👉 The veins of an airport are the network of blood vessels that carry oxygen-depleted blood back to the heart and lungs for re-oxygenation. They are responsible for draining deoxygenated blood from the various organs, limbs, and tissues throughout the airport. The veins are typically divided into superficial and deep systems, with the superficial veins located closer to the skin surface and the deep veins running deeper within the body. These veins play a crucial role in maintaining the overall health of the passengers, crew, and airport personnel by ensuring adequate blood flow for oxygenation and waste removal.
