arteries
large blood vessels that carry blood away from the heart
veins
capacitance vessels
pulmonary circulation
the path of the blood from the right ventricle of the heart to the lungs and back to the left atrium
capillaries
these tiny blood vessels are composed of a single layer of epithelium and therefore function as exchange vessels
veins
blood vessels that carry blood back to the heart
systemic circulation
the path of blood from the left ventricle of the heart to the body cells and back to the right atrium
arterioles
small arteries composed primarily of smooth muscle
capillaries
vessels that connect the arterioles with the venules
venules
small veins that drain the capillaries and converge to form large veins
veins
large vessels that contain valves
arterioles
resistance vessels
capillaries
the most numerous of the blood vessels
basilar artery
the vertebral arteries pass upward from the subclavian arteries toward the back of the neck; they extend upward into the cranium and join to form this artery
hepatic artery
a branch of the celiac trunk that supplies the liver
aorta
largest artery in the body; arises from the left ventricle of the heart
renal artery
artery that supplies the kidney
mesenteric arteries
these arteries are branches of the abdominal aorta; they supply blood to most of the small intestine and part of the large intestine
circle of Willis
an arrangement of arterial blood vessels found at the base of the brain
dorsalis pedis artery
an extension of the anterior tibial artery that supplies the foot
common iliac artery
the distal end of the abdominal aorta splits into this
celiac trunk
short artery that divides into the gastric artery, splenic artery, and hepatic artery
aorta
large artery that is classified as ascending, arch, and descending
aorta
large artery that is classified as thoracic and abdominal
coronary arteries
branches of the ascending aorta that supply the myocardium of the heart
internal carotid arteries
arteries that ascend on the anteriolateral aspect of the neck; supply the circle of Willis
left subclavian artery
branch of the aortic arch that supplies the shoulder and upper arm
internal carotid artery
name that means heavy sleep or stupor
great saphenous vein
located in the lower extremity; the longest vein in the body
femoral vein
large deep vein in the thigh that enters the pelvis as the external iliac vein
inferior vena cava
the common iliac vein continues as this vein
superior vena cava
this large vein drains the head, shoulders, and upper extremities and empties the blood into the right atrium
portal vein
formed from the union of the superior mesenteric vein and the splenic vein
jugular vein
vein that drains the head
inferior vena cava
large vein that returns blood to the right atrium from all the regions below the diaphragm
renal vein
drains blood from the kidney and empties it into the inferior vena cava
portal vein
large vein that carries blood from the digestive organs to the liver
hepatic vein
drains the liver and empties blood into the vena cava
subclavian vein
receives blood from the axillary vein and the external jugular vein
great saphenous vein
long superficial vein often "borrowed" for cardiac bypass surgery
median cubital vein
vein that joins the cephalic and basilic veins
median cubital vein
arm vein that is commonly used to withdraw a sample of blood
umbilical cord
structure that carries three blood vessels (two arteries and one vein); connects the mother with the fetus
foramen ovale
hole in the interatrial septum that allows fetal blood to shunt from the right atrium to the left atrium
placenta
place for maternal-fetal exchange of nutrients, gases, and waste
ductus venosus
structure that connects the umbilical vein with the fetal inferior vena cava; shunts blood past the fetal liver
ductus arteriosus
short tube that connects the fetal pulmonary artery with the aorta
placenta
structure that serves as lungs for the fetus
ductus arteriosus
failure of this opening to close after birth creates a left-to-right shunt between the aorta and the pulmonary artery
foramen ovale
failure of this opening to close after birth creates a left-to-right shunt between the atria
bright red
oxygenated blood is what color
veins
about 70% of all blood is located in these
arterioles
these have a lot of smooth muscle that allow them to contract and relax, thereby affecting blood vessel diameter
internal carotid arteries and vertebral arteries
supply oxygenated blood to the arteries of the brain (2)
the fetal lungs
the purpose of the ductus arteriosus is to bypass what
foramen ovale
this shunts blood from the right heart to the left heart in the fetus
jugulars
carry oxygenated blood from the brain
cognitive
atherosclerosis of a carotid artery causes impairment of what function
right-sided heart failure
this is most likely to cause JVD
portal vein
this carries blood that is rich in digestive end products to the liver
portal vein
superior mesenteric vein and splenic vein merge to for this
elevated portal vein pressure
ascites, portal hypertension, and esophageal varices are conditions caused by
subclavian veins
these empty blood into the brachiocephalic veins
basilar artery
delivers blood to the circle of Willis
