Immune System Basics

Specific Immunity

• The immune system's targeted response to a specific pathogen.

• A general defense mechanism against all pathogens.

• The body's first line of defense against infections.

• An automatic response to any foreign substance.

Nonspecific Immunity

• The first line of defense against pathogens, providing general protection.

• A targeted response to specific pathogens.

• The body's ability to remember past infections.

• A type of immunity that develops after vaccination.

Antibody

• A type of white blood cell that fights infections.

• A protein produced by B cells that recognizes and neutralizes pathogens.

• A carbohydrate that provides energy to cells.

• A lipid that helps in cell membrane formation.

B Cell

• A type of lymphocyte that produces antibodies to fight infections.

• A type of red blood cell that carries oxygen.

• A type of white blood cell that helps in blood clotting.

• A type of cell that stores fat in the body.

Antigen

• A substance that triggers an immune response, often a part of a pathogen.

• A type of white blood cell that fights infections.

• A vaccine that prevents diseases.

• A chemical that inhibits immune response.

Memory Cell

• A type of cell that stores energy for the body.

• A long-lived immune cell that remembers past infections and responds quickly upon re-exposure.

• A cell that helps in the production of hormones.

• A cell that is responsible for muscle contraction.

T Cell

• A type of lymphocyte that plays a central role in cell-mediated immunity.

• A type of red blood cell responsible for oxygen transport.

• A type of white blood cell that produces antibodies.

• A type of platelet involved in blood clotting.

Immunity

• The ability of the body to resist a particular infection or toxin.

• The process of digesting food in the stomach.

• The mechanism by which the body absorbs nutrients from food.
