identify different veins and arteries

what are the 3 arteries that branch off the aorta?

• brachiocephalic

• left subclavian

• left common carotid

Identify the left and right common carotid artery and external and internal jugular vein in the picture

what two things branch off the common carotid arteries and what are their functions?

external carotid artery

• used to deliver blood to the head

internal carotid artery

• delivers blood to the cerebrum

what is the circle of willis?

loop of blood vessels that supply the brain

what are the TWO MAIN arteries that play an important role in supplying the circle of willis?

vertebral and internal carotid arteries

identify in the picture:

external and internal jugular vein

right and left subclavian vein

right and left brachiocephalic vein

right auxiliary artery and right axillary vein

what does the external jugular vein do?

collect blood from the superficial structures of the head

what does the internal jugular vein do?

collects MOST of the blood from the brain

what is the flow of blood from the jugular veins?

internal and external jugular vein—>subclavian vein—>brachiocephalic vein—>SVC

What are the 4 things that branch off the abdominal aorta, and what do they supply?

• inferior phrenic artery (supplies the diaphragm)

• celiac trunk (supplies the abdominal organs spllen, stomach, pancreas)

• superior mesenteric artery (supplies the intestines)

• renal artery (supplies the kidneys)

identify the:

inferior phrenic artery

celiac artery

superior mesenteric artery

renal artery

what do the internal and external illiac arteries supply? iliac

internal: supplies the pelvic region

external: gives rise to deep femoral arteries to supply the legs

identify the:

internal iliac artery and vein

external iliac artery and vein

deep femoral and femoral artery

anterior and posterior artery

great saphenous artery

common iliac vein drains:

the lower limbs

renal vein drains:

the kidneys

hepatic vein drains the:

liver

what is the hepatic portal system?

abdominal organs dump their deoxygenated blood into a vessel call the hepatic portal vein which serves as a port to the liver since the liver has a vessel that connects right to the IVC

Identify the:

hepatic portal vein

superior mesenteric vein

inferior mesenteric vein

IVC

splenic vein
