The veins collect blood from the capillaries, which are tiny vessels leading to and from each living cell in the body. Carbon dioxide and other waste products are returned to the blood by cells, and are removed in the lungs, kidneys, liver, and other excretory organs.
Veins
They collect (used) blood for re-use.
venules
The hepatic portal vein is formed by the confluence of the superior mesenteric veins, the splenic veins and also receives blood from the inferior mesenteric, gastric, and cystic veins.

Blood is drained from the liver through the hepatic veins, specifically the right, left, and middle hepatic veins. These veins collect oxygen-depleted blood from the liver and transport it to the inferior vena cava, which then carries the blood back to the heart for re-oxygenation.
The fluid that is in the dural venous sinuses is venous blood that originates from the brain or cranial cavity. They collect blood from veins on the surface of the brain. Blood from the sinuses empties into the internal jugular veins
venal blood in simple terms in the blood found in the veins, it is the blood that has dissolved carbon dioxide in it, so appearing greenish blue under the skin. The veins collect the CO2 from the cells of the body and carry it to the lungs for removing the CO2 and dissolving fresh O2 into the blood.

The heart. Specifically through the Vena Cava.
No they do not. "Veins" are in fact, the blood vessel that moves blood to the heart so that it can get moved to the lungs in order to gain oxygen. "Arteries" are the blood vessel that moves blood away from the heart so that way the various body parts can gain that oxygen to do there thing.
