The model shows similar drug administration like intravenous, but now it is administered to arteries and it reaches tissues first then goes via veins to other tissues.
Intra-arterial administration is a specialized route of drug delivery where drugs are directly injected into an artery. This approach is typically used when high drug concentrations need to be delivered directly to a specific organ or tissue, bypassing the venous system initially. It ensures that the drug first reaches the targeted tissue before entering systemic circulation.
