Immunity Flashcards
what type of immunity is the following:
developed after birth as a result of a disease or vaccination/immunization
acquired immunity
what type of immunity is the following:
we are born with some important immune defenses, which our body obtained due to genetic makeup. For example, skin, gastric juice, lymphatic system, specific markers on our blood cells and all other cells (antigens) represent such an innate immunity.
innate (natural) immunity
what type of immunity is the following:
recognition and differentiation of self versus non self based on specific cellular markers
specific immunity
which type of immunity is the following:
does not require specific markers for actions
non-specific immunity
which type of immunity is the following
liquid form of immune defense, represented by B lymphocytes and their manufactured anti-bodies (immuno-globulins)
humoral immunity
which type of immunity is the following:
represented by T lymphocytes
cellular immunity
which type of immunity is the following
pre-formed defense “tools” and administered to a human as anti-bodies, produced in another biological organism or human organism
passive immunity
what type of immunity is the following:
produced by the body’s immune system itself, as a response to infection or vaccination
active immunity
organs of the immune system
lymphoid organs are concerned with the growth, development, and deployment of lymphocytes-WBCs that are key operatives of the immune system: tonsils adenoids thymus lymph nodes spleen appendix lymphatic vessels bone marrow
cells of the immune system
arise in the bone marrow from stem cells
some develop into myeloid cells:
-particle-devouring WBCs: (phagocytes [monocytes, macrophages, and neutrophils])
-inflammatory cells: eosinophils and basophils
non-specific cells
neutrophils, macrophages, monocytes, mast cells, basophils and eosinophils
(white blood cells which are “scavengers”
specific cells:
lymphocytes - need markers in order to attack
consist of B and T lymphocytes
what is the difference between B and T lymphocytes
B Lymphocytes - secrete globulins; they represent humoral immunity
T Lymphocytes - clusters of differentiation (markers); represent cellular immunity because they accomplish their job within tissues - not blood like humoral immunity
what are the subpopulations of B and T lymphocytes
B lymphocytes:
plasma cells; include immunoglobulins that assist the sanitation department in taking care of foreign material; have “forks” that attach to non-specific cells to do their job
