yes,to circulate more blood .
Arteries. Because the capilaries connect the arteries to the vein as Veins carries blood back to the heart.
Venules are the microscopic vessels that continue from the capillaries and merge to form veins. Veins carry blood back to the atria, leading to the heart...
Veins take blood back to the heart.
The heart pumps it. When your heart beats it squeezes blood in the heart into the arteries and from the arteries to the veins and from the veins back into the heart.
They are called the Pulmonary Veins. They are the only types of veins that carry Oxygen-Rich blood (usually Arteries do that). These Pulmonary Veins carry blood that has been re-oxygenated in the lungs back to the heart for distribution to the body through the Aorta/Descending Aorta. Hope this helped!
veins
The venous system, or "veins" are responsible for bringing blood back from your peripheral body to the right side of the heart, where it is sent to the lungs for reoxygenation. Veins have one way valves that function to maintain a stable pressure in the venous system, while increasing the efficiency of the heart by preventing backflow of blood in between ventricular beats.
Veins
Veins carry blood back to the heart. In contrast, arteries carry blood away from the heart.
Veins carry deoxygenated blood back the heart.
No, from the heart. The veins carry the blood back to the heart.
