Superficial of Blood Vessels

Unlike deep veins, they’re not surrounded by muscle. Instead, your superficial veins can be found just underneath your skin. So, you can easily see them. Your superficial veins carry blood from your outer tissues near the surface of your skin to your deep veins (via the perforating veins).

The outermost layer, which attaches the vessel to the surrounding tissue, is the tunica externa or tunica adventitia. This layer is connective tissue with varying amounts of elastic and collagenous fibers.
