Practical review

function of pulmonary arteries?

carries blood from the right ventricle to the lungs

location of pulmonary arteries?

originates from the right ventricle and leads to the lungs

function of aorta?

carries oxygen from the heart to the rest of the body

location of aorta?

the arch right above the heart that branches to the left and right coronary arteries

function of right and left coronary arteries?

supplying the heart muscle with necessary nutrients and oxygen

location of brachiocephalic artery (or inominate)?

the first branch of the aorta

function of brachiocephalic artery (or inominate)?

location of abdominal aorta?

passesthe diaphragm

location of celiac artery?

branches off from the left side of the aorta (unpaired artery)

function of celiac artery?

supplies blood to the organs of the upper abdominal

what are the three branches of the celiac artery?

pyloric (to the lesser curvature of the stomach and pylorus), anterior pancreatoduodenal (to the duodenum and pancreas), right gastroepiploic (to the greater omentum and greater curvature of the stomach)

location of left gastric artery?

along the lesser curvature of the stomach

function of splenic artery?

gives off branches to the pancreas, stomach, and spleen

what are the branches of the superior mesenteric artery?

posterior pancreaticoduodenal, middle colic, ileocolic, intestinal

function of superior mesenteric artery?

supplies the small intestine and parts of the large intestine

posterior pancreaticoduodenal artery

branches to the caudal portions of the pancreas and the duodenum

middle colic artery

branches to the ascending colon

ileocolic artery

branches to the cecum and ilium

what are the branches of the inferior mesenteric artery?

left colic and superior hemorrhoidal

left colic artery

branches to the descending colon

superior hemorrhoidal artery

branches to the rectum

what are the branches of the abdominal aorta in the caudal region?

adrenolumbar, renal, genital (internal spermatic or ovarian) artery

adrenolumbar

paired vessels to the adreno glands and lumbar body wall

renal

paired arteries to kidneys

genitals in male vs female

in males: paired arteries to the testes, in female: they supply the ovaries and uterus

what are the branches from the aorta that supply the body wall?

lumbar, iliolumbar, external iliac, deep femoral, femoral, and saphenous artery

lumbar artery

several paired arteries supplying the body wall

iliolumbar artery

paired vessels to the body wall

external iliac artery

branches of the abdominal aorta that pass to the hind limbs

femoral artery

continuation of the external iliac in the thigh

saphenous artery

continuation of the femoral artery past the thigh

what are the branches of saphenous artery?

superior articular, popliteal, anterior tibial, and posterior tibial artery

superior articular artery

branches to the knee

popliteal artery

continuation of femoral artery and divides into the anterior tibial and posterior tibial

anterior tibial artery

branches through the leg into the foot

what are the branches of deep femoral artery?

inferior epigastric, vesicular, and external spermatic artery

vesicular artery

to the bladder

external spermatic artery

to the spermatic cord and testes
