Immune System
The immune system is a sophisticated network of cells, tissues and organs that defends the body against infection and foreign invaders. It has the ability to identify friend from foe and launch an appropriate response to protect us from disease. With the continued emergence of new illnesses, the immune system is essential in helping us maintain our health and fight against pathogens. It plays an important role in keeping us healthy by recognizing and eradicating invading organisms, such as bacteria, viruses and cancer cells. In addition, it helps to regulate the body's inflammatory responses and provide immunological memory, which enables us to remember previous encounters with foreign invaders and mount a quicker and more effective response in the future.
