R ventricle > pulmonary trunk > pulmonary arteries > R and L lungs > pulmonary veins > L atrium

all systemic circulation arteries derive directly or indirectly from the aorta

1. ascending aorta > coronary arteries > heart muscle

2. aortic arch > brachiocephalic artery > common carotid and subclavian

3. descending aorta > thoracic (between aortic arch and diaphragm) and abdominal (between diaphragmn and two common iliac arteries)

upper limb

lower limb

head and trunk

ALL FROM AORTA

brachiocephalic (small, first branch from the aortic arch) > common carotid + subclavian artery

subclavian > vertebral

1. internal carotid > anterior/middle/posterior cerebral > 80% of the cerebrum

2. vertebral artery > basilar artery

cerebral arterial circle/circle of willis: provides alternative route for blood to reach the brain

-anastomosis between basilar and internal carotid at base of brain

anterior/posterior communicating, anterior/posterior cerebral, internal carotid

cerebellar artery

subclavian artery > axillary artery > branchial artery > radial and ulnar

1. celiac trunk

2. superior mesenteric

3. L/R suprarenal > adrenal glands

4. L/R renal > kidneys

5. L/R gonadal > ovaries or testes

6. lumbar > back and abdominal wall

7. inferior mesenteric

1. splenic artery > spleen, pancreas, STOMACH

2. left gastric artery > STOMACH

3. common hepatic artery > STOMACH, liver, gall bladder, SMALL INTESTINE

external iliac > femoral (thigh) > popliteal (knee) > anterior tibial (anterior leg) + posterior tibial (posterior leg)

anterior tibial > dorsalis pedis (foot) > digital arteries (toes)

posterior tibial > lateral and medial plantar arteries (foot) > digital arteries (toes)

posterior tibial > fibular (lateral leg and foot)

cardiac veins (walls of heart to the coronary sinuses)

superior vena cava (head, neck, thorax, upper limb)

inferior vena cava (abdomen, pelvis, lower limb)

superficial/deep veins, sinuses (heart and cranial cavity)

upper limb, lower limb, head and trunk veins

external jugular

internal jugular + subclavian > R brachiocephalic > superior vena cava

transverse, sigmoid, superior/inferior sagittal sinuses (spaces within dura mater) > internal carotid artery

ophthalmic vein: connects sinuses with the facial vein

superficial: cephalic vein and basilic vein > connected by median cubital

deep: brachial vein

hepatic portal vein made from:

1. splenic (spleen and pancreas) < inferior mesenteric (descending and sigmoid colon, rectum)

2. superior mesenteric (small intestine, cecum, ascending and transverse colon)

(3. gastric vein (stomach))

hepatic portal vein > liver > hepatic vein > inferior vena cava

superficial: great saphenous (largest vein in the body), small saphenous

deep: femoral, popliteal, anterior/posterior tibial, fibular veins

-localized dilation of a blood vessel

-commonly in arteries of brain or the aorta

-can be caused by trauma

-aneurysm to the aorta is fatal

-sudden interruption of blood to a region of the brain

-complication of hypertension
