Study Notes
Innate Immunity Overview
- Innate immunity is the body's first line of defense against infection.
- Physical barriers, like skin and mucous membranes, prevent pathogens from entering the body.
- Chemical barriers, such as stomach acid and saliva enzymes, destroy pathogens.
- White blood cells (macrophages, neutrophils) identify and engulf invaders.
- Inflammation, characterized by redness, heat, and swelling, isolates and eliminates harmful agents.
- Fever inhibits pathogen growth by raising body temperature.
- The complement system is a group of proteins that destroy bacteria.
- Innate immunity is non-specific, targeting any invading pathogen.
- Innate immunity acts rapidly, within minutes to hours.
- Innate immunity is crucial for protecting the body from common threats.
