Blood vessels to the lower limb Flashcards
arteries vs veins
arteries have branches
veins have tributaries- small form into large
artiers- smaller lumen/ thick muscular wall/ blood away from the heart
veins- thin walls larger lumen smooth muscle
blood back to heart
aortic branches
aortic arch
decending aorta/ thoracic aorta= inferior into
abdomin aorta
at top of pelvis divdes into common iliac artery
common iliac artery
divides in pelvis into external and internal iliac artery
external iliac artery
under the inguinal ligament and becomes the femoral artery
internal iliac artery
branch- obturator supplying the medial thigh
femoral artery
deep femoral artery branch to posterior thigh
anterior thigh enters adductor canal- allows to transport to posterior leg
opens in popliteal fossa
popliteal artery
femoral artery becomes popliteal artery down posteior leg becomes posterior tibial artery
posterior tibial artery
supply the lateral leg via fibular artery
into foot splits to medial and lateral plantar
anterior tibial artery
supplys the dorsalais petrus for the foot
deep veins
contain valves
drain artery supply
thin wall see valves
vena commitaines
superfical valves
don’t match with paired artery
communicate with deep vains
not as many vains
fascia and skin drains
dorsal arch- drain each toe
short saphenous- popliteal region and lateral foot drain to popliteal vein
long saphenous- drain into femoral vein= medial aspect of lower limb
tributtaries of inferior vena carva
femoral vein under inguinal ligament
external iliac vein
internal iliac vein
common iliac vein
form inferior vena carva to the right side of the heart
lympathtic veins
lymphnode= filter
small- increase size
superfical- follow long/ short saphenous- more lymph nodes then deep
deep- follow paried arteries/ veins
