Respiratory Flashcards
reverse
the volume of gas that reaches the alveolar region of the lung
alveolar ventilation
reverse
microscopic air sacks located in the lung
alveoli
reverse
the total volume of the lung that does not participate in gas exchange
anatomical dead space
reverse
receptors located in the arch of the aorta that are capable of detecting changes in arterial PO2
aortic bodies
reverse
right shift of the oxyhemoglobin dissociation curve due to a decrease in blood pH
Bohr effect
reverse
mass movement of molecules from high pressure area to low pressure area
bulk flow
reverse
chemoreceptors located in the internal carotid artery
carotid bodies
reverse
process of oxygen consumption and carbon dioxide production in cells
cellular respiration
reverse
hemoglobin not in combination with oxygen
deoxyhemoglobin
reverse
major respiratory muscle responsible for inspiration
diaphragm
reverse
random movement of molecules from an area of high concentration to an area of low concentration
diffusion
reverse
red blood cell responsible for transporting oxygen
hemoglobin
reverse
protein in muscle that can bind oxygen and release it at low PO2 values
myoglobin
reverse
hemoglobin combined with oxygen
oxyhemoglobin
reverse
fractional part of the barometric pressure due to the presence of a single gas
partial pressure
reverse
thin lining of cells that is attached to the inside of the chest wall and to the lung
pleura
reverse
refers to ventilation of the lung
pulmonary respiration
reverse
volume of air in the lungs following a maximal experation
residual volume (RV)
reverse
The exchange of oxygen and carbon dioxide between the lungs and the enviorment
respiration
reverse
measurement of varied lung volumes
spirometry
reverse
volume of air inhaled or exhaled in a single breath
tidal volume
reverse
total volume of air the lung can contain
total lung capacity (TLC)
reverse
movement of air into or out of the lungs
ventilation
reverse
the breakpoint at which pulmonary ventilation and carbon dioxide output increase exponentially during an incremental exercise test
ventilatory threshold
reverse
volume of air that can be moved into or out of the lungs in one breath
vital capacity
reverse
compounds capable of giving up hydrogen ions into a solution
acid
reverse
an abnormal increase in blood hydrogen ion concentration
acidosis
reverse
an abnormal increase in blood concentration of OH- ions, resulting in a rise in arterial pH
alkalosis
reverse
compounds that ionize in water
base
reverse
compound that resists pH change
buffer
reverse
free hydrogen ion in solution that results in a decrease in pH of the solution
hydrogen ion
reverse
a single atom or small molecule with a charge of either positive or negative
ion
reverse
a measure of the acidity of a solution
pH
reverse
the buffering of excess H+ in the blood by plasma bicarbonate, and associated elevation in ventilation to exhale the resulting CO2
respiratory compensation
reverse
acid that completely ionizes causing an anion
strong acids
reverse
a base that completely dissolves resulting in a cation
strong bases
reverse
The total pressure of a mixture of gases equals the sum of the partial pressures of the individual gases in the mixture.
Daltons Law
reverse
Gases dissolve in liquids in proportion to their partial pressures, depending on their solubility in the specific fluids and depending on the temperature.
Henrys Law
Shortness of breath
Dyspnea
Increase in ventilation that exceeds the metabolic need for oxygen
Hyperventilation
Point during graded exercise at which the rate of anaerobic metabolism exceeds the rate of aerobic metabolism
Anaerobic Threshold
The point during intense exercise at which ventilation increases disproportionately to the oxygen consumption
Ventilatory Breakpoint
A contraction of the muscles surrounding the air passages, which narrows these passages and causes wheezing, shortness of breath and heaviness in the chest
Asthma
the ability of blood (and/or) muscle to resist changes in pH when acids are either added or removed
Buffer Capacity
