Veins have strong celular walls & also contain valves.The valves stop blood from pooling backwards as the heart pumps blood around.
Its important to remember that blood in the veins is under low pressure & are returning blood back towards the heart & are de oxygenated.Arteries are larger & the blood in them is under very high pressure & is highly oxygenated.
Blood from veins is much darker as it has less oxygen being carried.Arterial blood is much lighter red colour as it is highly oxygenated.
yes....it has a wider lumen than arteries and carries more blood
Not really. Veins just carry blood to the heart, where it is pumped with fresh oxygen.
Yes, because of their great elasticity arteries can function as blood volume reservoirs during times of low metabolic output.
Blood vessels
veins
Hi, veins function as a blood reservoir as they carry the blood, this giving them the name (reservoir)
Veins, liver and spleen
true
veins and venules
The veins are generally considered blood reservoirs. This is due to their ability to hold a lot of volume at a relatively low pressure (due to their thin walls compared to arteries). They generally hold 50-80% of the entire blood volume of the body.
veins serve as pathways for blood circulation.they carry blood from the capillaries toward the heart.

No, I believe that the pulmonary system contains more blood. This is because the veins act as "reservoirs" and can contain up to 65% of the body's blood supply.
The heart PUMPS BLOOD through the arteries throughout your body. Veins take blood to your heart, arteries take blood away. some people think the heart pumps blood into your veins but that is NOT true. Your veins take the blood to your heart, the arteries take the blood away from your heart.
Veins function as blood reservoirs. For example, in hemorrhage accompanied by a drop in arterial blood pressure, sympathetic nerve impulses reflexly stimulate the muscular wall of the veins. The resulting venous constrictions help maintain blood pressure by returning more blood to the heart. This mechanism ensures a nearly normal blood flow even when as much as 25% of blood volume is lost..
Veins
Veins, arteries and capillaries are the pathways in which blood is carried throughout the body.
