A&P Ch.18 Anatomy of the Blood Vessels

pulmonary circulation
..., circulation of blood between the heart and the lungs
systemic circulation
..., circulation that supplies blood to all the body except to the lungs
..., blood vessels that carry blood away from the heart
..., small vessels that receive blood from the arteries
..., the smallest blood vessels which connect the smallest arteries with the smallest veins. Nourishment and fluid noramlly trapped in thick walled arteries and veins can easily pass through the delicate walls of the capillaries
..., blood vessels that carry blood back to the heart
..., smallest veins
tunica intima
..., the innermost layer of a blood vessel, an endothelium
tunica media
..., middle layer of artery; made up of smooth muscle fibers and thick layer of elastic connective tissue
tunica adventitia
..., outer layer of blood vessel; fibrous connective tissue;
conductance vessels
primary function of the large arteries is to conduct blood from the heart to the arterioles, the large arteries are called this
resistance vessels
..., Arterioles, which can selectively constrict or relax to control the resistance to outflow of blood into the capillaries.
exchange vessels
another name for capillaries, since the primary function of capillaries is the exchange of substances between the blood and interstitial fluid
capacitance vessels
Because the veins store blood. Capacitance refers to storage. 70% of total blood volume found on venous side or circulation.
..., The largest artery in the body; it conducts freshly oxygenated blood from the heart to the tissues.
ascending aorta
The ascending part of the aorta as it emerges from the left ventricle; right and left coronary arteries branch from here.
arch of the aorta
..., The most superior portion of the aorta, Arch where the Ascending Aorta and Descending Aorta meet.
descending aorta
..., the descending part of the aorta that branches into the thoracic and abdominal aortae
thoracic aorta
..., a branch of the descending aorta
abdominal aorta
..., a branch of the descending aorta
brachiocephalic artery
..., a major artery, arising from the arch of the aorta, that supplies blood to the right arm and the head, right neck and shoulder.
left and right subclavian arteries
supply blood to the shoulders and upper arms
intercostal arteries
..., arteries that carry blood to the intercostal muscles
celiac trunk
..., an artery that originates from the abdominal aorta just below the diaphragm and branches into the left gastric artery and the common hepatic artery and the splenic artery
gastric artery
..., arteries that supplies the walls of the stomach
splenic artery
..., an artery that originates from the celiac trunk and supplies blood to the spleen
superior mesenteric artery
..., originates from the upper part of the aorta that supplies the small intestines and the cecum and the colon
inferior mesenteric artery
..., arises near the lower end of the aorta and supplies the large intestine
renal arteries
..., Arteries that supply blood to the kidneys
right and left common iliac arteries
..., Supply the pelvic organs, thighs, and lower extremities.
major arteries of the thigh and leg
external iliac arteries, femoral, popliteal, anterior, and posterior tibial arteries
dorsalis pedis artery
..., artery supplying the foot, lateral to the large tendon of the big toe
superficial veins
..., located near the body surface
deep veins
..., located within the tissues and away from the body surface
vena cava
..., either of two large veins that return oxygen-depleted blood to the right atrium of the heart
superior vena cava (SVC)
..., veins draining blood from the head, shoulders, and upper extremities
inferior vena cava (IVC)
..., conveys blood from the lower portion of the body (legs and torso) to the right atrium
axiallary vein
drains into subvlavian vein
cephalic vein
..., a large vein of the arm that empties into the axillary vein
basilic vein
..., a vein that drains the back of the hand and forearm and empties into the axillary vein
median cubital vein
..., The major vein of the antecubital fossa most commonly used for venipuncture (middle)
external jugular veins
..., Drain blood from the face, scalp, and neck. They empty into the subclavian veins
internal jugular veins
..., blood drain from brains
brachiocephalic veins
..., formed when the subclavian and internal jugular veins join
azygos vein
single vein that drains the thorax and empties directly into the subclavian veins.
tibial veins & peroneal veins
Drain the calf and foot region
great saphenous veins
..., Longest veins in the body
renal veins
..., The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava.
..., any disorder or disease of the brain
carotid arteries
..., the major arteries that carry blood upward to the head
right common carotid artery
...arises from the brachiocephalic artery
left common carotid artery
arises directly from the aortic arch
external carotid arteries
..., supply blood to the face, scalp, and neck.
internal carotid arteries
..., supply blood to portions of the brain.
vertebral arteries
..., branch from the subclavian arteries. They travel superiorly through the foramen magnum where they join to form the basilary artery.
..., a natural or surgical joining of parts or branches of tubular structures so as to make or become continuous
circle of Willis
..., A structure at the base of the brain that is formed by the joining of the internal carotid and basilar arteries
portal vein
large vein that carries blood from the organs of digestion to the liver. superior mesenteric vein & splenic vein combine to form.
superior mesenteric vein
..., the vein that carries blood from the small and first part of the large intestines
splenic vein
..., drains spleen, stomach, pancreas, and inferior mesenteric vein which drains the last part of the large intestine
inferior mesenteric vein
drains the last part of the large intestine
hepatic artery
..., arteries that supply the liver with oxygen rich blood and is a branch of the celiac trunk.
hepatic vein
..., a vein that drains the liver. EX. empties into the vena cava
splanchnic circulation
supplies blood to the stomach, spleen, pancreas, intestines and liver
..., belly button
umbilical cord
..., membranous duct connecting the fetus with the placenta
..., the vascular structure in the uterus of most mammals providing oxygen and nutrients for and transferring wastes from the developing fetus
umbilical vein
..., A vein in the umbilical cord; returns nutrient blood from the placenta to the fetus.

..., carry blood from the fetus to the placenta
ductus venosus
