Describe the primary difference between innate and adaptive immunity in terms of their response time and specificity.

Innate immunity is a rapid, non-specific response, while adaptive immunity is a slower, highly specific response.

Explain the role of dendritic cells in bridging the innate and adaptive immune systems.

Dendritic cells ingest pathogens and present antigens to T cells, activating the adaptive immune response.

MHC proteins are produced by normal cells. Natural Killer Cells check cells for MHC; if absent, the NK cell destroys the cell.

Helper T-cells activate other immune cells and create memory cells, while cytotoxic T-cells kill infected cells.

Immune System: Innate and Adaptive Immunity Explained

3 key concepts

1
The immune system is divided into two main parts: innate and adaptive immunity.
2
Innate immunity includes physical barriers like skin and mucous linings, as well as chemical barriers such as lysozyme and stomach acid.
3
Dendritic cells link the innate and adaptive immune systems by presenting antigens to T cells.
