The blood is stopped from flowing backward by four sets of valve. Between the right artrium and the right ventricle is the tricuspid ( = three flaps) valve. Between the left artrium and the left ventricle is the bicuspid ( = two flaps) valve.
To the lungs. Arteries and veins are usually named after the organ they carry blood to and from. It will help you a lot if you learn the scientific names for organs, for example:
The pulmonary vein returns blood to the left atrium.
Blood returns from the body to the right atrium, and is pushed to the lungs by the right ventricle. Once oxygenated, the blood flows back to the left atrium, and is pushed out into the arteries by the left ventricle.
There is often confusion over the pulmonary arteries(which carry deoxygenated or venous blood) to the lungs, with the pulmonary veins, which carry oxgenated or arterial blood back to the heart. The terminology is based on whether blood is flowing "to" the heart (veins) or "away" from the heart (arteries).
The Right ventricle pushes deoxygenated blood from through the pulmonary valve into the pulmonary artery.
The heart, more specifically the right ventricle.
The right ventricle pumps blood into the lungs.
Deoxygenated. The blood is carried by the pulmonary arteries from the heart to the lungs to replenish the oxygen.
Arteries carry oxygenated blood away from the heart.
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.
Away. Arteries carry blood away from the heart. The blood, they carry, is oxygenated, with the exception of the pulmonary arteries. While pulmonary arteries also carry blood away from the heart (to the lungs), the blood is deoxygenated.
Pulmonary arteries and pulmonary veins are two different items. The pulmonary artery takes deoxygenated blood from the heart and into the lungs so that the blood can be oxygenated. The oxygenated blood then returns to the heart, via the pulmonary veins, in order to be pumped into the system circulation.
Pulmonary Arteries
Pulmonary Arteries.
Pulmonary arteries carry oxygenated blood away from the heart. Veins carry blood to the heart.
The vessel that carries blood from the heart to the lungs is called the pulmonary vein. It is one of the few veins that carry oxygenated blood to the heart. The oxygenated blood enters the atrium of the heart.
Arteries always carry blood from the heart. In this case, the artery is the aorta.
The blood vessels that carry the blood from the heart to the lungs are the pulmonary arteries. Blood returns from the body and is pumped by the right ventricle to the lungs, through the pulmonary arteries. The blood returns to the left side of the heart through the pulmonary veins.
The Pulmonary arteries carry deoxygenated blood from the lungs to the heart.
