vessel type : artery a) open, circular lumen b) thick media vessel type : vein a) somewhat collapsed lumen b) thinner media

innermost tunic has a smooth surface to decrease resistance to blood flow thin tunic of capillaries

contains smooth muscle and elastin

most superficial tunic

The high blood pressure in arteries propels the blood through them. The blood pressure in veins is low and often the blood is flowing against gravity. Valves prevent back flow.

1) skeletal muscle "milking action" 2) changes in thoracic cavity pressure during breathing

Arteries must withstand high pressure and pressure fluctuations. Veins are low pressure vessels.

the arterial system has one of these; the venous system has two

these arteries supply the myocardium

two paired arteries serving the brain

longest vein in the lower limb

artery on the dorsum of the foot

main artery that serves the thigh muscles

supplies the diaphram

formed by the union of the radial and ulnar veins

two superficial veins of the arm

artery serving the kidney

veins draining the liver

artery that supplies the distal half of the large intestine

drains the pelvic organs

what the external iliac artery becomes on entry into the thigh

artery that branches into radial and ulnar arteries

supplies most of the small intestine

join to form the inferior vena cava

an arterial trunk that has three major branches, which run to the liver, spleen, and stomach

major artery serving the tissues external to the skull

four veins serving the leg

artery generally used to take the pulse at the wrist

Protection - it provides alternate pathways for blood to reach the brain tissue

1) internal carotid 2) cerebrum

Aorta ? subclavian artery ? vertebral artery ? basilar artery ? posterior cerebral artery ? occipital brain tissue.

Digital vein, L radial vein, L brachial vein, L axillary vein, L subclavian vein, L brachiocephalic vein, superior vena cava, R atrium, R ventricle, pulmonary trunk, pulmonary artery, lobar artery, pulmonary capillaries of the lung, lobar veins, pulmonary veins, L atrium, L ventricle, aortic arch, brachiocephalic artery, R subclavian artery, R axillary artery, R brachial artery, R radial artery, digital artery

Through mitral valve into left ventricle, aorta, common iliac artery, external iliac artery, femoral artery, posterior tibial artery, medial plantar artery, digital artery, capillary beds, digital vein, plantar arch, plantar vein, posterior tibial vein, femoral vein, external iliac vein, common iliac vein, inferior vena cava, right atrium, then through tricuspid valve

Inferior vena cava right atrium tricuspid valve right ventricle pulmonary semilunar valve pulmonary trunk right or left pulmonary artery lobar artery pulmonary capillary beds in lungs air sacs (alveoli) of lungs.

Alveolus alveolar/capillary walls* pulmonary vein left atrium bicuspid (mitral) valve left ventricle aortic semilunar valve aorta systemic arteries capillary beds of tissues* systemic veins superior or inferior vena cava right atrium

The pulmonary arteries carry oxygen-poor blood to the lungs. The pulmonary veins carry oxygen-rich blood from the lungs to the left atrium of the heart.

The pulmonary arteries are more like veins anatomically. - relatively thin walls, reflecting the fact that pulmonary circulation is a low pressure bed

placenta

blood drained from the digestive viscera

the blood is rich in nutrients. its phagocytes also cleanse the blood of debris.

Capillaries of small intestine ? superior mesenteric vein ? hepatic portal vein ? liver sinusoids ? hepatic vein ? inferior vena cava ? right atrium of heart
