2680612728Aerobic metabolismThe cellular process in which oxygen is used to metabolize glucose. Energy is produced in an efficient manner with minimal waste0
2680614059Anaerobic metabolismthe cellular process in which glucose is metabolized into energy without oxygen. Energy is produced in an inefficient manner with many waste products.1
2680616119Cardiac outputthe amount of blood ejected from the hear in one minute (heart rate x stroke volume)2
2680617776Chemoreceptorschemical sensors in the brain and blood vessels that identify changing levels of oxygen and carbon dioxide3
2680622299Dead air spaceair that occupies the space between the mouth and alveoli4
2680623240Dehydrationan abnormally low amount of water in the body5
2680625484Diaphoresiscool, pale, and moist/sweaty skin; sweating6
2680628312Edemaswelling associated with the movement of water into the interstitial space7
2680630794ElectrolyteA substance that, when dissolved in water, separates into charge particles8
2680634905FiO2fraction of inspired oxygen; the concentration of oxygen in the air we breathe9
2680640760Hydrostatic pressurethe pressure within a blood vessel that tends to push water out of the vessel10
2680687812Hypersensitivityan exaggerated response by the immune system to a particular substance11
2680647738Hypoperfusioninability of the body to adequately circulate blood to the body's cells to supply them with oxygen and nutrients. A life-threatening condition. Also called shock.12
2680650463MetabolismThe cellular function of converting nutrients into energy13
2680651585Minute volumeThe amount of air breathed in during each respiration multiplied by the numbers of breaths per minute14
2680656758Patentopen and clear; free from obstruction.15
2680658490PathophysiologyThe study how disease processes affect the function of the body.16
2680659896PerfusionThe supply of oxygen to and removal of wastes from the cell and tissues of the body as a result of the flow of blood through the capillaries.17
2680664044Plasma oncotic pressurethe pull exerted by large proteins in the plasma proteins in the plasma portion of the blood that tend to pull water from the body into the bloodstream.18
2680670037Shocksee hypoperfusion19
2680670811stretcher receptorssensors in the blood vessels that identify internal pressure20
2680672841stroke volumethe amount of blood ejected from the heart in one contraction21
2680673546systemic vascular resistancethe pressure in the peripheral blood vessels that the heart must overcome to pump blood into the system22
2680675474tidal volumethe volume of air moved in one cycle of breathing.23
2680677227V/Q matchventilation/perfusion match. This 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 dioxide24
