Intravenous (IV) access involves inserting a needle into a vein, usually in the arm, to administer medications, fluids, or to draw blood, allowing for direct entry into the bloodstream for immediate effect.

Intraosseous (IO) access, on the other hand, involves penetrating the bone to reach the bone marrow, providing an alternative route for the delivery of medications and fluids when IV access is not feasible, typically used in emergency situations due to its rapid absorption into the circulatory system.
