PP
V/Q Match
ventilation/perfusion match
implies that the alveoli are supplied with enough air and that the air in the alveoli is matched with sufficient blood in the pulmonary capillaries to permit optimum exchange of oxygen and carbon dioxide
Systemic Vascular Resistance
pressure in the peripheral blood vessel that the heart must overcome to pump blood into the system
The amount of blood ejected from the heart in one contraction
Stroke volume
Stretch Receptors
sensors in blood vessels that identify internal pressure
Plasma Oncotic
the pull exerted by large proteins in the plasma portion of blood that tends to pull water from the body into the bloodstream
An exaggerated response by the immune system to a particular substance
Hypersensitivity
The supply of oxygen to and removal of wastes from the cells and tissues of the body as a result of the flow of blood through the capillaries
Perfusion
Pathophysiology
the study of how disease processes affect the function of the body
Open and clear; free from obstruction
Patent
Minute Volume
amount of air breathed in during each respiration multiplied by the number of breaths per minute
The volume of air moved in one cycle of breathing
Tidal Volume
The cellar function of connecting nutrients into energy
Metabolism
Hypoperfusion
inability of the body to adequately circulate blood to the body's cells to supply them with oxygen and nutrients
life-threatening condition
also called shock
Electrolyte
substance that when dissolved in water, separates into charged particles
Edema
swelling associated with the movement of water into the interstitial space
Hydrostatic
the pressure within a blood vessel that tends to push water out of the vessel
fraction of inspired oxygen; the concentration of oxygen in the air we breath
Diaphoresis
sweating; condition of cool, pale, and moist skin
An abnormally low amount of water in the body
Dehydration
Dead air space
Chemoreceptors
chemical sensors in the brain and blood vessels that identify changing levels of oxygen and carbon dioxide
The amount of blood ejected from the heart in one minute
Heart rate-stroke volume
Cardiac output
The cellular process in which glucose is metabolized into energy without oxygen. Energy is produced in an inefficient manner, with any waste product
Anaerobic
Aerobic
the cellular process in which oxygen is used to metabolize glucose. Energy is produced in an efficient manner, with minimal waster products
