It depends on what kind of control you are talking about. Blood vessel walls keep the blood traveling in the right path. Valves in the heart and veins keep it moving in the right direction in each vessel. The spleen and kidneys filter and remove impurities and waste products. The intestines add nutrients to be carried to the various body cells. The lungs add oxygen to be carried to the various body cells.
Arteries always carry blood away from the heart. Veins always carry blood back to the heart. In almost all cases, arteries carry oxygenated blood. And veins carry deoxygenated blood. The exception to this rule is that pulmonary veins carry oxygenated blood from the lungs to the heart and Pulmonary arteries carry deoxygeneted blood.
