blood vessels Flashcards
blood normally flows into a capillary bed from
a metarteriole
plasma solutes enter the tissue fluid most easily from
fenestrated capillaries
a blood vessel adapted to withstand great fluctuations in blood pressure would be expected to have
an elastic tunica media
a circulatory pathway in which the blood flows through two capillary beds in series before it returns to the heart is called
a portal system
intestinal blood flows into the liver by way of
the hepatic portal vein
blood islands first form in the embryonic
yolk sac
All of the following blood vessels except the ___ are located in the upper limb. a. cephalic vein b. small saphenous vein c. brachial artery d. circumflex humeral arteries e. metacarpal arteries
small saphenous vein
the adult aortic arch develops from the embryonic
conus arteriosus
the adult aortic arch develops from the embryonic
left aortic arch IV
the two ___ veins unite like an upside- down Y to form the inferior vena cava
r/l iliac veins
filtration pores are characteristic of ___ capillaries
fenestrated
the capillaries of skeletal muscles are of the structural type called ___
continuous capillaries
the epithelium that lines the inside of a blood vessel is called ___
endothelium
the two ___ veins unite like an upside- down Y to form the inferior vena cava
common iliac
carotid and aortic bodies are called ___ because they respond to changes in blood chemistry
chemoreceptors
movement across the capillary endothelium by the uptake and release of fluid droplets is called ___
transcytosis
the two largest veins that empty into the right atrium are the ___ and ___
superior vena cava, inferior vena cava
the pressure sensors in the major arteries near the head are called ___
carotid sinuses
most of the blood supply to the brain comes from a ring of arterial anastomoses called the ___
cerebral arteriole circle
