The systemic circulation carries blood between the heart and the rest of the body. In contrast, the pulmonary circulation brings blood between the heart and the lungs.
The arteries carry blood away from the heart. The aorta is the main artery that carries oxygen rich blood from the heart to the rest of the body.
The superior and inferior vena cava deliver blood from the body into the heart, the aorta brings blood from the heart into the rest of the body.
The superior vena cava brings blood back from the upper part of the body. The inferior vena cava drains the rest of the body.
Deoxygenated blood returns to the heart from the rest of the body via the inferior vena cava which brings blood from the lower half of the body and the superior vena cava which brings blood from the upper half of the body. The inferior and superior vena cava join at the right atrium of the heart.
Arteries. Or you might mean the aorta, the large artery coming directly out of the heart with others brancing from it.
the heart pumps blood to the aorta which distributes it to the rest of the body.
The heart is the organ responsible for pumping blood to the rest of the body.
Blood comes to the right atrium of the heart from the body.
Arteries carry blood away from the heart, whereas veins carry blood toward the heart. In general, arteries carry oxygenated blood and veins carry deoxygenated blood. This is NOT the case for the pulmonary vein, which brings freshly oxygenated blood back to the left side of the heart so that it can be distributed to the rest of the body.
Veins carry the blood back to the heart from the body. Arteries carry blood from the heart to the rest of the body.
From digestion to inter-cellular space through to blood vessels, in which the blood then brings the molecules to rest of the body
