Function of heart valves
keep blood from flowing back into the heart
Why is the heart muscle thicker on the left side than the right?
The left ventricle pumps blood to entire body, the right ventricle pumps blood to lungs
What would happen to the heart if excess fluid accumulated in pericardial sac?
Cardiac tamponade, compressed heart limits ability to pump blood
How do you treat excess fluid accumulation in pericardial sac?
insert syringe into pericardial cavity and drain excess fluid
intercalated discs
What is the function of intercalated discs?
Improves communication from muscle cell to muscle cell
recieves deoxygenated blood from the superior and inferior vena cava
right atrium
pumps deoxygenated blood to the lungs
right ventricle
receives oxygenated blood from the lungs
left atrium
pumps oxygenated blood to all parts of the body
left ventricle
right atrium and right ventricle make up
pulmonary circuit
left atrium and left ventricle make up
systemic circuit
irregular blood flow through heart
heart murmur
Four important areas used for listening to heart sounds
Aortic area, Pulmonic area, Tricuspid area, Mitral Area (Apex)
blood clot that forms in a vein deep in the body
deep vein thrombosis
