This is one of the ultimate question that is asked by any body! I have been expecting this question for my life! My answer is purely a guess work and should not be taken as authentic answer. The answer is no. There is no such valve there and at inferior vena cava and the atrium too. Similarly, there is no valve when the pulmonary veins enter at the left atrium also. But then you have very thin valves in the veins, in case of lower extremities. You have to see the figure in some anatomy book. There is no reason as to why such valve should not be present here also. The veins enter the atria making an angle to the wall as well. So when the atria contracts, the opening of the veins get closed and the blood does not go back in the venous system.

∙ 9y agoNope. The vena cava leads directly into the right atrium and the closest valve to that is the tricuspid between the right atrium and ventricle.
There is no valve in this area!

What keeps the blood from flowing back into the right atrium after it has entered the right ventricle?
The tricuspid valve prevents the backflow of blood to the right atrium..The tricuspid valve separates the right atrium from the right ventricle. It opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle. It closes as the right ventricle contracts, preventing blood from returning to the right atrium; thereby, forcing it to exit through the pulmonary valve into the pulmonary artery.
What is the correct sequence of nerves that exit the spinal cord going from superior to inferior?
cervical, thoracic, lumbar, sacral nerves
Openings provide exit of spinal nerves?
The spinal nerves exit from the vertebral column through openings between adjacent vertebrae. These openings, called intervertebral foramina, are located just in front of the facet joints. They exit from what are called intervertebral foramina (foramen means opening).
Where do the cranial nerves exit?
The cranial nerves exit from the brain inside the cranial cavity.
If the blood is moving to the upper part of the body it will exit through way?
if the bloos is moving to the upper part of the body it will exit through what?
The heart from vena cavae to the aorta?
Six large veins carry blood to the heart: the superior vena cava and inferior vena cava carry blood from the body to the right atrium, and four pulmonary veins carry blood from the lungs to the left atrium. Two arteries, the pulmonary trunk and the aorta, exit the heart. The pulmonary trunk, arising from the right ventricle, splits into the right and left ventricle, carries blood to the rest of the body.
Area where the great vessels leave the heart?
Four main blood vessels enter/exit the heart: two veins and two arteries. Oxygenated blood enters the left ventricle through the pulmonary vein. This same blood is then pumped out of the left atrium via the aorta. Meanwhile, de-oxygenated blood enters the heart in the vena cava; before leaving through the pulmonary artery.
How does blood flow from right atrium to renal veins?
Right atrium to the right ventricle through the pulmonary arteries to the lungs back to the pulmonary veins to the left atrium and then left ventricle. From the left ventricle blood will exit the heart through the aorta. The renal arteries branch directly off of the abdominal aorta which flow to the kidneys. Blood will filter through the kidneys and return to the bloodstream through the renal veins which empty into the inferior vena cava which then empties into the right arium of the heart.
What- are the parts of the heart and their functions?
Some of the parts of the circulatory system and what they do:* Aorta - the body's largest artery. It takes oxygenated blood from the left ventricle out to the body.* Arteries - carry blood AWAY from the heart* Vena Cava - the largest vein in the body, it carries blood from the body back to the heart (consists of superior and inferior vena cava)* Veins - carry blood TOWARDS the heart* Pulmonary Arteries - carry deoxygenated blood from the right ventricle to the lungs.* Pulmonary Veins - take oxygenated blood from the lungs to the left atrium* Oxygenated blood - blood carrying oxygen after leaving the lungs (blood passes through pulmonary veins back to the heart, enters left atrium, pumped to body by left ventricle)* Deoxygenated blood - blood carrying little oxygen, and carbon dioxide (blood returning the the right atrium, and pumped by the right ventricle through the pulmonary arteries to the lungs)Parts of the Heart* Right Atrium - receives deoxygenated blood from the body, mostly through the inferior and superior vena cava* Right Ventricle - pumps deoxygenated blood into the pulmonary arteries* Left Atrium - receives oxygenated blood from the lungs* Left Ventricle - pumps oxygenated blood into the aorta* Coronary Vessels - supply the heart muscle with its blood supply* Bicuspid Valve - (mitral valve) valve between the left atrium and the left ventricle.* Tricuspid Valve - valve between the right atrium and the right ventricle.----The aorta is the largest single blood vessel in the body. It is approximately the diameter of your thumb. This vessel carries oxygen-rich blood from the left ventricle to the various parts of the body.The superior vena cava is one of the two main veins bringing deoxygenated blood from the body to the heart. Veins from the head and upper body feed into the superior vena cava, which empties into the right atrium of the heart.The inferior vena cava is one of the two main veins bringing de-oxygenated blood from the body to the heart. Veins from the legs and lower torso feed into the inferior vena cava, which empties into the right atrium of the heart.The right atrium receives de-oxygenated blood from the body through the superior vena cava (head and upper body) and inferior vena cava (legs and lower torso). The sinoatrial node sends an impulse that causes the cardiac muscle tissue of the atrium to contract in a coordinated, wave-like manner. The tricuspid valve, which separates the right atrium from the right ventricle, opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle.The right ventricle receives de-oxygenated blood as the right atrium contracts. The pulmonary valve leading into the pulmonary artery is closed, allowing the ventricle to fill with blood. Once the ventricles are full, they contract. As the right ventricle contracts, the tricuspid valve closes and the pulmonary valve opens. The closure of the tricuspid valve prevents blood from backing into the right atrium and the opening of the pulmonary valve allows the blood to flow into the pulmonary artery toward the lungs.The left atrium receives oxygenated blood from the lungs through the pulmonary vein. As the contraction triggered by the senatorial node progresses through the atria, the blood passes through the mitral valve into the left ventricle.The left ventricle receives oxygenated blood as the left atrium contracts. The blood passes through the mitral valve into the left ventricle. The aortic valve leading into the aorta is closed, allowing the ventricle to fill with blood. Once the ventricles are full, they contract. As the left ventricle contracts, the mitral valve closes and the aortic valve opens. The closure of the mitral valve prevents blood from backing into the left atrium and the opening of the aortic valve allows the blood to flow into the aorta and flow throughout the body.The pulmonary arteries are the vessels transporting de-oxygenated blood from the right ventricle to the lungs. A common misconception is that all arteries carry oxygen-rich blood. It is more appropriate to classify arteries as vessels carrying blood away from the heart.The pulmonary veins are the vessels transporting oxygen-rich blood from the lungs to the left atrium. A common misconception is that all veins carry de-oxygenated blood. It is more appropriate to classify veins as vessels carrying blood to the heart.The chordae tendineae are string-like in appearance and are sometimes referred to as "heart strings." They connect the heart muscles to the valves.The tricuspid valve separates the right atrium from the right ventricle. It opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle. It closes as the right ventricle contracts, preventing blood from returning to the right atrium; thereby, forcing it to exit through the pulmonary valve into the pulmonary artery.The mitral valve (bicuspid valve) separates the left atrium from the left ventricle. It opens to allow the oxygenated blood collected in the left atrium to flow into the left ventricle. It closes as the left ventricle contracts, preventing blood from returning to the left atrium; thereby, forcing it to exit through the aortic valve into the aorta.The pulmonary valve separates the right ventricle from the pulmonary artery. As the ventricles contract, it opens to allow the de-oxygenated blood collected in the right ventricle to flow to the lungs. It closes as the ventricles relax, preventing blood from returning to the heart.The aortic valve separates the left ventricle from the aorta. As the ventricles contract, it opens to allow the oxygenated blood collected in the left ventricle to flow throughout the body. It closes as the ventricles relax, preventing blood from returning to the heart.

