Heart valves are what allow your heart to act as a pump. There are 4 of them in your heart. A bicuspid (also known as mitral valve), which divides your left atrium (upper portion of the heart) from the left ventricle (lower/larger and more muscular portion). A tricuspid valve, on the right side of your heart divides the right atrium from the left ventricle in a similar manner as I explained for the left, the only difference (in regards to structure) is that this valve has the flaps on it (hence "TRIcuspid) as opposed to two (BIcuspid). Lastly, there is an aortic valve on the left side, and a pulmonic valve on the right. The left side of the heart receives oxygenated blood into the left atrium via the pulmonary veins. The left atrium contracts, sending the blood through the mitral valve into the left ventricle. Immediately following this, the left ventricle contracts and sends the blood out through the aortic valve, into the aorta and out to the rest of your body.
The right side of the heart receives used up / deoxygenated blood from the superior and inferior vena cava (SVC and IVC), into the right atrium. The right atrium then contracts and pushed the blood through the tricuspid into the right ventricle. The right ventricle then contracts and pushes the blood through the pulmonic valve into the pulmonic artery out to the lungs to pick up more oxygen! Although I separated the processes of left and right contraction, they actually occur simultaneously.
So as I indicated above, there are four chambers. In order for your heart to effectively pump blood it must open and close valves at different times during contraction so as to generate enough pressure to push blood through the vessels of your body. If there were not valves, there would be no pressure, and consequently, there would be no circulation.

What is the purpose of the valves which connect the heart chambers?
Valves are present in heart are used to prevent backflow of blood in heart due to reduce in pressure in atrium.
What is considered upper heart valves?
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
What is the purpose of heart valaves?
The reason we have valves in our heart is to direct the flow of blood in one direction. This ensures that it is able to circulate through the body.
Where can valves be found other than the heart?
Valves can be found in the heart aswell as the veins
List the valves of the heart and describe how they operate.?

What is the purpose of the valves which connect the heart chambers?
Valves are present in heart are used to prevent backflow of blood in heart due to reduce in pressure in atrium.
Where else in the circulatory system are valves found?
Valves can be found in the heart. They sit between the Atria and the Ventricles and help aid cardiovascular activity.
What is the purpose of a closed heart valve?
A closed heart valve is meant to prevent backflow of blood in the heart. There are valves that separate the atria and ventricles, and valves that separate the ventricles and arteries.
What is the purpose of the valves in the heart and the veins?
your semi lunar valves stop slop from entering your left aorta and your lunar valves stop crud from entering your right ventricle. this is the purpose of your valves. but this is different in dogs as your septum helps fight against testicular torsion.

What causes the beating of you heart?
Specialized heart muscle cells in the sino-atrial (SA) node which is located in the right atrium. These serve as the heart's "pace maker".
What is the use of valves in the heart.?
The use of the valves in the heart is to have blood flow regularly through the heart. The valves pump blood out of the heart into the body.
What is considered upper heart valves?
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
What purpose does n artificial pacemaker serve and how does it function?
It keeps your heart at a steady pace.
What do the chordate tendonae do?
Chordae tendineae: Thread-like bands of fibrous tissue which attach on one end to the edges of the tricuspid and mitral valves of the heart and on the other end to the papillary muscles, small muscles within the heart that serve to anchor the valves.
Do heart valves control the direction of blood flow?
Yes. That is 'the' function of the heart valves or for that matter valves.
What is the purpose of heart valaves?
The reason we have valves in our heart is to direct the flow of blood in one direction. This ensures that it is able to circulate through the body.
