Question | Answer |
tidal volume | 500ml amt of air u move in or out in a single respiratory cycle |
residual volume | 1200ml amt of air left in lungs after max exhale |
total lung capacity | 5800ml add tidal & residual together |
Inspiration | muscle contract->increases volume of thoracic cavity->intrapleural pressure->lungs expand->intrapulmonary pressure decreases->air into lungs |
Expiration | muscles relax->decrease volume in thoracic cavity->increases intrapleural pressure->lungs recoil->intrapulmonary pressure increases->air out of lungs |
spirograph | graph the changes in volume in the lungs |
vital lung capacity | max inhale/exhale of the lungs |
carbon monoxide poisoning | symptoms: confused, throbbing headache, flushed/red given hyperbaric therapy CO competes for same site as hg as O2 hemoglobin has 200x greater affinity for CO than O2 |
hypoxia | inadequate delivery of O2 to tissues different types due to different causes |
DRG | dorsal respiratory group alters in response to input of inspiration |
VRG | has inspiratory & expiratory centers |
