How does de-oxygenated blood exit the hoof?

Deoxygenated blood exits the hoof through the venous drainage system, specifically the digital veins. Blood travels into the hoof via the palmar (digital) arteries to supply oxygen, then passes through capillaries where gas exchange occurs. The carried-away blood returns as deoxygenated blood through the digital veins, which drain the hoof and carry it back up the leg. Arteries, like palmar and digital arteries, bring oxygen-rich blood in, and capillaries are the exchange sites, so they’re not the exit route.
