How can I differentiate a vein from an artery?
How can I identify which is which when looking at them?
In most cases, arteries are deeper beneath the skin and appear more bluish or purple, while veins are closer to the surface and appear more reddish or bluish. However, it's important to note that this can vary from person to person and isn't always a reliable method of differentiation.
