The first organ to receive oxygen-rich blood would be the heart. The right ventricle pumps de-oxygenated blood to the lungs. The lungs provide oxygen via interaction with capillaries which in turn sends the oxygen-rich blood back to the left atrium which is found in the heart.

Oxygenated blood passes through what valve first?
The mitral valve between the left atrium and ventricle.
What is importance of pulmonary circulation?
Pulmonary circulation is blood supply to the lungs. This is important for two reasons. First, like all organs, the lungs have to have oxygen themselves in order to function. Second, blood has to go through the lungs in order to become oxygenated. The pulmonary vein is the only vein in the body that carries oxygenated blood. Systemic circulation is important for two reasons also. First, and simplest, is the fact that every cell in the body has to have oxygenated blood to function. Without oxygenated blood, the cells will begin to infarct, or die. Second, systemic circulation creates what's called perfusion pressure. Simply put, it's the pressure required to allow the organs to pull the oxygen from the blood. As blood pressure goes down, the body's ability to pull in oxygen from the blood also decreases.
What happens in the right atrium?
The atria are the two upper chambers of the heart (the ventricles are the lower two) The atria are the 'filling' chambers, so blood entering the heart passes through the atria first, which then push it down into the ventricles. The two largest veins in the body (the superior and inferior venae cavae) empty deoxygenated blood returning from the body into the right atrium. The right atrium then contracts, pushing the blood into the right ventricle. The right ventricle then pumps the deoxygenated blood to the lungs where it is oxygenated. After leaving the lungs, the newly oxygenated blood is returned via the pulmonary veins into the left atrium. The left atrium then contracts and pushes the blood into the left ventricle, which pumps the oxygenated blood around the rest of the body.
What is the structure between two heart chambers that allows blood to go only one way?
The human heart is composed of four chambers. They are the right atrium, right ventricle, left atrium and left ventricle. The heart also contains four valves that ensure that blood flows continuously through the heart in the correct direction. Oxygen depleted blood is channeled from the body into the heart through the Inferior and Superior vena cava. It first enters the right atrium then passes through the tricuspid valve into the right ventricle. From there the blood is forced through the pulmonary valve into the pulmonary arteries and on to the lungs where it dumps carbon dioxide and picks up oxygen.The newly oxygenated blood is returned from the lungs to the heart via the pulmonary veins. It enters the left atrium, is forced through the bicuspid valve and into the left ventricle. From there the blood passes through the aortic valve into the aorta (the body's largest artery) which branches into several smaller arteries as it circulates the freshly oxygenated throughout the body
Why are the walls of the lower chambers of the heart thicker and more muscular than the walls of the upper chambers?
Some terminology first: The upper chambers = atria (singular atrium) The lower chambers = ventricles The atria are responsible for receiving blood: the right atrium receives deoxygenated blood from the body and the left atrium receives oxygenated blood from the lungs. The atria only pump this blood into the ventricles and therefore do not need particularly thick muscular walls. The ventricles on the other hand are responsible for pumping the blood received from the atria to the body. The right ventricle pumps the deoxygenated blood it receives from the right atrium out of the heart and into the lungs. On the other hand, the left ventricle is responsible for pumping the oxygenated blood received by the left atrium to the rest of the body. It is because of the this that the walls on the side of left ventricle are the thickest. The left ventricle requires "more muscle" than the right ventricle as the distance it has to pump the blood is far greater. So, SHORT ANSWER: The walls of the lower chambers/ventricles are thicker and more muscular than the walls of the upper chambers/atria because they have to pump blood out of the heart and to the body as opposed to the atria which only receive blood from the body and then pump into the ventricles.
Is freshly oxygenated blood first received by the Spleen?
Wow not even close. It's received by the left atrium of your heart.
Blood from the body is first received by the heart in the?
Blood from the body is first received by the heart in the right atrium. The blood is taken to the right ventricle and eventually to the lungs to be purified and oxygenated.
The oxygenated blood first enters the?
The oxygenated blood first enters the capillaries, then they carry the blood through other veins to the rest of the body.
Oxygenated blood passes through what valve first?
The mitral valve between the left atrium and ventricle.
Where does blood go first when it leaves the heart of the fish?
the heart to get oxygenated
The first chamber of the heart to receive oxygenated blood is what?
Left atrium.
What is the first chamber of the heart to receive oxygenated blood is?
the left atrium
When do veins carry oxygenated blood?
Only when it is the pulmonary vein, as it carries oxygenated blood to the heart. All other veins carry de-oxygenated blood which ends up going to the heart. (The pulmonary vein, however, comes from the lungs, where blood is first oxygenated and then transported to the heart.)
Why does the blood from the different parts of the body enter the heart?
The blood from the different parts of the body enters the heart through veins in order to be pumped/circulated. First through the lungs to be oxygenated and then back to the body where it can deliver the oxygen. Starting at the heart, freshly oxygenated blood is pumped to the body where the oxygen is used up by muscles etc., and the deoxygenated blood then returns to the heart. It is then pumped to the lungs where it absorbs oxygen from the air you breathe, and finally it is pumped back to the heart and the cycle begins over again.
What is the name of the first artery leaving your heart carrying oxygenated blood?
The aorta!
What blood vessel carries oxygenated blood from the heart to the rest of the body?
All the arteries, except the pulmonary artery, carries oxygenated blood from the heart (left ventricle to the aorta, then to the rest of the body), and provides systemic circulation.The aorta carries oxygenated blood from the left ventrical of the heart to the head first and then to the rest of the body through branches that get much smaller as they near the capilaries to allow gas exchange to occur between the tissues and each individual cell.
Does the aorta carry oxygenated blood out of the heart?
I think it's false but I can't be sure you might want to try someone else. I thought oxygenated blood went to teh lung by the arteries but hey better if you check with someone else uless your willing to risk it.
