In general, veins are the blood vessels that bring blood to the heart. Blood that has already been circulated to the tissues and released its oxygen returns to the heart by the superior vena cava (from the upper body) and inferior vena cava (from the lower body). Blood is then sent to the lungs to pick up oxygen, and it returns to the heart by the pulmonary veins.
Arteries are connected to veins through capillary beds in the body tissues.
the same thing all veins do, it returns blood to the heart and circulation , arteries take blood to the body
veins
The heart pumps it around the body through arteries and it the blood returns to the heart via the veins.
Veins carry deoxygenated blood from the body back to the heart.
The arteries are connected to the veins through capillaries. Blood leaves the heart through arteries, goes throughout the body, then by way of capillaries to the veins and returns to the heart.
Blood is pumped to all the body by the heart, through the arteries. It returns to the heart through the veins.
Veins always bring blood from somewhere to the heart. The pulmonary veins bring it from the lungs to the heart and is the only time when it carries oxygenated blood. All other veins carry deoxygenated blood from the body tissues back to the heart.
Deoxygenated blood is in the systemic veins. The pulmonary veins carry oxygenated blood to the heart to be pumped to body tissues.
Arteries carry oxygenated blood to the body tissues and organs. Veins carry deoxygenated blood from the tissues back to the heart and lungs where it becomes oxygenated again.
The cardiovascular system brings blood to the body. You have more than 50,000 miles of blood vessels in your body.
