Immune System

18 lectures, 3 hr 24 min in all

The immune system is one of the most complex and fascinating systems in the human body—a biological defense network shaped by millions of years of evolution. This playlist unpacks how it works, from the first line of defense to its most specialized soldiers, revealing how it protects us from threats like rabies, tuberculosis, and smallpox. But not all battles are won. We explore how the immune system struggles against cunning enemies like cancer, and how scientists are helping it fight back. What happens when viruses are genetically engineered—or when they evolve faster than we can respond? And what role do vaccines play in training our immune system and stopping pandemics before they start? From ancient plagues to cutting-edge biotechnology, this series dives deep into the inner workings of our most vital protector—and the invisible wars happening inside us every day.
