    Capillaries in the small intenstine are the major place where drugs adminsitered this way are absorbed.

    • Inhalation

    • IV

    • Skin Popping

    • Orally

    Correct Answer
    A. Orally
    Explanation
    Drugs administered orally are absorbed mainly in the capillaries of the small intestine. The small intestine has a large surface area due to its long length and numerous folds, which allows for efficient absorption of drugs. Additionally, the small intestine is lined with microvilli, which further increase the surface area available for absorption. The capillaries in the small intestine have thin walls and a large number of pores, allowing for easy passage of drugs into the bloodstream. Therefore, drugs administered orally are typically absorbed in the small intestine, making it the major site of absorption for orally administered drugs.

    This is the most potent route of drug administration.

    Correct Answer
    Intravenous
    IV
    Explanation
    Intravenous (IV) administration is considered the most potent route of drug administration because it delivers the medication directly into the bloodstream. By bypassing the digestive system and liver metabolism, IV administration allows for rapid and complete absorption of the drug, resulting in a quick and powerful therapeutic effect. This route is commonly used for medications that require immediate action or high bioavailability. IV administration also offers precise control over dosage and allows for continuous infusion if needed.

    The Blood-Brain Barrier allows __________ molecules in, but keeps __________ molecules out of the brain.

    • Water-soluble, fat-soluble

    • Fat-soluble, water-soluble

    • Water-philic, water-soluble

    • The BBB keeps all molecules out of the brain

    Correct Answer
    A. Fat-soluble, water-soluble
    Explanation
    The Blood-Brain Barrier is a protective barrier that separates the blood vessels in the brain from the surrounding tissue. It allows fat-soluble molecules to pass through because they can dissolve in the lipid bilayer of the barrier. On the other hand, it keeps water-soluble molecules out because they cannot easily pass through the lipid bilayer. This selective permeability of the Blood-Brain Barrier helps maintain the delicate balance of substances in the brain and protects it from potentially harmful molecules.
