HI BUDDY

HERE IS UR ANSWER

HOPE U UNDERSTAND

Anatomical terminology. Veins are blood vessels that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart.For example, sometimes vascularity can be a marker of excess stress, with increased secretion of the stress-hormone cortisol, or over-production of the hormone aldosterone, which causes your body to hang on to sodium. As a result, your body retains water and makes your veins swell, he says.

Any of the blood vessels that carry blood toward the heart from the body's cells, tissues, and organs. Veins are thin-walled and contain valves that prevent the backflow of blood. All veins except the pulmonary vein carry blood with low levels of oxygen.
