Immune System

(En español: Sistema inmunológico)

Say: ih-myoon sis-tum

This body system, which includes white blood cells and lymph nodes, helps protect your body from disease. The immune system has different parts, all of which work together to fight off outside invaders like germs. Every day your immune system does battle to keep you healthy and feeling your best.
