Plasma protein that helps the osmotic concentration of the blood.

Term

 

 

antibody (234)

 

 

Definition

 

Protein (Y-shaped) produced in response to the presence of some foreign substance in the blood or tissues; made by B-lymphocytes (plasma cells).

Term

antigen (234)

Definition

 

Foreign substance, usually a protein, that stimulates the immune system to produce antibodies.

Term

Chemicals which result from the breakdown of the heme portion of erythrocytes in the liver.

Term

 

 

cerebrovascular accident(CVA) (236)

Definition

 

Condition resulting when an arteriole in the brain bursts or becomes blocked by an embolism; stroke.

Term

 

 

coagulation (236)

Definition

 

 

 The final stage of hemostasis; the clotting of the blood using 13 different protein clotting factors which result in the formation of a fibrin mesh.

Term

edema (238)

Definition

 

Swelling due to tissue fluid accumulation in the intercellular spaces.

Term

 

 

eosinophil (232)

 

 

Definition

 

 

Granular leukocyte capable of being stained with the dye eosin; breakdown of antigen-antibody complexes.

Term

 

erythrocyte (230)

Definition

 

Non-nucleated, hemoglobin containing blood cell capable of carrying oxygen; red-blood cell.

Term

 

erythropoietin (epo)

(230)

Definition

 

Kidney hormone which promotes red blood cell formation.

Term

 

fibrin (236)

Definition

 

 

Insoluble protein threads formed from fibrinogen during blood clotting (coagulation).

Term

fibrinogen (236)

Definition

 

 

Plasma protein that is converted into fibrin threads during coagulation.

Term

formed element (228)

Definition

 

 

Cellular constituent of blood.

Term

 

globulin (228)

Definition

 

 

Type of protein in blood plasma; there are alpha, beta, & gamma globulins.

Term

 

granular leukocyte

(232)

(230)

Definition

 

 

Production of all blood cells.

Term

hemoglobin (230)

Definition

 

 

Pigment of red blood cells responsible for oxygen transport.

Term

 

hemolysis (232)

Definition

 

 

Bursting of red blood cells with release of hemoglobin; can be caused by osmotic conditions.

Term

hemostasis (234)

Definition

 

 

Stoppage of bleeding caused by vasoconstriction, platelet plug formation & coagulation.

Term

 

 

leukocytes (232)

 

 

Definition

 

Several types of colorless, nucleated blood cells that among other functions, resist infection; white blood cells.

Term

 

 

lipoproteins (230)

Definition

 

Lipids in which the alpha and beta globulins bind to in order to transport cholesterol in the blood.

Term

 

lymph (238)

Definition

 

Fluid having the same composition as tissue fluid; carried in the lymphatic vessels.

Term

 

 

lymphatic vessel

(238)

Definition

 

 

Vessel that carries lymph.

Term

 

 

lymphocyte

(234)

Definition

 

Agranular leukocyte, large spherical nucleus that takes up most of the cell; specific immunity,  destroying cancer cells.

Term

 

macrophage (234)

Definition

 

 

Enlarged monocyte that ingests foreign material and cellular debris.

Term

 

 

megakaryocyte (234)

Definition

 

 

Large bone marrow cells that give rise to platelets.

Term

 

monocyte (234)

Definition

 

 

Agranular type of white blood cell that acts as a phagocyte.

Term

 

multipotent stem cell

(230)

Definition

 

 

Red bone marrow cells that may differentiate into all various types of blood cells; hemocytoblast

Term

 

neutrophil (232)
