👉 Veins that are located closer to the skin's surface are called superficial veins, while those that run deeper beneath the skin are called deep veins. The term "anne veins" is a colloquial term for superficial veins, derived from the Latin word "annulus," meaning ring. These veins are often visible as small, thin lines under the skin and can be easily seen when one presses on them gently. They play an important role in returning blood to the heart after it has been pumped out to the body's tissues.
