innate immunity is a special defense mechanism present in our body since birth that helps fight against pathogens.

Immunity is the body's ability to defend against harmful invaders.

innate immunity is non-specific and includes physical and chemical barriers.

The complement system consists of serum proteins that identify and destroy pathogens.

The second line of defense in innate immunity involves cells like neutrophils, monocytes, and macrophages that can perform phagocytosis.

Pathogen recognition receptors on cells help identify and respond to pathogens.

Toll-like receptors are an example of pattern recognition receptors that trigger the release of cytokine molecules to activate other immune cells.

cytokine molecules like interleukins and interferons help coordinate the immune response.

innate immunity plays a crucial role in activating adaptive immunity and maintaining overall immune function.
