The veins are neither strong nor thick of the blood vessels. On the contrary the veins are thin and thin walled. The arteries are strong and thick. They have to bear the pressure of the blood that comes from the heart.
Most of the volume of blood in the circulatory system is located in the veins and venules. These blood vessels act as reservoirs, holding the majority of the body's blood volume and allowing for regulation of blood pressure and distribution of blood to tissues.
Blood vessels transport blood throughout the body. There are different types of blood vessels - the main ones being arteries, veins and capillaries. Arteries carry blood away from the heart, veins carry blood towards the heart and capillaries are where gas exchange occurs.
The heart is the organ that receives blood from the veins and pumps it into the arteries.
Arteries carry oxygenated blood away from the heart to the body's tissues, while veins carry deoxygenated blood back to the heart. This key difference in oxygenation levels within the blood is what distinguishes arteries from veins.
