Term
carbon dioxide
Definition
the gas that we exhale
Term
carbonic acid dissociation
Definition
the breaking up of carbonic acid into Hydrogen ions and carbonate
Term
carbonic anhydrase
Definition
enzyme that reversibly catalyzes the conversion of carbon dioxide and water to carbonic acid
Term
chloride shift
Definition
when chloride ions move into the red blood cells from plasma due to the transfer of carbon dioxide from tissues to the plasma
Term
dorsal respiratory group (DRG)
Definition
Receives influences from external sources (stretch recptors, the pons, chemoreceptors) Modifies the rate and depth of breathing
Term
expiratory reserve volume
Definition
amount of air forcefully expired after expiration of normal tidal volume
Term
external respiration
Definition
part of the respiratory process involving the exchange of gases in the alveoli
Term
functional residual capacity
Definition
air remaining with normal breath, expiratory reserve volume plus the residual volume
Term
gas exchange
Definition
the inhalation and exhalation of gases - oxygen in and carbon out
Term
hemoglobin
Definition
protein molecule in red blood cells that carry the oxygen
Term
inspiratory capacity
Definition
air breathed in normally, tidal volume plus inspiratory reserve volume
Term
inspiratory reserve volume
Definition
amount of air inspired forcefully after inspiration of normal tidal volume
Term
internal respiration
Definition
exchange of the gasses between the cells and the blood
Term
oxygen
Definition
gas the body takes in when we breathe to create ATP energy
Term
partial pressure
Definition
pressure exerted by each gas, directly proportional to the percentage of that gas in the gas mixture
Term
pH
Definition
the level of acidity of basicity on a scale of 1-14. 1 being extremely acidic. 7 being neutral. and 14 being extremely basic
Term
pontine respiratory center
Definition
Modifies rhythm of the ventral respiratory group by outputs to both the VRG and DRG, Adapts breathing to special circumstances such as sleep, exercise, vocalization, and emotional responses
Term
residual volume
Definition
the volume of air remaining in the lungs after maximal exhalation
Term
tidal volume
Definition
volume of air inspired or expired during a normal inspiration or expiration
Term
total lung capacity
Definition
maximum the lungs can hold, sum of inspiratory and expiratory reserve volumes plus the tidal volume and residual volume
Term
ventral respiratory group (VRG)
Definition
Primary generator of the respiratory rhythm
Term
vital capacity
Definition
air inhaled/exhaled with max effort, sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume, all that you can inhale and all that you can exhale
