30. Larger than average RBCs are macrocytic (left), while those smaller than average are microcytic (right).

31. Pale cells (central pallor >1/3 dia) are referred to as hypochromic (right), while cells without central pallor are called hyperchromic (left).

46. With iron deficiency anemia, the MCV of the red blood cells is decreased, the zone of central pallor is increased, and the overall sizes and shapes of the RBC's are less uniform (increased anisocytosis and poikilocytosis ).

47. Heinz bodies (red arrows) and nucleated red blood cells (purple arrows) in scattered erythrocytes of a dog with zinc toxicosis (Dog, blood smear, Wright-Leishman stain).

48. Spherocytes (red arrows) and nucleated red blood cells (purple arrows) in the blood smear of a dog with zinc toxicosis (Dog, blood smear, Wright-Leishman stain).

53. Can you identify the segmented neutrophil, band neutrophil, lymphocyte, monocyte, eosinophil, basophil, and platelet in this image?

56. This is a picture of a blood smear as seen by a microscope
This is a picture of a blood smear as seen by a microscope.  The red cells are the smaller, more numerous round objects. There are two white cells in the middle (they are blue because they have been stained).

66. Picture of bone marrow smear (control); Normal granulocytes and erythroblasts are evident.

67. Acute lymphoid leukemia (ALL); There is a marked proliferation of small lymphoblasts.

68. Acute myeloid leukemia (AML); There is a marked proliferation of large myeloblasts
