veins - CORRECT-ANSWERStransport blood to the heart
pulmonary circulation - CORRECT-ANSWERSgas exchange in the lungs
function of plasma proteins - CORRECT-ANSWERSosmotic pressure, antibody,
and blood clots

ANSWERSintermittent claudication (leg pain), weak peripheral distal pulses

arterial wall, develops from defect in the medial layer
signs and symptoms of aortic aneurysm - CORRECT-ANSWERSasymptomatic
until rupture, rupture may lead to moderate bleeding but usually causes
severe hemorrhage and death

superficial veins, in the legs
thrombophlebitis - CORRECT-ANSWERSthrombus development in inflamed
vein
phlebothrombosis - CORRECT-ANSWERSthrombus forms spontaneously
without prior inflammation, attached loosely

systemic circulation - CORRECT-ANSWERSexchange of gases, nutrients, and
wastes in tissues
triad of virchow - CORRECT-ANSWERSvenous stasis
venous endothelial damage
, hypercoagulable states
shock - CORRECT-ANSWERSresults from a decreased circulating blood
volume, leading to decreased tissue perfusion and general hypoxia
hypovolemic shock - CORRECT-ANSWERSloss of circulating blood volume
cardiogenic shock - CORRECT-ANSWERSinability of heart to maintain cardiac
output to circulation
early manifestations of shock - CORRECT-ANSWERSanxiety, tachycardia,
pallor, light-headedness, syncope, sweating, oliguria
compensation for shock - CORRECT-ANSWERSSNS and adrenal medulla
stimulated- increase HR, renin increases, increased ADH, secretion of
glucocorticoids, acidosis stimulates increased respirations
ventilation - CORRECT-ANSWERSair always moves from high pressure area to
low pressure area
tidal volume - CORRECT-ANSWERSamount of air entering lungs with each
normal breath
residual volume - CORRECT-ANSWERSamount of air remaining in the lungs
after forced expiration
vital capacity - CORRECT-ANSWERSmaximal amount of air expired following
a maximal inspiration
