Your immune system is a marvel. It protects the body from foreign invaders such as viruses, bacteria, fungi, and toxins. Your immune system is divided into two parts: the part you were born with (innate or non-specific system) and the function you create due to your exposure to the environment (adaptive acquired or specific system). The immune system comprises proteins, several organs, and cells like the thymus and lymph glands. A balanced immune system is the most robust defense against illness and infection. With good immunity, you all be able to fight dangerous chemicals or changes in your body. Your best protection against disease and infection is a healthy immune system. You wouldn't be able to fend off toxic substances or changes in your body if you didn't have them.
