Active immunity can be acquired through natural immunity or vaccine-induced immunity. The Immune System •Immune system provides resistance to disease •Made up of two intrinsic systems -Innate (nonspecific) defense system •Constitutes first and second lines of defense -First line of defense: external body membranes (skin and mucosae) -Second line of defense: antimicrobial proteins, phagocytes, and other cells (inhibit spread of invaders; The immune system is the body's defense mechanism that protects the body from invasive bacteria, viruses, and pathogens.
