Cardiovascular Flashcards
3 layers of walls of blood vessels
tunica intima
tunica media
tunice externa/adventitia
tunica intima
endothelium and basement membrane
tunica media
layers of smooth muscle
tunica externa/adventitia
supporting outer matrix, anchors to neighbouring tissues
capillaries and sinusoids
exchange vessels
non fenestrated
no gaps between endothelial cells
diffusion occurs through the cells
fenestrated
small pores between the walls of neighbouring endothelial cells
greater fluid movement
sinusoids
larger irregular lumen
creates turbulence
gaps between neighbouring endothelial cells and basal laminar
gaps large enough for some cells to move between
the great vessels
great arteries
- brachiocephalic
- common carotid
- subclavian
following subclavian artery is
subclavian vein
travelling with common carotid
internal jugular vien
following subclavian artery is
subclavian vein
where internal jugular and subclavian meet
left and right branchiocephalic vein
joining of left and right brachiocephalic vein
superior vena cava
unpaired
vessels derived from gut tube
splanchnopleure within the abdomen
superior mesenteric - midgut organs
inferior mesenteric - hindgut organs
