Chris: Innate Defense: Cells & Function, Kartoniert / Broschiert

Klappentext

Our body's first line of defense, the innate immune system, is a complex army of cells and processes working tirelessly. These unsung heroes include:
Physical Barriers: Skin and mucous membranes form a formidable frontline, like a castle wall, repelling invaders.
Phagocytes: These white blood cell warriors, like macrophages and neutrophils, engulf and destroy foreign microbes, acting as the system's janitors.
Chemical Warfare: Tears, saliva, and stomach acid contain antimicrobial substances that neutralize or kill pathogens before they can infiltrate.
Inflammation Brigade: When a breach occurs, immune cells trigger redness, swelling, and heat, isolating the threat and attracting reinforcements.
Innate immunity acts swiftly and broadly, providing a vital first response while the adaptive immune system gears up for a more targeted attack. This intricate teamwork safeguards our health constantly
