oxygenation - answer-oxygen molecules move across a membrane from an area of
hugh oxygen concentration to an area of low oxygen concentration
adequate breathing rates - answer-adults (8-24)
elderly (20-22)
children (15-30)
infants (25-50)
right atrium - answer-receives oxygen-depleted blood from the veins
left atrium - answer-receives oxygen-rich blood from the pulmonary veins from lungs
right ventricle - answer-pumps oxygen-depleted blood to pulmonary veins then to lungs
for oxygenation
left ventricle - answer-pumps oxygen-rich blood to aorta and then to the body
tricuspid valve - answer-between the right atrium and the right ventricle
pulmonary valve - answer-at the base of the pulmonary artery in the right ventricle
mitral valve - answer-between the left atrium and left ventricle
aortic valve - answer-at the base of the aortic artery in the left ventricle
arteries - answer-carry oxygen-rich blood away from the heart to the capillaries (except
pulmonary artery)
arterioles - answer-carry blood from arteries in capillaries
capillaries - answer-where exchanges of gases, nutrients, and wastes occur
, hydrostatic pressure - answer-force exerted on the inside of the vessel walls as a result
of blood pressure and volume
edema - answer-swelling due to increased hydrostatic pressure causing capillaries to
leak fluid
perfusion - answer-delivery of oxygen, glucose, and other nutrients to the cells of all
organ systems, and the elimination of carbon dioxide and other wastes
hypoperfusion - answer-insufficient supply of oxygen and other nutrients to some of the
body's cells and the inadequate elimination of carbon dioxide/other wastes
sympathetic nervous system - answer-fight or flight response
parasympathetic nervous system - answer-rebalances body to normal functions
aerobic metabolism - answer-the breakdown of molecules through a series of reactions
that produce energy within the cells in the presence of oxygen
anaerobic metabolism - answer-breakdown of molecules in the cells without the
presence of oxygen with production of limited ATP
patent airway - answer-one that is open and not obstructed by blood, secretions, vomit,
tissue, bone, or any other substance
minute ventilation - answer-the amount of air moved in and out of the lungs in one
minute (tidal volume x frequency ventilations)
average minute ventilation - answer-500mL x 12/minute
cardiac output - answer-heart rate x stroke volume
stroke volume - answer-volume of blood ejected by the left ventricle with each
contraction
preload - answer-pressure generated in the left ventricle after diastole
afterload - answer-the resistance in the aorta that must be overcome by contraction of
the left ventricle to eject blood
auscultating lungs - answer--second intercostal space two inches blew clavicle and at
the midclavicular line
-fourth or fifth intercostal space on midaxillary line
-fifth intercostal space next to the sternum
