How Your Body Fights Off a Common Cold

How Your Body Fights Off a Common Cold is a free, self-paced learning path in Medicine & Health Sciences, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the primary viral agents causing human respiratory infections; explain the role of physical barriers in preventing infection; categorize the innate and adaptive immune system functions.
