The human heart is a remarkable organ. Slightly larger than a human fist the heart must continuously beat over person's lifetime. Beating 80,000 to 100,000 times and pumping approximately 2,000 gallons a day the heart will have beat 2-3 billion times and pumped 50-65 million gallons of blood over a 70-90 year lifespan. The human heart is made of specialized muscle capable of sustaining continuous beating. This muscle is different than skeletal muscle that powers the arms and legs. Not being anywhere near an expert, this answer will be a layman's recollection, hopefully to be corrected when finally improved by an expert. I think that the blood passing through th right atrium is being returned from throughout the body meaning that it is high in carbon dioxide, and has reduced oxygen content. The right side of the heart pumps this blood tthrough the lungs where the CO2 is removed, and the oxygen level is replinished. The "cleaned up" blood then goes from the lungs to the left side of the heart which then pumps it out through the arteries to the rest of the body.
In simple terms.. the blood in the left side of the heart is rich in oxygen and is getting ready to be pumped to the rest of the body. The blood on the right side is low in oxygen and is getting ready to be pumped back to the lungs for a recharge of oxygen.
The right atrium is bigger than the left because it has to receive a greater volume of blood. Blood comes to the right atrium from the entire systemic circulation, while blood arrives at the left atrium from the smaller pulmonary circulation.
The blood in the left hand side of the heart is oxygen rich or oxygenated as it has just passed through the lungs.
The blood in the right hand side is de-oxygenated having used its oxygen to nourish etc. the body's cells and collect their waste including carbon dioxide.
The blood leaving the left side of the heart carries oxygen while the blood entering the right side of the heart carries carbon dioxide and wastes.
The right receives de-oxygenated blood the left receives oxygenated

The blood entering the right atrium is deoxygenated. It has to then go to the lungs to become oxygenated. From there it is dumped into the left atrium.
The right atrium receives blood from the entire body, which is a larger volume than the left atrium receives. The left atrium receives blood only from the lungs.
Blood in the left atrium has been recently oxygenated by the lungs. Blood in the right atrium is deoxygenated, and has come from the body circulation.

The right atrium is where deoxygenated blood enters the heart.
Your blood will go to right ventricle form right atrium. You have the tricuspid valve between your right atrium and right ventricle. Then your blood will go to lungs through pulmonary aorta. Here you have pulmonary valve. Then your blood will go to left atrium via pulmonary veins. You have valves in all the veins and has got no name. Your blood goes to your left ventricle form left atrium. You have got mitral or bicuspid valve here between the two. Then your blood goes to your body via systemic aorta. Here you have aortic valve to prevent the back flow.
The tricuspid is an atrioventricular valve located on the right side of the heart, between the right atrium and right ventricle. It is called a tricuspid because it has three valves. The blood flows towards the right.
You get deoxygenated or impure blood from the whole body. It enters the right atrium. Right atrium pumps the blood in right ventricle. From right ventricle blood goes to your lungs. Here the blood gets oxygenated or get purified. Then it enters your left atrium. Left atrium pumps the blood in left ventricle. Left ventricle pumps the blood to your whole body.
The right atrium is larger than the left. This size difference is because the right atrium receives blood from the entire body.
The vena cava allows blood to enter the right atrium. Unlike the rest of the heart, there are no valves separated the vena cava and right atrium. However blood backflow is not an issue because the pressure difference between the right atrium and the vena cava is not great, and when the heart pumps it partially compresses the vena cava.
the right atrium is like a container where the blood is drained from the body to be passed to the right ventricle. But the bicuspid valve acts like a one way route maintainer. which is to direct the blood flow to flow left atrium to the left ventricle only not the other way around.
well you have two atria the right atrium and left atrium but i think the right atrium has deoxygenated blood and the left atrium has oxygenated blood.
Yes, both the superior and inferior vena cava carry deoxygenated (oxygen-poor) blood and deposit it into the right atrium of the heart.
The tricuspid valve is located between the right atrium and right ventricle, and it's there because it prevents blood from flowing backward from the right ventricle to the right atrium. The tricuspid valve is located between the right atrium and right ventricle, and it's there because it prevents blood from flowing backward from the right ventricle to the right atrium.
The heart is made up of four chambers. Two atria (top half) and two ventricles (bottom half) The right atrium receives unoxygenated blood from the body and pushes it into the right ventricle. The right ventricle then pumps the unoxygenated blood to the lungs where it is oxygenated. The left atrium then receives this newly oxygenated blood from the lungs and pushes it into the left ventricle which then sends the blood (with lots of oxygen for the body to use) to the rest of the body. The blood from the body then returns to the right atrium and the cycle starts all over again.
Blood returning to the right atrium of the heart is deoxygenated.
right atrium
Two veins return deoxygenated blood to the right atrium. The superior vena cava returns blood from the head and upper body to the right atrium. The inferior vena cava returns blood from the legs and lower body to the right atrium.
Atrium
There are many differences between the right and left side of the heart. However, the major difference between these sides of the heart is that blood is taken into the left side of the heart while the right side pushes the blood through the body.
