arteries
carry blood away from the heart
capillaries
microscopic vessel through which exchanges take place between the blood and cells of the body
veins
blood vessels that carry blood back to the heart
what kind of arteries are elastic?
larger arteries
what kind of arteries are muscular?
smaller arteries
arterioles
small vessels that receive blood from the arteries
venules
small vessels that gather blood from the capillaries into the veins
venous sinuses
drains venous blood back into heart or other veins
anastomosis
surgical joining of two ducts, vessels, or bowel segments to allow flow from one to another
varicose veins
abnormally swollen, twisted veins with defective valves; most often seen in the legs
arterial supply, what does it do and where does it start?
supplies blood to the cells of the heart, begins at brachiocephalic trunk
superficial venous supply
drain superficial palmar venous arch
deep venous supply
drain palmar digital veins and deep palmar venous arch
abdominal aorta
continuation of the thoracic aorta that runs through the abdominal cavity
internal iliac artery
main artery of the pelvis
external iliac artery
supplies lower limbs
inguinal ligament
ligament extending from pubic bone to anterior superior iliac spine, forming lower border of abdomen
deep artery of the thigh
main artery that serves the thigh muscles
anterior tibial artery
supplies blood to the lower leg muscles and skin on the top of the foot and adjacent sides of the first and second toes
dorsal pedal artery
dorsal artery of the foot; continuation of the anterior tibial artery at the ankle
posterior tibial artery
artery supplying the foot, behind the medial ankle
medial plantar artery
arises form the bifurcation of the posterior tibial arteries; supplies blood to the medial plantar surfaces on the foot
fibular artery
supplies the lateral compartment of the leg
deep veins
responsible for returning blood during exercise
