The blood enter first to superior and inferior vena cava after the vena cava it will enter to right atrium
The primary artery that blood flows out of the heart to the rest of the body is the aorta. The aorta is also the largest artery of the body.
Respratory systen
Veins carry the blood back to the heart from the body. Arteries carry blood from the heart to the rest of the body.
Artery: Vessels whereby Blood flows from the heart to the lungs & rest of organs and body (rich in oxygen). Vein: Vessels whereby Blood flows from organs and body to the heart (low in oxygen).
After taking oxygen from the lungs the blood travels to the left atrium of the heart. From here the blood is pumped to the left ventricle. The left ventricle then pumps the oxygenated blood into the aorta through which it flows to the rest of the body.
arteries send blood to the rest of the body, from the heart; viens send it back to the heart from the body.
Blood enters the right atria from the superior and inferior vena cava. Then it flows down into the right ventricle. Then to the lungs. Back to the left atria. Down into the left ventricle and out the the rest of the body.
The left ventricle. Blood flows from your body back to the right atrium through the right ventricle then to the lungs to get oxygen. It then goes to the left atrium to the left ventricle, which is the largest, most muscular part of the heart because it pumps the oxygenated blood back to the body.
So that the rest of your body can get the blood as well. After that the blood goes back into the heart.
It is the aorta, the artery that flows directly out of the heart, taking oxygenated blood to the rest of the body. Agreed!!
Veins only carry blood away from the body and back to the heart. Arteries carry blood away from the heart. There are two main venae, the superior and the inferior venae cavae, that enter the heart carrying oxygen poor blood. Then the pulmonary artery carries that blood to the lungs, where it is oxygenated. The oxygenated blood then travels back to the heart via the pulmonary vein and then is pumped to the rest of the body through the aorta, the main artery leading to the rest of the body.
When the blood is flowing back to the heart, the blood has already given off its oxygen to the rest of the body which means it contain less oxygen concentration in the blood. and when blood is flowing from the heart to the rest of the body, the blood contains high level of oxygen because they were being given oxygen by the lungs which passes along the heart and the heart pumps it to the rest of the body.
