Blood Cells & Blood VesselHistology Blood Cells: Page 324 Blood Vessel Histology: Page 284
Blood Cell Histology • I will use the diagrams similar to the ones on page 324 to test you on blood cells. • Be able to identify: • Erythrocytes (red blood cells) • Neutrophil • Lymphocyte • Monocyte • Eosinophil • Basophil
LymphocytesSmall (about same size as the RBC’s) with a round nucleus that fills up most of the cell
EosinophilsCytoplasm is more pinkish in color, VERY granular, sometimes have a “snowman” nucleus
BasophilIf you are getting them confused with lymphocytes, note the SIZE. Basophils are LARGER than RBC’s whereas lymphocytes are the same size as RBC’s.
