Veins are where you will find deoxygenated blood that is returning to the heart to be sent to the lungs.

Copper, gold, silver, to name only three.
In other plants, netted venation occurs, in which the large veins branch repeatedly as they enter the blade. These produce smaller, interconnecting branches as well.
Blood is transported in arteries, veins, and capillaries. Arteries are the vessels that take blood from the heart. Veins are the vessels that take blood back to the heart, and capillaries are the tiny vessels that attach the arteries and veins. Transport of oxygen and nutrients occurs on the capillary level.
Atherosclerosis occurs when LDL (Low Density Lipoproteins) get oxidized. Since the plasma in the arteries contains plenty of oxygen to oxidize the LDL's it occurs mostly in arteries. In the veins, there is little oxygen to be found, so it is much more likely to happen in the arteries for that reason.
Heart to arteries to capillaries to veins.

The capillaries serve as the bridge between arteries and veins where the exchange of chemical substances inside the body occurs.
Gas exchange primarily occurs in the capillaries, not in arteries or veins. Arteries carry oxygen-rich blood away from the heart to tissues, while veins return oxygen-poor blood back to the heart. The capillaries, which are small blood vessels that connect arteries and veins, facilitate the exchange of oxygen and carbon dioxide between the blood and surrounding tissues. Therefore, gas exchange does not take place directly in arteries or veins.
Saddle-reef gold is found in Hill End, New South Wales. This occurs in quartz veins.
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.
