Aerobic metabolism
|
The cellular process in which oxygen is used to metabolize glucose. Energy is produced in an efficient manner with minimal waste product.
|
|
|
anaerobic metabolism
|
the cellular process in which glucose is metabolized into energy without oxygen. energy is produced in an inefficient manner with waste products.
|
|
|
Cardiac output
|
the amount of blood ejected from the heart in 1 minute (heart rate x stroke volume)
|
|
|
Chemoreceptor
|
chemical sensors in the brain and blood vessels that identify changing levels of oxygen and carbon dioxide
|
|
|
Dead air space
|
air that occupies space between the mouth and alveoli but does not actually reach the area of gas exchange
|
|
|
Dehydration
|
an abnormally low amount of water in the body
|
|
|
Adema
|
swelling associated with the movement of water into the interstitial space
|
|
|
Electrolyte
|
a substance that, when dissolved in water, separates into charge particles
|
|
|
Fio2
|
fraction of inspired oxygen; the concentration of ogygen in the air
|
|
|
Hydrostatic pressure
|
the pressure within a blood vessel that tends to push water out of the vessel
|
|
|
Hypersensitivity
|
an exaggerated response by the immune system to a particular substance
|
|
|
Hypoperfusion
|
inability of the body to adequantely circulate blood to the bodys cells to supply the with oxygen and nutrients. also called shockswa
|
|
|
Minute volume
|
the amount of air breathed in during each respiration multiplied by the number of breath per minute
|
|
|
pathophysiology
|
the study of disease processes affect the function of the body
|
|
|
Perfusion
|
the supply of oxygen to, and removal of wastes from, the cells and tissue of the body as a result of the flow blood through the capillaries
|
|
|
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
|
|
|
Shock
|
the inability of the body to adequarely circulate blood to the bodys cells to supply them with oxygen and nutrients. also called hypoperfusion a life threatening condition
|
|
|
Stretch receptors
|
sensors in blood vessels that identify internal pressure
|
|
|
Stroke volume
|
the amout of blood ejected from the heart in one contraction
|
|
|
Systemic vascular
|
the pressure in the peripheral blood vessels that the heart must overcome in order to pump blood into the system
|
|
|
Tidal volume
|
the volume of air moved in one cycle of breathing
|
|
|
V/Q match
|
ventilation/perfusion match. this implies that the alveoli are supplied with enough air and that the air in the aveoli is matched with sufficient blood in the pulmanary capillaries to permit optimum exchange of oxygen and carbon dioxide
