EKG
Which node is the pacemaker of the heart and capable of starting the electrical impulse that makes the atria contracts
SA node
main artery in the heart
Aorta
These valves stop the backflow of blood into the atria
Tricupsid, and Bicupsid valves
From the right ventricle, deoxygenated blood enters the..
tricupsid valve
sound that occurs during ventricular systole
LUBB
carries electrical signal down to the ventricles and delays signal
AV node
The Superior vena cava
structure that seperates the ventricals
from the pulmonary trunk, the deoxygenated blood enters the..
pulmonary arteries
An irregular heart sound
Murmur
stimulates contraction of the ventricles
Purjenke Fibers
structure that connects veinules and arterioles
Capilleries
This valve prevents backflow in the veins
Venous valves
before entering the left ventricle, oxygenated blood goes through the..
bicupsid valve
An increase in blood volume could be caused by
an increase in blood volume, heart rate, stroke volume, blood viscosity, periphial
represents ventricular depolarization
QRS complex
structure that deliveries oxygenated blood to the heart
Pulmanary veins
Capillaries
All deoxygenated blood enters through
the vena cava
this structure is used to reduce friction
Serous fluid
represents ventricular repolarization
T-wave
The valve that is directly before the Aorta is..
The aortic semi lunar valve
This structure pulls the A-V valves to open and close them
Cordae Tendenae
before entering the pulmonary trunk, blood travels through
The pulmonary semi lunar valve
This structure is the source of the heart's own blood supply
Coronary Arteries
