Final ReviewVersion AChapter 19: The Cardiovascular System: The BloodBuffy Coat: The fraction of an anticoagulated blood sample that contains most of the WBCs and platelets. (Page 662)Plasma Pro... teins: Proteins confined to blood; include: albumins, globulin, and fibrinogen. (Page 664)White blood cells (WBCs) or leukocytes protect the body from invading pathogens and other foreign substances. There are several types of WBCs. Each type of WBC contributes in its own way to the body's defense mechanisms. (Page 664)oMajor Function : Combat pathogens and other foreign substances that enter the body. (Page 675)Hemopoiesis: The process by which the formed elements of blood develop; occurs in redbone marrow. (Page 665)Thrombopoietin (TPO): A hormone produced by the liver that stimulates the formation of platelets from megakaryocytes. (Page 667)oMegakaryoblasts : Precursor cells that transform into megakaryocytes (Page 674)Major Histocompatibility (MHC) Antigen: Surface proteins on white blood cells and other nucleated cells that are unique for each person (except for identical siblings); used to type tissues and help prevent rejection of transplanted tissues. Also known as human leukocyte antigens (HLA). (Page 672)What cell secretes lysozyme? Neutrophils (Page 673)Major function of erythrocytes: Hemoglobin within RBCs transports most oxygen and part of carbon dioxide in the blood. (Page 675) Extrinsic Pathway: Occurs rapidly; tissue factor (TF) leaking into the blood from cells outside blood vessels and initiates the formation of prothrombinase. Prothrombinase converts prothrombin into the enzyme thrombin. Thrombin converts soluble fibrinogen into insoluble fibrin; fibrin forms the threads of the clot. (Page 678)Difference between thrombus and embolus (Page 680)oThrombus : A clot formed in an unbroken vesse [Show More]
