Blood transported by the pulmonary veins returns to the left atrium of the heart. The pulmonary vein carries oxygenated blood away from the lungs.
Blood flows from the right atrium of the heart into the right ventricle to the pulmonary artery to the lungs where the blood is oxygenated. From there it flows to the pulmonary vein to the left atrium and ventricle, then to the aorta.
right atrium -> right ventricle -> pulmonary artery -> pulmonary vein -> left atrium -> left ventricle -> aorta
The left atrium receives oxygenated blood from the pulmonary vein.
Right atrium > tricuspid valve > right ventricle > pulmonary semilunar valve > pulmonary arteries > lungs > pulmonary veins > left atrium > bicuspid valve > left ventricle > aortic semilunar valve > aorta > arteries > arterioles > capillaries > venues > veins > superior/inferior vena cava > right atrium (again)
The pathway of a red blood cell from the right atrium and back. (1) right atrium -> (2) right AV valve -> (3) right ventricle -> (4) pulmonary valve -> (5) pulmonary trunk -> (6) pulmonary arteries -> (7) lungs, for exchange of gases (not shown) -> (8) pulmonary veins -> (9) left atrium -> (10) left AV valve -> (11) left ventricle -> (12) aortic valve -> (13) aorta -> (14) other systemic vessels -> (15) inferior and superior venae cavae -> (16) back to the right atrium The pathway from 5 to 8 is the pulmonary circuit. The pathway from 13 to 15 is the systemic circuit.
Yes, blood from both the inferior and the superior vena cava flow into the right atrium. Blood from the pulmonary veins coming from the lungs flow into the left atrium.
Blood that comes in to the right atrium comes from the pulmonary vein.
The pulmonary vein carries blood from the lungs to the right atrium. This blood is oxygen-rich.
The Pulmonary Semilunar Valve allows blood from the right atrium into the pulmonary trunk.
Pulmonary viens conduct blood away from the lungs.This blood is carried to the right atrium of the heart.
