The delivery system of dynamic structures that begins and ends at the heart |
blood vessels |
|
carry blood away from the heart |
arteries |
|
contact tissue cells and directly serve cellular needs |
capillaries |
|
the blood is oxygenated except for pulmonary circulation and umbilical vessels of a fetus |
arteries |
|
endothelium with sparse lamina |
capillaries |
|
carry blood towards the heart |
veins |
|
heart - large veins (capacitance vessels) -small veins (capacitance vessels)- postcapillary venule thoroughfare channel - capillaries |
venous system |
|
elastic arteries-(conducting vessels)-muscular arteries (distributing vessels) |
arterial system |
|
central blood containing space, which is surrounded by three distinct layers or tunics |
lumen |
|
the innermost tunic |
tunica intima |
|
it is in intimate contact with the blood in the human |
tunica intima |
|
simple squamous endothelium lines the lumen of all vessels, in vessels larger than 1mm of a subendothelial connective tissue basement membrane is present |
tunica intima |
|
smooth muscle and sheets of elastin, sympathetic vasometer nerve fibers control vasoconstriction and vasodialation of vessels |
tunica media |
|
reduction in lumen diameter as the smooth muscle contracts |
vasoconsetriction |
|
increase in lumen diameter as the smooth muscle contracts |
vasodialation |
|
collagen fibers protect and reinforce large vessels contain vasa vasorum to nourish the external layer |
tunica externa |
|
a system of tiny blood vessels that nourish the more external tissues of the blood vessel wall-its own blood supply |
vasa vasorum |
|
largest artery of the body |
aorta |
|
supplies the kidney |
renal artery |
|
supplies the duodenum and stomach |
common hepatic artery |
|
supplies the distal areas of the large intestine |
inferior mesenteric artery |
|
supplies pelvic structures |
aorta |
|
artery that does not anastomose |
renal artery |
|
gives rise to the right common carotid and right subclavian artery |
brachiocephalic trunk |
|
supplies the lower limbs |
external illiac artery |
|
major supply to the cerebral hemispheres |
internal carotid artery |
|
large unpaired branch of the abdominal aorta that supplies the liver, stomach, and spleen |
celiac trunk |
|
receives blood from all areas superior to the diaphragm, except the heart wall |
superior vena cava |
|
carries oxygen-poor blood to the lungs |
pulmonary trunk |
|
drains the scalp |
renal artery |
|
runs through the armpit area, giving off branches to the axillae, chest wall, and shoulder girdle |
axillary artery |
|
drains the upper extremities, deep vein |
subclavian vein |
|
artery usually palpated to take the blood pressure |
brachial artery |
|
major artery of the thigh |
femoral artery |
|
supplies the small intestine |
superior mesenteric artery |
|
carries oxygen rich blood from the lung |
pulmonary vein |
|
vessel commonly used as a coronly bypass vessel |
great saphenous vein |
|
site where resistance to blood flows is greatest |
arterioles |
|
site where exchanges of food and gasses are made |
capillaries |
|
site where blood pressure is lowest |
large veins |
|
site where the velocity of blood flow is fastest |
large arteries |
|
site where the velocity of blood flow is slowest |
capillaries |
|
site where the blood volume is greatest |
large veins |
|
site where the blood pressure is greatest |
large arteries |
|
site that is the major determinant of peripheral resistance |
arterioles |

a family of peptides called ___ are released by the endothelium and are among the most potent vasoconstrictors known |
endothelins |
|
arterial ___ provide alternate pathways for blood to get to an organ |
anastomoses |
|
the ___in the carotid sinuses and aortic arch detect increases in blood pressure |
