Innate Immunity vs. Adaptive Immunity: A Clear Comparison
Innate and adaptive immunity are often mixed up, but they do different jobs. Innate immunity is the body’s fast, broad first response. It uses barriers like skin, early inflammation, and quick-acting cells such as macrophages and natural killer cells.
Adaptive immunity is slower to build at first, but it is more targeted. It includes B cells, T cells, antibodies, and immune memory. That memory helps the body respond more efficiently if it sees the same threat again.
A helpful way to think about it: innate immunity starts the response, and adaptive immunity refines it. That makes it easier to place common terms like inflammation, antibodies, and natural killer cells in the right context.
