-
arteries
-
blood vessels that carry oxygenated blood from the heart to the body
-
arterioles
-
arteries shrink to this smallest form and link with capillaries
-
atria
-
the top two heart chambers
-
atrioventricular (AV) node
-
a second node in the heart that creates a delay in the electrical impulse from the SA node to the bundle of His to allow time for ventricular filling
-
bundle of His
-
a bundle of conducting fibers that branch to each ventricle of the heart
-
capillaries
-
the point at which arteries and veins exchange blood supply
-
cardiovascular system
-
a system within the body that includes the heart, blood vessels, blood, lymph, lymphatic vessels, and glands that moves blood and lymph through the body
-
circulatory systems
-
interconnected blood vessels that flow through the body
-
electrocardiogram (ECG/EKG)
-
a recording of a heart’s electrical activity in which electrodes are placed on the chest to capture signals
-
hypoalbuminemia
-
a condition where the body does not produce enough albumin, a protein that keeps fluids in blood vessels
-
normal sinus rhythm (NSR)
-
the heart’s cardiac rhythm that originates from the sinus node
-
perfusion
-
the movement of blood, oxygen, and nutrients to tissues in the body
-
pulseless electrical activity (PEA)
-
electrical conduction throughout the heart without physical movement of the heart muscle
-
Purkinje fibers
-
terminal-conducting fibers in the ventricles
-
sinoatrial (SA) node
-
the pacemaker of the heart
-
telemetry
-
the measurement of a heart’s ECG through a portable device that automatically transmits to a monitor
-
veins
-
blood vessels that carry deoxygenated blood from the body to the heart
-
ventricles
-
the bottom chambers of the heart
-
venules
-
the smallest veins that link with capillaries
