Anatomy and Physiology Blood
Plasma - -clear, straw-colored liquid portion of blood



Albumin - -plasma protein that helps regulate osmotic concentration



Globulins - -plasma proteins synthesized by liver; used for transport of gases, lipids,
and fat-soluble vitamins; hemoglobin is an example



Hematocrit - -percentage of red blood cells in blood



Hematopoietic stem cells - -give rise to all blood cells; found in bone marrow (aka
hemocytoblasts)



Megakaryocyte - -cells that develop from stem cells to become thrombocytes



Erythrocyte - -mature red blood cell



Hemoglobin - -oxygen-carrying molecule found on erythrocyte; contains iron



Erythropoiesis - -production of red blood cells



Erythroblast - -immature red blood cell



Anemia - -deficiency of red blood cells

, Oxyhemoglobin - -hemoglobin carrying oxygen-bright red in color



Deoxyhemoglobin - -hemoglobin with no oxygen



Leukocyte - -white blood cell



Diapedesis - -squeezing of leukocytes through blood vessel wall



Neutrophil - -phagocytic white blood cell; first responders to site of infection
(bacteria, virus, & some fungi)



Basophil - -type of white blood cell active during allergic response; produces
histamine and promotes inflammation



Eosinophil - -type of white blood cell; causes allergy response



Monocyte - -largest white blood cell; become macrophages; phagocytize bacteria,
dead cells, and other intercellular debris



Lymphocyte - -type of white blood cell that directly attack specific microorganisms,
tumor cells, & transplanted cells (B & T cells)



Phagocytosis - -cell eating



Intracellular - -within a cell
