anisocytosis
condition characterized by a great inequality in the size of red blood cells
elliptocyte
oval red blood cells
elliptocytosis
condition characterized by an increase in the number of oval-shaped red blood cells
embolism
blockage in a blood vessel caused by an embolus
embolus
mass of matter present in the blood
erythrocyte
red blood cell
erythrocytosis
abnormal increase in the number of red blood cells
hematopoiesis
formation of blood cells
hemolysis
breakdown of blood cells
leukocyte
white blood cell
leukocytosis
increase in the number of white blood cells
leukopenia
deficiency in white blood cells (can be caused by an infection - if levels are too low, it may mean the patient has a weakened immune system (immunodeficiency))
macrocytosis
condition characterized by large red blood cells (causes for anemia include folate deficiency or B12 deficiency)
microcytosis
condition characterized by small, red blood cells (causes for anemia include iron deficiency and lead poisoning)
myelopoiesis
formation of bone marrow
neutropenia
deficiency in neutrophil (type of white blood cell)
normocyte
normal-sized red blood cell
oligocythemia
deficiency in the number of red blood cells
pancytopenia
deficiency in all cellular components of the blood
phagocytosis
process in which phagocytes (a type of white blood cell) destroy or eat foreign microorganisms or cell debris
poikilocytosis
condition characterized by red blood cells in a variety of shapes
polycythemia
excess of red blood cells
reticulcyte
immature red blood cells (the root comes from its netlike appearance)
spherocyte
red blood cell that assumes a spherical shape
