Why is the Nail Bed Pink?
Do you ever wonder why your nail bed is pink? I have to admit that I never thought about it. I’m very fair and have lots of pink in my skin, so I just figured I was pink under my nails, too. 😂😂
Doug Schoon has the answer for us.
“Arteries carry blood from the heart to the nail bed and other surrounding tissues, including the matrix. Two different arteries supply the nail unit and are located on the side of the finger. “
“These pass through the lateral nail fold and run deep into the tissue of the nail bed. The pinkish appearance of the nail bed is due to its rich supply of tiny capillaries that constantly feed, clean, and supply oxygen to these living cells. These capillaries are the smallest blood vessels.
They are arranged parallel to the length of the finger (or toe), looping back on themselves to ensure efficient blood flow. Their job is to maximize the amount of nutrients and oxygen delivered to the tissue. They connect with other capillaries that join veins. The veins remove waste products and carbon dioxide created by metabolism in the cells, which keeps these tissues clean and healthy. The blood-filled capillaries are the reason that healthy nail beds have a pinkish coloration. Changes in the appearance of the nail bed can indicate various internal diseases or local conditions. For example, a pale or white nail bed may suggest anemia, while a bluish nail bed can indicate low blood oxygen. The nail bed and surrounding areas also have a rich supply of nerves, contributing to the high sensitivity of the fingertips.”
