∙ 13y agovalves in the heart are like doors.
there are 4 main chambers of the heart; the left and right atrium & the left and right ventricle.

∙ 12y agothere is the bicuspid valve which opens up to allow oxygenated blood into the heart after the oxygenated blood has entered the heart, i closes to prevent flowback of the blood, then the semi lunar valve opens up which allows the deoxygenated blooto exit, and once it has exited, it closes for the same reason which is to prevent flowback. so basically it is to prevent the flowback of blood

How is a pigs heart similar to human heart?
They are similar in size, anatomy, and function. They both have four chambers and four valves, which is why it is sometimes used for a heart transplant
What prevents back flow when the heart is relaxed?
Valves. There are four in the heart and the rest of the valves are dispersed throughout the body. They function as muscles around the blood vessel contract to move the blood.
What is considered upper heart valves?
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
Why are each section of the heart separated by valves?
The valves keep blood flowing in one direction. And there are even valves in the veins. The system is called a circulatory system and the system must keep going in a circle to function properly.
What is the function of the valves?
Valves prevent blood from going backward.Valves in general open to allow or close to prevent liquid flow. Heart valves opens to let blood into the heart then close to keep it there so that when the heart muscle contracts and squeezes the blood it is then forced out into the arteries of the body.
Do heart valves control the direction of blood flow?
Yes. That is 'the' function of the heart valves or for that matter valves.
What do the valves in arteries do?
Valves function to help keep blood flowing toward the heart. Arteries function to carry blood away from the heart.
Do the valves in the heart prevent the blood from flowing backwards?
That is so true! In fact it is the function of the heart valves.
What is the function of the valves which connect the two heart chambers?
Valves prevent the backflow of blood.
What is the function of valves in the heart and the veins?
I don't know what it is. I'm sorry :(
What is the function of the valves of your heart?
to keep the blood going one way
What is the function of valves int the heart and the veins?
The valves stop the blood flowing backwards through the circulatory system.
What are equiped with the chordae tendinea and papillary muscles?
The heart valves are attached to the chordae tendinae and papillary muscles which function to open the valves.
What is the function of bicuspic valves?
The bicuspid valve allows blood to pass from the heart to the aorta but then keeps it from flowing back into the heart.
