Chapter 5 - Blood Vessels

pulmonary artery

artery that carries blood away from the heart to the lungs. the pulmonary artery is the only artery that carries blood that as a low level of oxygen

axillary artery

artery that carries oxygenated blood to the axilla (armpit) area

popliteal artery

artery that carries oxygenated blood to the back of the knee and then branches into the tibial and peroneal arteries

tibial artery

artery that carries oxygenated blood to the font and back of the leg

iliac artery

artery that carries oxygenated blood to the hip and groin areas

radial artery

artery that carries oxygenated blood to the kidney

renal artery

artery that carries oxygenated blood to the kidney

ulnar artery

artery that carries oxygenated blood to the little finger side of the lower arm

peroneal artery

artery that carries oxygenated blood to the little toe side of the lower leg

carotid artery

artery that carries oxygenated blood to the neck, face, head, and bran. if these arteries are compressed, the lack of blood to the brain will cause a person to become unconscious.

subclavian artery

artery that carries oxygenated blood to the shoulder. it goes underneath the clavicle.

brachial artery

artery that carries oxygenated blood to the upper arm

coronary artery

artery that carries oxygenated blood to the upper leg

femoral artery

artery that carries oxygenated blood to the upper leg

vein

blood vessel that carries blood from the body back to the heart, this blood has a low oxygen level and a high carbon dioxide and waste products of cellular metabolism from he cells.

artery

blood vessel that carries oxygenated blood away from the heart to the body. Bright red blood has a high level of oxygen.

vasculature

blood vessels associated with a particular organ

great vessels

collective phrase for the aorta, the superior and inferior venae cavae, and the pulmonary trunk, pulmonary arteries, and pulmonary veins

vasoconstriction

constriction of smooth muscle in the wall of a blood vessel that causes the lumen to increase

blood vessels

large and small channels through which the blood circulates throughout the body these include arteries, arterioles, capillaries, venules, and veins that are also known as vascular structures. the lumen is the central opening inside a blood vessel through which the blood flows.

aorta

largest artery. it receives oxygenated blood from the left ventricle. it includes the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.

vasodilation

relaxation of smooth muscle in the wall of a blood vessel that causes the lumen to increase in size

capillary

smallest blood vessel in the body. a capillary network connects the arterioles to the venules. the exchange of oxygen and carbon dioxide takes place in the capillaries.

venule

smallest branch of a vein

arteriole

smallest branch of an artery

pulse

the bulging of the wall of an artery located near the surface as blood is pumped by the heart

venae cavae

the two major veins. the superior vena cava carries blood from the head, neck arms, and chest back to the right atrium of the hear. the inferior vena cava carries blood from he abdomen, pelvis, and legs back to the right atrium.

pulmonary vein

vein tat carries oxygenated blood from the lungs to the heart. the pulmonary vein is the only vein that carries blood that has a high level of oxygen

jugular vein

vein that carries blood from the head to the superior vena cava

portal vein

vein that carries blood from the intestines to the liver

saphenous vein

vein the carries blood from the leg to the groin
