agglutin/o

Back 1

agglutinin
A substance, such as an antibody, that is capable of causing agglutination of a particular antigen, especially red blood cells or bacteria.

Front 2

cyst/o

Back 2

bladder, cyst

Front 3

Back 3

eosinophil:
any cell, tissue, organism, or substance that has an affinity for eosin and other acid stains

Front 4

eryth/o

Back 4

Red: erythroid

Front 5

hem/o

Back 5

blood

Front 6

antigen

Back 6

: any substance (as an immunogen or a hapten) foreign to the body that evokes an immune response either alone or after forming a complex with a larger molecule (as a protein) and that is capable of binding with a product (as an antibody or T cell) of the immune response

Front 7

basophils

Back 7

: a basophilic substance or structure ; especially : a white blood cell with basophilic granules that is similar in function to a mast cell

Front 8

coagulation

Back 8

1 a : a change to a viscous, jellylike, or solid state ; especially : a change from a liquid to a thickened curdlike state not by evaporation but by chemical reaction <the spontaneous coagulation of freshly drawn blood> <the coagulation of milk by rennin> b : the process by which such change of state takes place consisting of the alteration of a soluble substance (as a protein) into an insoluble form or of the flocculation or separation of colloidal or suspended matter

Front 9

erythrocyte

Back 9

red blood cell
any of the hemoglobin-containing cells that carry oxygen to the tissues and are responsible for the red color of vertebrate blood—called also erythrocyte, red blood corpuscle, red cell, red corpuscle;

Front 10

hematocrit

Back 10

an instrument for determining usually by centrifugation the relative amounts of plasma and corpuscles in blood
2 : the percent of the volume of whole blood that is composed of red blood cells as determined by separation of red blood cells from the plasma usually by centrifugation <a hematocrit ranging from 42% to 52% in males and 35% to 47% in females is typically considered normal>—called also packed cell volume

Front 11

hemaglobin

Back 11

an iron-containing respiratory pigment of vertebrate red blood cells that functions primarily in the transport of oxygen from the lungs to the tissues of the body, that consists of four polypeptide chains of which two are of the type designated alpha and two are of one of the types designated beta, gamma, or delta and each of which is linked to a heme molecule, that combines loosely and reversibly with oxygen in the lungs or gills to form oxyhemoglobin and with carbon dioxide in the tissues to form carbhemoglobin, that in humans is present normally in blood to the extent of 14 to 16 grams in 100 milliliters expressed sometimes on a scale of 0 to 100 with an average normal value (as 15 grams) taken as 100, and that is determined in blood either colorimetrically or by quantitative estimation of the iron present

Front 12

hemolysis

Back 12

lysis of red blood cells with liberation of hemoglobin

Front 13

hemostasis

Back 13

: stoppage or sluggishness of blood flow
2 : the arrest of bleeding (as by a hemostatic agent)

Front 14

hypersensitivity

Back 14

: excessively or abnormally sensitive
2 : abnormally susceptible physiologically to a specific agent (as a drug or antigen)

Function: noun
: an acute or chronic disease of unknown cause in humans and other warm-blooded animals that involves the blood-forming organs, is characterized by an abnormal increase in the number of white blood cells in the tissues of the body with or without a corresponding increase of those in the circulating blood, and is classified according to the type of white blood cell most prominently involved