Describe the path of blood flow through the heart?
Venous blood enters the heart through the superior and inferior venae cavae into the right atrium. From the atrium they exit the tricuspid valve into the right ventricular. The blood exits the right ventricle through the pulmonary valve into the pulmonary veins towards the lungs. Oxygenated blood returns through the pulmonary veins into the left atrium, Then, it enters the left ventricle through the mitral valve. From the left ventricle it passes through the aortic valve, and into the aorta.
How does the blood flow through the heart?
Beginning with the return of blood to the heart from the systemic circulation, blood enters the right atrium, then the right ventricle, through the pulmonary trunk to the pulmonary arteries and the lungs, through the pulmonary veins, into the left atrium, left ventricle and is then pumped into the aorta.blood enters and exits the heart through the arteries. blood will exit the right atrium through the pulmonary artery and head towards the lungs. once blood is oxygenated by the lungs it will come back to the heart through the coronary artery and enter in the left atrium.
What chamber does the aorta exit to?
The heart has four chambers, two associated with the pulmonary circuit (right atrium and right ventricle) and two with the systemic circuit (left atrium and left ventricle). This side has the aorta connected to it.The left ventricle has a greater workload and is much more massive than the right ventricle, but the two chambers pump equal amounts of blood but the distance to be pumped is greater for the left side.
Did clamshells exit before time?
no because if they did they wouldn't exit right know! no because if they did they wouldn't exit right know!
