acute responses key terms

Define acute response

• immediate short term physiological changes to help meet the energy demand of exercise

• changes occurring within the respiratory system that aim to increase the volume of oxygen intake

• changes occurring within the circulatory system that aim to increase the volume of oxygenated blood delivered to the working muscles

• changes occurring within the muscular system at the beginning of exercise

Define respiratory responses

• immediate short term physiological changes to help meet the energy demand of exercise

• changes occurring within the respiratory system that aim to increase the volume of oxygen intake

• changes occurring within the circulatory system that aim to increase the volume of oxygenated blood delivered to the working muscles

• changes occurring within the muscular system at the beginning of exercise

Define cardiovascular responses

• immediate short term physiological changes to help meet the energy demand of exercise

• changes occurring within the respiratory system that aim to increase the volume of oxygen intake

• changes occurring within the cardiovascular system that aim to increase the volume of oxygenated blood delivered to the working muscles

• changes occurring within the muscular system at the beginning of exercise

Define muscular responses

• immediate short term physiological changes to help meet the energy demand of exercise

• changes occurring within the respiratory system that aim to increase the volume of oxygen intake

• changes occurring within the cardiovascular system that aim to increase the volume of oxygenated blood delivered to the working muscles

• changes occurring within the muscular system at the beginning of exercise

Which describe respiratory rate

• number of breaths taken per minute

• volume of air breathed in with each breath

• volume of air breathed in per minute

• respiratory response

• circulatory response

Which describe tidal volume

• number of breaths taken per minute

• volume of air breathed in with each breath

• volume of air breathed in per minute

• respiratory response

• circulatory response

Which describe pulmonary diffusion

• oxygen diffuses across alveoli membrane into capillaries and then into bloodstream

• oxygen diffuses from capillaries across the alveoli membrane

• increased activation of alveoli leads t greater sites of gas exchange

• respiratory response

• increased gas exchange results in increased oxygen uptake

Which describe ventilation

• respiratory rate x tidal volume

• volume of air breathed in with each breath

• volume of air breathed in per minute

• respiratory response

• circulatory response

What is respiratory rate at rest

• 12 breaths/min

• 30 breaths/min

• 45 breaths/min

What is respiratory during moderate exercise

• 12 breaths/min

• 30 breaths/min

• 45 breaths/min
