what’s the first major branch of the abdominal aorta?

celiac trunk (celiac artery)

what does a celiac trunk split into?

The splenic artery, the left gastric artery, and the common hepatic artery

splenic artery

takes blood to the spleen, pancreas, and part of the stomach

left gastric artery

take blood to the stomach and esophagus

common hepatic artery

take blood to the liver

what is inferior to the celiac trunk?

superior mesenteric artery

where does the superior mesenteric artery take blood too?*

continues through the mesentary until it reaches the small intestine and proximal portions of the larger intestine, including the cecum, the ascending colon, and part of the transverse colon

where are the major branches of the superior mesenteric artery?

Intestinal arteries, ileocolic arteries, and the right and middle colic arteries

where do the suprarenal arteries take blood to?

the adrenal glands

what is inferior to the suprarenal arteries?

left and right renal arteries; which take blood to the kidneys

what’s inferior to the renal arteries?

gonadal arteries; descend to either the testes or the ovaries

what’s the next major vessel to leave the aorta?

inferior mesenteric artery

where does the inferior mesenteric artery take blood?

Takes blood to the lower portion of the large intestine, including part of the transverse colon, the descendent colon, and the rectum

how does the abdominal aorta terminate?

dividing into the two common iliac arteries, that take blood to the internal and external iliac arteries

where does the internal iliac artery take blood?*

takes blood to the pelvic region, including branches that take blood to the rectum, pelvic floor, external genitalia, groin, muscles, and hip muscles, as well as the uterus, ovary, and vagina in females

where do the external iliac artery exit into?

inguinal canal, continuing into the thigh as the femoral artery

what are the two branches of the femoral artery?

a superficial branch that feeds the thigh and a deeper branch, called the deep femoral artery, which takes blood to the muscles of the thigh, knee, and femur

what does the femoral artery turn into posterior to the knee?

popliteal artery; which divides into the posterior tibial artery in anterior tibial artery, which take blood to the knee and leg

what’s another branch of the popliteal artery?

fibular artery; which supplies the muscles on the lateral side of the leg

what do the tibial and fibular arteries do?

anastome and supply blood to the plantar arteries, the dorsalis pedis artery, and the digital arteries

where does cholesterol plaque (arteriosclerotic plaque) develop?

under the endothelial layer

what is arteriosclerosis?

hardening of the arteries and is caused by the development of cholesterol plaque
