how do arteries control their flow
no valves
flow controlled by systole and muscle contractions
how do veins control their flow
valves in upper/lower extremities
what are the 2 systems of veins and what do they correspond with
deep: always with artery of same name
superficial: no corresponding artery
where does blood supply to the arms come from
comes from the branches of the aortic arch (brachiocephalic/innominate, Left common carotid artery, left subclavian)
brachiocephalic trunk supplies arms by
divides into two branches
Right CCA: brain
Right subclavian artery: right arm
left subclavian artery supplies what
left arm

travel horizontally towards the shoulder
becomes axillary arteries at about the level of the humeral hear
axillary artery (extension of, originates, length/travels)
extension of the subclavian artery
originates at humeral head
a short segment that travels along axilla
brachial artery (come from what/where, continues to, divides into)
at upper/mid humerus axillary becomes brachial
continues to elbow
divided into ulnar/radial arteries
radial artery (travels)

radial and ulnar inferior to the elbow to form _____ veins
brachial

horizontal
____ vein will always drain into a ____ vein eventually
supeficial
deep
R/L brachiocephalic veins (formed by, join together)
formed by junction of the subclavian veins and jugular veins
R/L join to form the superior vena cava which drains into right atrium
cephalic vein (starts, ascends, drains)
starts at lateral aspect of hand
ascends along lateral arm
drain directly into the axillary vein
basilic vein (starts, ascends, medial to, joins)
starts at medial aspect of hand
ascends along posterior medial aspect of arm
medial to brachial veins
joins brachial vein to form axillary ein
median cubital vein (joins what/where)
joins cephalic/basilic veins at the elbow joint
aorta bifurcates where/into
L4
R/L common iliac artery
common iliac arteries (travels, pass how to CIVs, divide into)
travel inferiorly and slightly laterally in the pelvis
arteries pass laterally and anterior to CIVs
Divide into internal/external iliac arteries
internal iliac arteries (descend, supplies)
descend post/med into pelvis
supplies pelvic viscera/muscles
external iliac arteries travel
laterally towards leg
_____ becomes the CFA at the _______
external iliac
inguinal ligament
the CFA bifurcates to become the ______ (AKA ______) and the _____ (AKA _______)

posterior tibial artery
post/med
peroneal artery
post/lat
accompany the artery and share the same name
deep venous system
veins superficial to deep fascia
superficial venous system
connects deep and superficial venous systems
perforating veins
anterior tibial veins (ascends along, form)
ascend along anterior aspect of lower leg
unite to form anterior tibial trunk which drains the popliteal vein
posterior tibial veins (ascends along, drain into)
