Exam 2 Flashcards
Transfer of air between blood and lungs
Pulmonary Ventilation
gas exchange between alveoli and capillaries
Pulmonary Diffusion
Form of internal respiration which is gas moving between blood vessels and metabolic cells such as muscles
Capillary Diffusion
Amount of air entering and leaving the lungs with each normal breath
Tidal Volume
Amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible
Forced vital capacity
Volume of air remaining in the lungs after a maximal exhalation
Residual Lung Volume
Volume of gas inhaled or exhaled from a person’s lungs per minute
(tidal volume x respiratory rate)
Minute Ventilation
Refers to amount of gas that reaches the alveoli during a breath
Alveolar Ventilation
Refers to the rest of the gas taken in during a breath that stays in spaces not capable of gas exchange, like the trachea and conducting airways
Dead Space Ventilation
Vital Capacity + Residual Volume
Total Lung Capacity
greatest amount of air that can be expired after a max inspiration
Vital Capacity
volume of air remaining in lungs after normal expiration
Functional Residual Volume
amount of air remaining in lungs after a max expiration
Residual volume
gases dissolve in liquids in proportion to partial pressure
Henry’s Law
total volume of blood pumped per minute
Q = HR x SV
Cardiac Output
