What is the meaning of valve of the heart?
It is the door/opening between the ventricles and atriums.
What is considered upper heart valves?
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
Do papillary muscles prevent the AV valves from prolapsing excessively into the atria when the ventricles contract?
Papillary muscles are connected to the chordae tendonae on the AV valves. During ventricular systole ( contraction of the ventricles) the papillary muscles contract preventing regurgitation of blood back into the atriums.
What are the upper chambers of the heart and their function?
right and left atrium. they collect and hold blood before sending them into the ventricles where they are pumped to all parts of the body.right and left atrium. they collect and hold blood before sending them into the ventricles where they are pumped away from the heart.right and left atrium. they collect and hold blood before sending them into the ventricles where they are pumped to all parts of the body.
What part of the heart acts like doors that control blood flow?
The four valves in the heart are: * the two semi-lunar valves - one at the stem of the aorta, the other is found at the trunk of the pulmonary artery. * The tricuspid valve is on the right-hand side of the heart. * The bicuspid valve is on the left side of the heart.
How are atriums and ventricles similar?
only they know
What is between atriums and ventricles?
The atrioventricular valves.
What is a atria and ventricles?
atriums and ventricles are apart of the four parts of your heart ventricles are on the bottom and atrium's are on the top hope this helped =D
Does the cardiac muscle open and close?
some does like the atriums and the ventricles
What are the four valves?

What is the meaning of valve of the heart?

How does the heart perform it functions?
The atriums squeeze to push blood to the ventricles, and the ventricles push the blood to separate parts the body.
Number of chamber in the heart?
4 2 ventricles and 2 atriums.
What organ has two chambers called atriums and two chambers called ventricles?
Heart
What makes the valves between atriums open and close?
There are no valves between the atria. The valves between the atria and ventricles close when the ventricles contract.
How many chambers are there in a human heart?
4; the right and left ventricles and the right and left atriums.
What is found in the third ventricle?
In the heart of a mamal there are only two ventricles and two atriums (atria).
