How does the hoof receive oxygenated blood?

Gas exchange happens in capillaries, the tiny vessels between arteries and veins. Oxygen-rich blood is delivered to the hoof by arteries, then flows through a dense capillary network in the hoof tissues. Across the thin capillary walls, oxygen diffuses into the hoof cells while carbon dioxide diffuses back into the blood to be carried away. This diffusion is how the hoof tissue actually receives its oxygen. Veins return the deoxygenated blood, and lymphatics carry fluid and immune components, not blood.
