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", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/3/38/421/704/3384217047_b.jpg", "price_data" : { "retail_price" : "16.99", "online_price" : "16.99", "our_price" : "16.99", "club_price" : "16.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
