What side of the heart pumps blood through the lungs for oxygenation
The right side
What side of the heart pumps the oxygenated blood throughout the body
The left side
Part of the heart that receives non oxygenated blood from the body
Right atrium
Part of the heart that pumps blood through the pulmonary circulation
Right ventricle
Which part of the heart receives oxygenated blood from pulmonary circulation
Left atrium
Which part of the heart pumps oxygenated blood through the blood
Left ventricle
Which heart valve prevent backflow of blood from ventricles into atria during contraction
Tricuspid and mitral valve
Which heart valves prevent blood flow from aorta and pulmonary arteries during ventricular relaxation
Aortic and pulmonary valves
Pacemaker of the heart, source of the rhythmic electrical impulses.
Sinoatrial node
Delays impulse from the SA node to allow blood into the ventricles
Atrioventricular node
Conducts impulses to ventricles via the left and right bundle branches. Further branching into purkinje fibers
Atrioventricular bundle
