Immune System and Infections Quiz

Immune System = Complex system of cells and proteins that defend the body against infection Lymphatic System = Network of tiny vessels that allows immune cells to travel between tissues of the body and the bloodstream Infection = Invasion and multiplication of microorganisms such as bacteria, viruses, and parasites that are not normally present within the body Immunity = The ability of an organism to resist a particular infection

Innate Immunity = The immune protection a person is born with; immunity that is non-specific to a particular pathogen Adaptive Immunity = Immunity that develops after a person is infected with a specific pathogen; the body "remembers" how to fight that pathogen again Lymph = Milky fluid that carries immune cells through the lymphatic system White Blood Cell = Immune system cells that circulate in the blood to help fight infection

Antigen = A foreign substance which induces an immune response in the body Antibody = A protein produced by the body's immune system when it detects antigens; helps defend against these antigens Pathogen = Organism that can cause disease Bacteria = A type of living unicellular microorganism, some can cause disease
