Taking a deep breath, holding it by closing the glottis, and then contracting the abdominal muscles to raise abdominal pressure and push the organ contents out.
Ventral Respiratory Group
The primary generator of the respiratory rhythm; utilizes INSPIRITORY (I) NEURONS and EXPIRATORY (E) NEURONS):
Dorsal Respiratory Group
What issues output to the Ventral Respiratory Group (VRG) that modifies the respiratory rhythm to adapt to varying conditions (conditions outside of normal resting respiratory rhythm)?
What receives input from hypothalamus, limbic system, and cerebral cortex; issues output to both the DRG and VRG; hastens or delays the transition from inspiration to expiration, adapting breathing to special circumstances such as sleep, exercise, vocalization, and emotional responses?
State the appropriate law: The pressure of a given quantity o f gas is inversely proportional to its volume (assuming a constant temperature)
State the appropriate law: The volume of a given quantity of gas is directly proportional to its absolute temperature (assuming a constant temperature)
State the appropriate law: The total pressure of a gas mixture is equal to the sum of the partial pressures of its individual gases.
State the appropriate law: At the air-water interface, the amount of gas that dissolves in water is determined by its solubility in water and its partial pressure in the air (assuming a constant temperature).
Inspiratory Reserve Volume
Amount of air in excess of tidal volume that can be inhaled with maximum effort:
Expiratory Reserve Volume
Amount of air in excess of tidal volume that can be exhaled with maximum effort:
Amount of air remaining in the lungs after maximum expiration; the amount that can never voluntarily be exhaled:
The amount of air that can be inhaled and then exhaled with maximum effort; the deepest possible breath
Alveolar Ventilation Rate
The measurement that is most directly relevant to the body's ability to get oxygen to the tissues and dispose of carbon dioxide:
