Immune defenses rely on living cellular soldiers fighting microbial invaders
The human organism functions as a cooperative republic of millions of living cells rather than a single static machine. White blood cells act as defensive soldiers, actively engulfing and destroying invading bacteria during infections. Health depends on maintaining the vitality of these cellular citizens through adequate nutrition, fresh air, and rest. Inflammation is not a disease in itself, but the visible battlefield where living cells combat micro-organisms.
