|
vessels that transport blood
|
blood vessels
|
|
|
blood pumped from the heart to the lungs and back to the heart; R ventricle to lungs then back to the L atrium
|
pulmonary circulation
|
|
|
blood pumped from the heart to the body and back to the heart, L ventricle to R atrium
|
systemic circulation
|
|
|
largest artery in the body; carries oxygen rich blood from the L ventricle; most arteries branch from the heart
|
Aorta
|
|
|
large vessels with elastic walls; work under high pressure; carry blood away from the heart; stem from the aorta
|
arteries
|
|
|
resistance vessels; small arteries that slow blood flow; help control BP
|
arterioles
|
|
|
microscopic exchange vessels; one cell thick; connect arterioles and venules
|
capillaries
|
|
|
small veins
|
venules
|
|
|
vessels that carry blood to the heart; have valves; work under low pressure and are subject to clotting
|
veins
|
|
|
largest veins in the body; carry oxygen poor blood to the R atrium
|
vena cavae
|
|
|
brings oxygen poor blood to R atrium from above the heart
|
superior vena cava (SVC)
|
|
|
brings oxygen poor blood to the R atrium from below the heart
|
inferior vena cava (IVC)
|
|
|
contains approximately 65-70% of total blood volume; work under lower pressure; have valves
|
venous blood flow
|
|
|
located in the neck
|
Jugular
|
|
|
used for CABG procedures
|
Saphenous vein
|
|
|
supply the superficial areas of the neck, face, scalp
|
external carotids
|
|
|
supply the brain
|
internal carotids
|
|
|
branches from the internal carotids and basilar artery allowing a collateral route for blood
|
circle of willis
|
|
|
internal and external jugular to the subclavian veins to the SVC (superior vena cava)
|
venous drainage from the brain
|
|
|
the routing of blood by portal veins to the liver
|
hepatic portal circulation (splanchnic)
|
|
|
carry oxygen poor blood to the liver; also carry blood to SIPS
|
portal vein
|
|
|
SIPS
|
stomach, intestines, pancreas, spleen
|
|
|
carries oxygen poor blood to the IVC (inferior vena cava)
|
hepatic vein
|
|
|
brings oxygen rich blood to the liver
|
hepatic artery
|
|
|
blood circumventing the lungs
|
fetal circulation
|
|
|
the pressure exerted against the walls of the arteries by the pumping action of the heart; how hard the heart is working to pump blood
|
blood pressure
|
|
|
average BP
|
120/80
|
|
|
top number of BP; ventricles contracting
|
systolic
|
|
|
bottom number of BP; ventricle relaxing
|
diastolic
|
|
|
the difference between systolic and diastolic numbers
|
pulse pressure
|
|
|
average pulse pressure
|
40
|
|
|
consistently high BP
|
Hypertension (HTN)
|
|
|
the recoil of arterial walls due to the pressure of the heartbeat
|

|
normal pulse range
|
60-80 bpm
