stomach, liver, pancreas, duodenum, spleen
Branches of the celiac?
left gastric, splenic, and common hepatic arteries
What organs does the SMA supply?

Renal arteries not only supply blood to kidneys but also to?
suprarenal glands and ureters
IMA supplies what organs?
transverse colon, descending colon, and part of the rectum
What aorta vessel arises 3-4cm above the bifurcation and can act as a collateral connection?
What region are the internal iliac arteries considered to be in?
course of the external iliac artery
medial side of psoas major muscle
external iliac becomes the common femoral artery once it passes where?
under the inguinal ligament
the superficial femoral artery passes through what canal?
adductor canal or hunters canal; passes through an opening in the tendon of the adductor hiatus
Another name for the deep femoral artery
A large branch that arises 5 cm from the inguinal ligament on the lateral side. Can act as a collateral connection.
Deep femoral artery
where does the SFA terminate and the popliteal artery begin?
adductor hiatus (hunters canal)
what leg artery gives off a number of genicular branches to supply muscles, knee joint, and skin?
at the interval of the tibia and fibula, the popliteal divides into what arteries?
anterior and posterior tibials
What leg arteries are referred to as the trifurcation?
ATA, PTA, and peroneals
First branch off the distal popliteal artery?
ATA becomes what artery?
Dorsalis pedis artery
Major branch of the DPA, penetrates the sole of the foot and unites with lateral plantar artery to complete the plantar arch.
deep plantar artery
Short segment between ATA branch and branches of PTA and peroneal arteries?
PT's extend obliquely down posterior/medial side of leg. What are the major branches?
Lateral and medial plantar arteries. Branch below medial malleolus to supply sole of foot.
Artery travels adjacent to the medial side of fibula to supply structures of the lateral side of leg/foot.
What arteries distribute blood to the digits?
plantar and dorsal metatarsals
What are arterioles considered?
Resistance vessels. Assist in regulating blood flow through contraction and relaxation.
Capillaries exchange what between tissue and blood?
nutrients and waste products
