circulations Flashcards
what does the left common carotid supply?
left side of head and neck
what does the brachiocephalic trunk divide into?
right subclavian and right common carotid arteries
at what vertebral level does the common carotid bifurcate?
C4 — upper border or thyroid
what does the left common carotid divide into?
bifurcates in neck into left external and internal carotid arteries
what do the left external and internal arteries supply?
external — many structures in face and neck
internal — brain
what does the vertebral artery arise from and what does it supply?
- arises from subclavian artery
- supplies brain
what are located at bifurcation of common carotid?
carotid sinus and carotid bodies — monitor arterial stretch
identify A-D
A - right internal jugular
B - right external jugular
C - right subclavian vein
D - right brachiocephalic vein
what unites to from the right brachiocephalic vein?
right internal jugular and right subclavian
describe systemic circulation of upper limb
subclavian artery —> axillary artery —> brachial artery —> radial and ulna arteries
where do the left and right subclavian arteries arise from?
right - brachiocephalic trunk
left - aortic arch
where does the subclavian artery become to axillary artery?
lateral border of 1st rib
where does the axillary artery become the brachial artery?
inferior border of teres major
where does the brachial artery terminate?
in the cubital fossa by bifurcation into the radial and ulna arteries
where does the descending thoracic aorta arise and then pass through the aortic hiatus of the diaphragm?
- arises at T5
- passes through at T12
what does the descending thoracic aorta give rise to?
oesophageal, bronchial and posterior intercostal arteries
where does the renal vein lie in comparison to the renal artery?
renal vein lies anterior
where does the abdominal aorta bifurcate and what does it bifurcate into?
bifurcates into right common iliac and left common iliac at L4
where do the right and left renal arteries arise?
L1
where does the right renal artery pass in relation to the IVC to get to the right kidney?
passes posterior to the IVC
what unites to form the IVC and at what level?
left and right common iliac veins at L5
what crosses the abdominal aorta in order to drain into the IVC?
left renal vein
what do the left internal and external iliacs supply?
internal — organs, walls of pelvis and perineum
external — lower limb
where does the external iliac become the femoral artery?
as it passes under the inguinal ligament
where does the femoral artery become the popliteal artery?
in the popliteal fossa (back of knee)
what does the femoral artery pass through to get to the popliteal fossa?
adductor hiatus
name A-H
A - external iliac B - femoral artery C - deep femoral artery D - popliteal artery E - anterior tibial artery F - dorsal pedis G - posterior tibial artery H - peroneal artery
deep veins of lower limb
superficial veins of lower limb
what does the internal thoracic (mammary) artery arise from?
subclavian artery
where does the internal thoracic artery arise from, terminate and what does it give rise to?
- arises from the subclavian artery
- terminates at the level of the 6th rib by bifurcating into the musculophrenic and superior epigastric arteries
what does the hemiazygos vein drain? where does it drain into?
the lower 4 left IC spaces — drains into azygos vein
what does accessory hemiazygos vein drain?
commonly the 4th-8th IC spaces
label A -F
A = external iliac artery B = femoral artery C = profunda femoris artery D = popliteal artery E = anterior tibial artery F = peroneal artery
what does the small cardiac vein travel with?
marginal artery
what does the great cardiac vein travel with?
LAD
what does the middle cardiac vein travel with?
posterior descending
where is the venous angle? what drains into the left and right venous angles?
= at the junction of the internal jugular and subclavian veins
- right and left lymphatic ducts
the thoracic duct is on what side of the aorta?
RHS
what is the cysterna chyli?
the dilated sac that forms the start of the thoracic duct
where does the thoracic duct pass through the diaphragm?
T12
at what spinal level does the arch of the aorta terminate to become the descending aorta?
T4
what vessels originate from the aortic sinuses?
coronary arteries
what vessel supplies the anterior intercostal arteries?
internal thoracic artery
what does ST elevation is leads V1-V4 indicate?
anteroseptal stemi — LAD AFFECTED
