CHAP 6 Flashcards
Pathophysiology
the study of how disease processes affect the function of the body
metabolic
the cellular function of converting nutrients into energy.
electrolyte
a substance that, when dissolved in water, separates into charged particles
aerobic metabolism
the cellular process in which oxygen is used to metabolized glucose. Energy is produced in an efficient manner with minimal waste products
anaerobic metabolism
the cellular process in which glucose is metabolized into energy without oxygen
FiO2
fraction of inspired oxygen in the air we breath
patent
open and clear
tidal volume
the volume of air moved in one cycle of breathing
minute volume
the amount of air breathed in during each desperation multiplied by the number of breaths per minute
dead air space
air that occupies the space between the mouth and alveoli but that does not actually reach the area of gas exchange
chemoreceptors
chemical sensors in the brain and blood vessels that identify changing levels of oxygen and carbon dioxide
plasma oncotic pressure
the pull exerted by large proteins in the plasma portion of blood that tends to pull water from the body into the bloodstream
hydrostatic pressure
the pressure within a blood vessel that tends to push water out of the vessel
stretch receptors
sensors in blood vessels that identify internal pressure
systemic vascular resistance SRV
the pressure in the peripheral blood vessels that heart must overcome in order to pump blood into the system
