Cell Types Flashcards
erythrocytes
red blood cells, made in the bone marrow, they carry oxygen from the lungs through the blood and deliver it to all body cells
hemoglobin
an important protein in an erythrocyte, carries oxygen through the bloodstream
leukocytes
white blood cell, 5 different leukocytes
granulocytes
contains dark staining granules in their cytoplasm, 3 different types of granulocytes
eosinophils
a granulocyte, their granules stain red with an acidic stain, increased in number in allergic reactions
basophils
a granulocyte, their granules stain blue with a basic stain, their purpose is not clear, but they increase during the healing phase of inflammation
neutrophils (polymorphonuclear leukocytes-polys)
a granulocyte, their granules stain a pale purple with a neutral stain, they are the most important disease fighting cells and are the most numerous
mononuclear cells
have 1 large nucleus and have only a few granules in their cytoplasm. They are produced in the bones marrow, spleen, and lymph nodes. There are 2 types.
lymphocytes
a mononuclear cell, they fight disease by producing antibodies, destroying foreign cells. 2 types of lymphocytes T and B cells.
monocytes
a mononuclear cell, engulf a destroy cellular debris after neutrophils have attacked.
phagocytes
are neutrophils that engulf and digest bacteria like pac-men.
macropahges
monocytes leave the bloodstream and enter tissue (liver and lungs) to become macrophages, largest phagocytes
thrombocytes or plattlets
clotting cells, the 3rd type of blood cell, tiny fragments of cells formed in the bones marrow and are necessary for clotting.
