Immune System | Science 3D class

Discover how your body fights against bacteria and viruses by using the extensive network of cells, tissues, and organs that make up your immune system. The immune system coordinates the body's defences against any dangers to your health. Without it, you'd be exposed to countless bacteria, viruses, and poisons that might fatally affect you from anything as simple as a paper cut or a common cold. So, let's learn how does the immune system function? Enjoy virtual science class by Ash and Alex.
