Blood enters the left atrium through the pulmonary veins, and is pumped into the left ventricle through the mitral valve.
Mitral Valve
for the right atrium and right ventricle, the tricuspid valve separates the two. For the left, the mitral valve separates the two.
There is not a valve between the ventricles. The interventricular septum separates them.
triceps
Left Atrium and Left Ventricle. Its right heart sided counterpart is the tricuspid valve.
bicuspid Bicuspid
Blood enters the left atrium through the pulmonary veins, and is pumped into the left ventricle through the mitral valve.
There is no valve between the right and left ventricles. The interventricular septum separates the ventricles.
The bicuspid or mitral valve and the aortic valve are on the left side of the heart. The mitral valve separates the left atrium and left ventricle, and the aortic valve is between the left atrium and the aorta.
left ventricle and left atrium
The atrioventricular vales separate the atria from the ventricles. The left AV valve is also known as the mitral valve, and the right is the tricuspid valve.
right atrium - right ventricle = TRICUSPID VALVE; right ventricle - lungs = PULMONARY SEMILUNAR VALVE; lungs - left atrium = not really a valve, more a perforation in the left pericardium; left atrium - left ventricle = MITRAL VALVE; left ventricle - aorta = AORTIC SEMILUNAR VALVE.
