Abrielle's Human Blood Cells and Components Flashcards

Erythrocyte

A red blood cell

Leukocyte

White blood cells

Granulocyte

Leukocytes with granular cytoplasm

Agranulocyte

Leukocytes without cytoplasmic granules

Neutrophil

A granulocyte with fine cytoplasmic granules that stain light purple in neutral stain.

Eosinophil

A granulocyte that contains coarse, uniformly sized cytoplasmic granules that stain deep red in acid stain.

Basophil

A granulocyte similar to eosinophils in size and in the shape of their nuclei, but they have fewer, more irregularly shaped cytoplasmic granules that stain deep blue in basic stain.

Lymphocyte

An agranulocyte that is slightly larger than a red blood cell. They contain a large, round nucleus surrounded by a thin rim of cytoplasm.

Monocyte

An agranulocyte that is two to three times larger than a red blood cell. Their nuclei vary in shape and are round, kidney-shaped, oval, or lobed.

Platelets

Cytoplasmic fragment formed in bone marrow that helps blood clot.

Plasma

Fluid portion of circulating blood.

Formed Elements

Red blood cells, platelets, and white blood cells together

Blood Types

Blood types (A+, A-, B+, B-, AB+, AB-, O+, O-) are determined by inherited antigens and Rh factors

Granules

Small, enzyme-filled particles found within granulocytes

Nucleus

A cellular organelle enclosed by a double-layered, porous membrane and containing DNA. Used to identify the type of white blood cell.
