In which tissue layer is an intradermal injection delivered?

Explanation:
Intradermal injections are delivered into the dermis, the layer just beneath the outer epidermis. The dermis is where you find a network of connective tissue, blood vessels, nerves, and immune cells, which makes it ideal for small-volume tests and for creating a localized immune response. When done correctly, the fluid forms a small raised wheal in the skin, indicating the injection is within the dermal layer. The other options describe different routes: into muscle (intramuscular), into a vein (intravenous), or into the fatty subcutaneous tissue (subcutaneous injection).
