-Amount of air moved per breath active expiration - ANSWER-a forced exhalation using the abdominal wall, internal intercostal muscles, and diaphragm. partial pressure - ANSWER-the part of the total pressure exerted by a gas. 70% by contraction of the diaphragm and 30% by tidal volume change - ANSWER- how is normal breathing accomplished? 3-5% of energy expenditure - ANSWER-how much energy is used at rest for air flow?

Page 3/9 medulla oblongata - ANSWER-Part of the brainstem that controls vital life- sustaining functions such as heartbeat, breathing, blood pressure, and digestion. medullary respiratory center - ANSWER-A collection of neurons in the reticular formation of the medulla involved in establishing or modifying the pattern of breathing dorsal respiratory group (DRG) - ANSWER-Formerly the expiratory center; neurons in the medulla that generate the rhythm of breathing in response to the physiological needs of the body. The DRG neurons are primarily responsible for inspiration - ANSWER-What is the primary responsibility of the DRG? during the on, neurons of the DRG cause the inspiratory muscles to contract. During the off, neurons of the DRG stop firing. the inspiratory muscle
