Delivers oxygen-poor blood to lungs
Low pressure |
Pulmonary circuit - after gas exchange occurs in lungs it delivers oxygen-rich blood to the systemic circuit
|
|
|
Delivers oxygen-rich blood to organs and tissues
High pressure |
Systemic Circuit - after organs and tissues use the oxygen rich blood it delivers the oxygen-poor blood to the pulmonary circuit

|
Tricuspid valve separates left/right atrium from ventricle?
|
Right atrium from the right ventricle
AKA right AV valve (atrioventricular) |
|
|
Mitral valve (Bicuspid valve) separates left/right atrium from ventricle?
and what forces it to close? |
Left ventricle from left atrium
AKA Bicuspid valve or left AV valve pressure greater in ventricle than in atrium forces it to close |
|
|
What is the difference between mitral valve stenosis (narrowing) and mitral valve regurgitation?
|
Stenosis is restriction (valve doesnt open completely)
Regurgitation = leaky valve/incompetent valve |
|
|
Right Semi-lunar valve aka Pulmonary valve
|
opens and closes b/c of pressure
separates right ventricle from pulmonary artery--always has pressure blood pressure = peak pressure/resting pressure |
|
|
Left Semi-lunar valve aka Aortic valve
|
separates left ventricle from aorta
bottom # = pressure in aorta at rest which is around 70 mmHg |
