blood vessels Flashcards
what do the geniculate arteries do?
- supply the knee joint
- anastomoses w/ popliteal artery at popliteal fossa
superficial veins of lower limb (3)
- ) dorsal venous arch
- ) small saphenous
- ) great saphenous
deep veins of lower limb (10)
- ) deep plantar venous arch
- ) posterior tibial veins
- ) fibular (peroneal) veins
- ) popliteal vein
- ) anterior tibial veins
- ) femoral vein
- ) deep femoral vein
- ) external iliac vein
- ) internal iliac vein
- ) common iliac vein
superficial veins of upper limb (5)
- ) dorsal venous network
- ) cephalic vein
- ) basilic vein
- ) median cubital vein
- ) median antebrachial vein
deep veins of upper limb (6)
- ) deep and superficial palmar arches
- ) radial veins
- ) ulnar veins
- ) brachial veins
- ) axillary vein
- ) subclavian vein
most common site of blood draw
-median cubital vein
hepatic portal system
- receives all of the blood draining from abdominal digestive tract, pancreas, gallbladder, and spleen
- “portal system” b/c blood passes through 2 capillary beds (intestine -> liver) before returning to heart
- liver gets first dibs at nutrients
- also allows liver to detoxify blood
sinusoids
-empty into hepatic veins, which drain liver and empty into IVC
3 branches of aorta
- ) brachiocephalic
- ) left common carotid
- ) left subclavian
branches of brachiocephalic
- ) right common carotid
2. ) right subclavian
cerebral arterial circle (circle of willis)
- surrounds pituitary gland and optic chiasm
- receives blood from internal carotid and basilar arteries
- most people lack some of its components
- crucial for understanding blood clots, aneurysms, stroke, and brain function
cerebral arterial circle components
- ) two posterior cerebral arteries
- ) two anterior cerebral arteries
- ) single anterior communicating artery
- ) two posterior communicating arteries
major veins of neck
- 3 on each side
1. ) internal jugular
2. ) external jugular
3. ) vertebral vein - responsible for draining head and neck
- all empty into subclavian vein
internal jugular vein
- receives most of blood into brain
- travels deep to sternocleidomastoid
- picks up blood from facial v, superficial temporal v, and superior thyroid v
external jugular vein
- travels superficial to sternocleidomastoid
- drains branches from salivary gland v, facial muscle v, scalp v
vertebral vein
- travels in transverse foramina
- does NOT come from brain
- drains cervical vertebrae, spinal cord, and small deep muscles of neck
celiac trunk
- median branch off the abdominal aorta, just below diaphragm
- supplies upper abdominal viscera
- numerous anastomoses and branches
- immediately gives rise to
1. ) common hepatic a.
2. ) left gastric a.
3. ) splenic a.
common hepatic artery
- arises from celiac trunk
- gives rise to- arteries supplying stomach/intestine
1. ) gastroduodenal a.
2. ) hepatic a. proper
hepatic artery proper
- ascends toward liver
- gives off R gastric artery
- then branches into R/L hepatic aa.
right hepatic artery
- gives rise to cystic artery to gallbladder
- then enters inferior part of liver adjacent to L hepatic artery
left gastric artery
- supplies stomach and lower esophagus
- arcs around lesser curvature (medial) of stomach and anastomoses w/ R gastric a.
anastomoses between superior and inferior mesenteric arteries
-many in order to ensure that blood keeps flowing to intestines even if one way is obstructed
superior mesenteric artery
- arises medially from abdominal aorta
- most significant intestinal blood supply
- serves most of small intestine and proximal half large intestine
vessels that supply the kidney
- renal arteries
- branch from abdominal aorta
