The Lymphatic System.

Front 1

Is simply the name given to tissue fluid that has entered the dead-end lymph capillaries found in tissue spaces:

Back 1

Lymph

Front 2

Encapsulated masses of lymphatic tissue found along the pathways of the larger lymph vessels, and lymph flows through them on its way back to the blood:

Back 2

Lymph nodes

Front 3

Are unencapsulated masses of lymphatic tissue found just beneath the epithelium of all mucous membranes:

Back 3

Lymph nodules

Front 4

Tissue fluid is made from:

Back 4

Blood plasma

Front 5

Lymph vessels from the lower body unite to form the ________ _____ (in front of the second lumbar vertebrae), which continues upward as the thoracic duct.

Back 5

Cisterna chyli

Front 6

Vessels from the upper left quadrant join the thoracic duct, and it empties lymph into the:

Back 6

Left subclavian vein

Front 7

The upper right quadrant of the body is drained of lymph by vessels that form the right lymphatic duct, which empties into the:

Back 7

Right subclavian vein

Front 8

The lymph capillaries of the villi of the small intestine are ________; they absorb fat-soluble end products of digestion.

Back 8

Lacteals

Front 9

The ________ tonsils are on either side of the oropharynx.

Back 9

Palatine

Front 10

The __________ tonsil (adenoid) is on the posterior wall of the nasopharynx.

Back 10

Pharyngeal

Front 11

The _______ tonsils are on the base of the tongue.

Back 11

Lingual

Front 12

Lymph nodules of the small intestine:

Back 12

Peyer's patches

Front 13

The ______ _____ is located in the mediastinum beneath the sternum; it is large during fetal development and childhood, but shrinks thereafter.

Back 13

Thymus gland

Front 14

RBC graveyard:

Back 14

Spleen

Front 15

______ immunity refers to nonspecific defense mechanisms that come into play immediately or within hours of an antigen's appearance in the body.

(These mechanisms include physical barriers such as skin, chemicals in the blood, and immune system cells that attack foreign cells in the body.)

Back 15

Innate

Front 16

________ immunity (acquired immunity) is very specific for each pathogen; its responses become more efficient with repeated exposures because it creates memory for pathogens.

Back 16

Adaptive

Front 17

____-________ immunity requires macrophages and helper T cells to recognize a foreign antigen. The activated T cell then divides many times to produce subsets: cytotoxic T cells and memory T cells.

Back 17

Cell-mediated

Front 18

Occurs upon recovery from a disease:

Back 18

Naturally acquired active immunity

Front 19

Involves transmission of antibodies from mother to fetus or infant, across placenta or in breast milk:

Back 19

Naturally acquired passive immunity

Front 20

Involves a vaccine that stimulates antibody production:

Back 20

Artificially acquired active immunity

Front 21

Involves injection of preformed antibodies after exposure to a pathogen:

Back 21

Artificially acquired passive immunity
