Some of the main organs involved in the immune system include the spleen, lymph nodes, thymus, and bone marrow. Immune system, the complex group of defense responses found in humans and other advanced vertebrates that helps repel disease-causing organisms (pathogens ).

The system in humans and other animals that provides immunity by protecting against disease-causing agents, such as bacteria, viruses, parasites, and fungi. The role of the immune system — a collection of structures and processes within the body — is to protect against disease or other potentially damaging foreign bodies.

To function well, it requires balance and harmony. Any of a group of proteins secreted by a number of cell types, including macrophages and helper T cells, that regulate the function of lymphocytes and other cells of the immune system.
