It was just a few weeks ago when...
Pathogen- organisms that cause disease
Antigen- protein markers on cells
Antibody- proteins made in response to antigens (When an antigen is detected, several types of cells work together to recognize and respond to it. These cells trigger the B lymphocytes to produce antibodies.)
Immune response- reaction of cells and fluids of the body to the presence of a substance that's not recognized as a part of the body
Phagocyte- a type of cell within the body capable of engulfing and absorbing bacteria and other small cells and particles
