To determine the right and left valves of the clam, put the valve in your hand with the nacre facing you and the beak pointing up. If the beak is toward the right, it is the left valve, and if it is toward the left, it is the right valve.

Compare the functions of the three types of blood vessels in the circulatory system?
the blood comes in the through the superior and inferior vena cava. it then passes through the right atrium and is pushed through by the bicuspid valves. it enters the right ventricles and exits the heart through the right semi lunar valves and the pulmonary arteries and into the lungs. it is then brought back in through the pulmonary veins and passes through the left atrium. it is pushed through by the bicuspid valves and into the left atrimu and exits through the left semi lunar valves and out through the aorta to the rest of the body.
In what other structures of the circulatory system are valves found?
You have the atrioventricular valves that are the valves separating each atrium from the ventricles. The right AV valve is the tricuspid valve, while the left AV valve is the bicuspid/mitral valve. There are also two valves that lead from the heart to the pulmonary and aortic arteries. These are the pulmonary and aortic valves. They are both semilunar valves because of their shape.
What is the vavle that stops blood from flowing back into the right atrium?
A atrio-ventricular valve is the structure that stops blood flowing backwards into the atria. There is one of these valves on both the left and right sides of the heart.
What are the structures of the circulatory system that keep blood flowing in one direction?
Valves in your heart keep out the backwash of "dirty" blood, therefore it only travels from right to left to be "cleaned" and oxidized by the lungs. Once oxidized, it returns to the rest of the body and thus, back into the heart. Repeat!
What separates the upper and lower chamber?
The AV valves separate the upper and lower chambers of the heart. The bicuspid valve is on the left, and the tricuspid on the right.
The heart valves are arranged with the?
valves in the heart are at the opening of the right and left auricle,poening of the right and left venticle and the closing of the right and left ventricle
What are the four valves?
left and right atriums left and right ventricles
What is a cuspid valve?
Cuspid valves are right and left atrioventricular (AV) valves.
Is there is mixing of blood from right to left side of heart normally?
No because the valves present between the right atria and left atria (interartrial valves ) and the valves present between the right ventricle and left ventricle (interventricular valve ) allow the unidirectional flow of blood only ;
Name all the valves of the heart?
The valves in the heart are:Between the right atrium and the right ventricle is the tricuspid valve.Between the left atrium and the left ventricle is the bicuspid valve.In the pulmonary artery and aorta are the semi lunar valves.
What are the 4 chambers and 4 values of the heart?
4 chambers are 1. right atria 2.right ventricle 3.left atria 4 left ventricle 4 values are 1.tricuspid valves in between the right atria and right ventricle 2.mitral valve or bicuspid valves in between the left atria and left ventricle 3.Aortic valves 4.pulmonary valve
Valves separating atria and ventricles are cal led what valves?
for the right atrium and right ventricle, the tricuspid valve separates the two. For the left, the mitral valve separates the two.
Do valves control the flow of blood from the artia to the ventricles?
No, it flows from the Right Atrium to the Right Ventricle then to the Left Atrium to the Left Ventricle. Hope this helps!
Trace the pathway of blood through the heart Include major veins arteries chambers and valves.?
You're better off with a diagram, but I'll try... Blood enters from the right through the vena cava into the right atrium. The tricuspid valves let it into the right ventricle. From there the semilunar valves let it into the pulmonary artery. From there it goes to the lungs, and returns, oxygenated, in the pulmonary vein, entering on the far left. It goes into the left atrium and then is let into the left ventricle by the bicuspid valves. From there it goes through the semilunar valves to the aorta and from there to the rest of the body.

Where are the two valves in the heart?
There are actually four valves in the human heart. The heart has four chambers. The upper two are the right and left atria. The lower two are the right and left ventricles. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction. -The tricuspid valve is between the right atrium and right ventricle. -The pulmonary or pulmonic valve is between the right ventricle and the pulmonary artery. -The mitral valve is between the left atrium and left ventricle. -The aortic valve is between the left ventricle and the aorta. Each valve has a set of flaps (also called leaflets or cusps). When working properly, the heart valves open and close fully.
Valves separating atria and ventricles are?
The general term would be atrioventricular valves or AV valves. There are two of these valves: the one on the right side is known as the tricuspid valve and the one on the left is known as the mitral valve.
