 artery | thin tunica externa |
| artery | thick tunica media |
| artery | narrow and regular tunica intima |
| vein | thick tunica externa |
| vein | thin tunica media |
| vein | irregular tunica intima |
| tunica intima | layer of endothelium |
| tunica media | layer of smooth muscle and elastic fibers |
| tunica externa | layer of collagen fibers |
| tunica intima | innermost tunic |
| tunica externa | most superficial tunic |
| tunica intima | thin tunic of capillaries |
| tunica media | specially thick in elastic arteries |
| tunica media | contains smooth muscle and elastin |
| tunica intima | has a smooth surface to decrease resistance to blood flow. |
| veins need valves to create pressure to pump the blood to the heart. valves assist in returning venus blood to the heart. | why are valves present in veins but not in arteries |
| muscular pump (milking action of skeletal muscle) and respiratoy pump (thoraxic cavity pressure) | name two events occurring within the body that aid in venous return |
| because arteries are closer to the pumping action of the heart, their walls must be strong enough to take the changes in pressure. | why are the walls of arteries proportionately thicker than those of the corresponding veins |
| brachiocephalic | the arterial system has one of these, the venous system has two. |
| coronary arteries | these arteries supply the myocardium |
| internal carotid and vertebral | two paired arteries serving the brain |
| great saphenous | longest vein in the lower limb |
| dorsalis pedis | artery on the dorsum of the foot checked after leg surgery |
| deep artery of the thigh | serves the posterior thigh |
| phrenic | supplies the diaphragm |
| brachial | formed by the union of the radial and ulnar veins |
| basilic and cephalic | two superficial veins of the arm |
| renal | artery serving the kidney |
| hepatic | veins draining the liver |
| inferior mesenteric | artery that supplies the distal half of the large intestine |
| internal iliac | drains the pelvic organs |
| femoral | what the external iliac artery becomes on entry into the thigh |
| brachial | major artery serving the arm |
| superior mesenteric | supplies most of the small intestine |
| common iliac | join to form the inferior vena cava |
| celiac trunk | an arterial trunk that has three major branches, whic run to the liver, spleen and stomach |
| external carotid | major artery serving the tissues external to the skull |
| anterior tibial, fibular and posterior tibial | three veins serving the leg |
| radial | artery generally used to take the pulse at the wrist |
