supply arteries to the pancreas, small intestine, and most of large intestine
What organ does the superior mesenteric artery supply?
urinary bladder, internal and external walls of pelvis, external genatilia and medial side of thigh
What location does internal iliac artery supply?
ventral and lateral regions of the skin and deep muscles of the thigh
What location does the deep femoral artery supply?
skin and muscles of anterior portion of the leg
What location does the anterior tibial artery supply?
Brachiocephalic Trunk, left Common Carotid, left Subclavian
First, second and third branches off the aortic arch.
A branch of the subclavian artery that issues finer branches to the pericardium
Elastic arteries (conducting arteries)
--Large vessels (e.g., pulmonary trunk and aorta)
--Tunica media has many elastic fibers and few muscle cells
--Elasticity evens out pulse force
--transport large volumes of blood away from the heart.
Muscular arteries (distribution arteries)
--Are medium-sized (most arteries)
--Tunica media has many muscle cells
--Transport blood to the body's skeletal muscle and internal organs.
--Greater density of smooth muscle within the media than elastic arteries.
--Have little or no tunica externa
--Have thin or incomplete tunica media
--they control the blood flow between arteries and capillaries.
--is poorly defined and the media consists of scattered smooth muscle fibers that may not form a complete layer.
the smallest venules lack a media. However, in the largest venules you will find scattered smooth muscle cells
contain a thin media and the thickest layer is the adventitia which contains longitudinal bundles of elastic and collagen fibers
*Ex. superior and inferior venae cavae* all of the layers are thickest in large veins. Still a slender media which is surrounded by a thick adventitia, mix of elastic and collagenous fibers
left and right coronary arteries originate at the base of ascending aorta and branch off to the supply the heart with blood
What location does ascending aorta supply?
the diaphragm divides the descending aorta into a superior thoracic aorta and an inferior abdominal aorta
What location does descending aorta supply?
cervical spinal cord and posterior surface of the skull
What location is drained by the vertebral vein?
digital veins empty into the superficial and deep palmar veins of the hand
What location is drained by the palmar venous arches?
blood leaving capillaries in the sole of each foot collects into a network of plantar veins
What location is drained by plantar venous arch?
collects blood from the capillaries on the dorsal surface of the foot and digital veins of the toes
What location is drained by dorsal venous arch?
recevies blood from deep femoral vein, great saphenous vein, femoral circumflex vein
What location is drained by the femoral vein?
receives blood from the lower limbs, pelvis, and lower abdomen
What location is drained by the external iliac vein?
