Endothelial layer that lines the lumen of all vessels; reduces friction; innermost layer.
middle layer of artery; made up of smooth muscle fibers and thick layer of elastic connective tissue
aka adventitia. the outermost coating of the blood vessel composed of areolar and fibrous connective tissue. It is supportive and protective
internal elastic lamina
in between tunica media and tunica intima; has pores for nutrient diffusion
largest type of artery; contains many elastic fibers that allow it to stretch in response to each pulse; close to the heart
"Distributing" distal to elastic arteries, deliver blood to organs, thick tunica media
What's the difference between arteries and veins?
The difference is that arteries carry blood away from the heart and veins carry blood towards the heart.
Whats the structual difference between arteries and veins?
arteries are more muscular than veins, veins are often closer to the skin and contain valves to help keep blood flowing toward the heart, while arteries carry blood away from the heart.
the large trunk artery that carries blood from the left ventricle of the heart to branch arteries
Branches off the left ventricle; carries oxygen rich blood to parts of the body above the heart
the largest artery of the body; carries blood away from the heart down the midline of the body
blood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle
The first major branch off of the aorta and the major artery to the forelimbs and head.
common carotid arteries
o Right common carotid artery originates from the brachiocephalic trunk o Left common carotid artery originates from the arch of the aorta. Blood to head, face and neck.
left and right arteries found in the thoracic cavity, first branch to come off the aorta, supplies blood to the arms
internal carotid arteries
branch of common carotid artery and enters through the carotid canal; reached bases of brain through either side of sella turcica
superficial temporal arteries
artery that supplies blood to the muscles of the front, side, and top of the head
one of two main arteries to the brain (the other is ICA) is paired rising from the foramen magum and forms the basilar artery
