Document Summary
Hematocrit: the percentage of total blood volume occupied by erythrocytes. Plasma: the nonliving fluid component of blood within which formed elements and various solutes are suspended and circulated. Erythrocytes (red blood cells, rbcs): red blood cells. Heme: iron-containing pigment that is essential to oxygen transport by hemoglobin. Hematopoietic stem cell: bone marrow cell that gives rise to all the formed elements of blood; hemocytoblast. Erythropoietin (epo): hormone that stimulates production of red blood cells. Anemia: reduced oxygen-carrying ability of blood resulting from two few erythrocytes or abnormal hemoglobin. Intrinsic factor: substance produced by the stomach that is required for vitamin b12 absorption. Leukocytes (white blood cells, wbcs): white blood cells; formed elements involved in body protection that take part in inflammatory and immune responses. Diapedesis: passage of white blood cells through intact vessel walls into tissue. Amoeboid motion: the flowing movement of the cytoplasm of a phagocyte.
