Immune function

The immune system is the body's defense mechanism against infections and diseases. It comprises various cells, tissues, and organs that work together to identify and destroy harmful invaders like bacteria, viruses, and parasites. When the body detects these threats, the immune system responds by activating immune cells that target and eliminate them. It also remembers past infections, allowing for quicker and stronger responses to future encounters with the same pathogen. A healthy immune system is crucial for maintaining overall health and protecting the body from illness.
