What does the blood travel through to return to the heart?

Answer 1

Starting in the right atrium, the blood flows through the tricuspid valve to the right ventricle. Here it is pumped out the pulmonary semilunar valve and travels through the pulmonary artery to the lungs. From there, blood flows back through the pulmonary vein to the left atrium. It then travels through the mitral valve to the left ventricle, from where it is pumped through the aortic semilunar valve to the aorta. The aorta forks, and the blood is divided between major arteries which supply the upper and lower body. The blood travels in the arteries to the smaller arterioles, then finally to the tiny capillaries which feed each cell. The (relatively) deoxygenated blood then travels to the venules, which coalesce into veins, then to the inferior and superior venae cavae and finally back to the right atrium where the process began.

Answer 2

Blood returns to the heart from the body through the Vena Cava and from the lungs through the Pulmonary Vein . So mainly blood returns to the heart through Veins .

Answer 3

Blood travels from the heart to the heart to the lungs and then back to the heart. It is then pumped to all parts of the body.
