Immune System

Front 1

antigen and antibody

Back 1

a foreign molecule that evokes an immune response and a protein that recognizes antigens

Front 2

T and B cells

Back 2

mature in the thymus and carry out cell mediated immunity while B mature in the bone marrow and carry out humoral immunity

Front 3

humoral immunity and cell mediated immunity

Back 3

antibodies secreted by B cells carry out humoral immunity by producing antibodies to attack bacteria and viruses while in cell mediated immunity T cells attack body cells invaded by bacteria and viruses

Front 4

lymphatic system and circulatory system

Back 4

lymphatic consists of lymph vessels, lymph nodes, and other organs such as the thymus and spleen. It returns a fluid called lymph to the blood vessels and helps defend the body while the circulatory system consists of the heart, blood vessels, and blood

Front 5

active immunity and passive immunity

Back 5

active occurs when the body is stimulated by antigens and secretes antibodies in its defense while passive is when the body does not secrete antibodies but rather borrows antibodies temporarily

Front 6

blood and lymphatic capillaries

Back 6

both are narrow tubes with thin walls but blood capillaries are open at both ends whereas lymphatic capillaries end in dead ends.

Front 7

innate immunity and acquired immunity

Back 7

defenses such as skin, digestive juices and antimicrobial proteins (is nonspecific) while acquired immunity is carried out by the immune system and fully develops only after exposure to a specific pathogen

Front 8

neutrophils and macrophages

Back 8

neutrophils ingest, kill and digest bacterial cells into molecular bits while macrophages engulf and digest just about any foreign agent

Front 9

effector cells and memory cells

Back 9

effector cells are fully differentiated types that kill the enemy while others become memory cells which end up entering a reseting phase
