(230)

Kidney hormone which promotes red blood cell formation.

(232)

White blood cell with prominent granules in the cytoplasm; Basophils, Eosinophils, & Neutrophils.

hematocrit (228)

The % of blood attributed to the formed elements.

hematopoiesis

(230)

Production of all blood cells.

hemoglobin (230)

Pigment of red blood cells responsible for oxygen transport.

hemolysis (232)

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

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

leukocytes (232)

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

(238)

Vessel that carries lymph.

lymphocyte

(234)

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

macrophage (234)

Enlarged monocyte that ingests foreign material and cellular debris.

megakaryocyte (234)

Large bone marrow cells that give rise to platelets.

monocyte (234)

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

multipotent stem cell

(230)

platelet (234)

Also called a thrombocyte, these cell-like disks are formed from fragmentation of megakaryocytes; they function in the initiation of blood clotting.

prothrombin (236)

Plasma protein (factor II) made in the liver that must be present in blood before clotting can occur.

prothrombin activator

(236)

Enzyme that catalyzes the transformation of the precursor prothrombin to the active enzyme thrombin.

thrombin (236)

Enzyme derived from prothrombin that converts fibrinogen to fibrin threads during blood clotting.

Basophil

eosinophil
