‘The human immune system is an amazing, complex, intricate biological framework of structures and processes that is exquisitely designed to protect the body from a wide variety of pathological agents.
It is composed of countless cellular and subcellular mechanisms that gives it an intelligence and flexibility that is nothing short of miraculous. B cells and T cells, and Natural Killer cells (that’s really what they’re called!) and immunoglobulins all coordinated and synchronized and astoundingly effective, in most cases the immune system is all that stands between us and potential disaster caused by bacterial, viral and environmental invasion. Without an immune system you would be dead in hours.’
