Blood Vessels Flashcards
Arteriole
Smallest branch of arteries; carries blood to capillaries
Blood Pressure (BP)
Measurement of pressure that is exerted by blood against walls of a blood vessel
Capillary Bed
Network of capillaries found in a given tissue or organ
Coronary Arteries
Group of three arteries that branch off aorta and carry blood to myocardium
Diastolic Pressure
Lower pressure within blood vessels during relaxation phase of heart beat
Lumen
Space, cavity, or channel within tube or tubular organ or structure in body
Pulse (P)
Expansion and contraction produced by blood as it moves through artery; pulse can be taken at several pulse points throughout body where artery is close to surface
Systolic Pressure
Maximum pressure within blood vessels during heart contraction
Venules
Smallest veins; receive deoxygenated blood leaving capillaries
