The immune system is essential for protecting the body against infections and diseases caused by pathogens such as bacteria, viruses, and fungi. It identifies and neutralizes harmful invaders while also maintaining a memory of past infections to respond more effectively in the future. Additionally, the immune system plays a role in identifying and eliminating abnormal cells that can lead to cancer. Overall, a well-functioning immune system is crucial for maintaining overall health and well-being.
