Chapter 5

agranulocytes category of white blood cells which do not have granules in their cytoplasm
neutrophils most numerous of the granulocytes; do not absorb stain or dye, and appear neutral in color

eosinophils type of white blood cell, helps to defend the body against an allergic reaction by increasing in number

agglutinate combine into a clump or mass
blood transfusion transfer of blood into a vein
donor the person who gives the blood
recipient the person who receives the blood, to prevent agglutination
cross-matching done in the laboratory; matches donor and receipt blood type
type A blood has A antigen on its surface but no A antibodies; does have in its plasma Anti-B antibodies
type B blood has B antigen on its surface and Anti-A antibodies in its plasma
type AB blood has AB antigen on its surface and no antibodies are present
type O blood has no antigens present; carries both Anti-A and Anti-B antibodies in its plasma
universal donor a person who has type O blood
universal recipient a person who has type AB blood
coagulation the clotting of blood
hemostasis the process by which the platelets, plasma, and coagulation factors interact to control bleeding from an injury
thrombus a clot that forms and lodges in an uninjured blood vessel
anemia deficiency in the quantity and or quality of the blood
dyscrasia abnormal condition of the blood or bone marrow
erythremia abnormal increase in the number of red blood cells
edema abnormal accumulation of fluid in the within the spaces of tissues
hemorrhage loss of a large amount of blood in a short period of time, either internally or externally
pancytopenia notable reduction in the number of red and white blood cells and platelets
septicemia systemic infection in which pathogens are present in the bloodstream, spreading an infection in any part of the body
splenomegaly abnormal enlargement of the spleen
thrombocytopenia abnormal condition where the number of platelets are reduced
leukemia excessive uncontrolled increased of immature white blood cells in the blood
immunity condition of being resistant to or protected from a disease
immunologist medical specialist who is involved in the study of disorders of the immune system
oncologist the medical specialist involved with the treatment of malignant tumors and cancers
lymph fluid (lymph) a clear, colorless fluid that contains a liquid protein
lymph capillaries smallest lymph vessel, collects and carries lymph fluid to larger vessels
lymphatic vessels moves fluid in one direction away from the tissues
lymphatic ducts larger lymph drainage vessels
left lymphatic ducts thoracic duct
right lymphatic ducts a vessel draining lymph from the cranial right side of the body, receiving lymph from the right subclavian, jugular and mediastinal trunks when those vessels do not open independently into the right brachiocephalic vein
lymph nodes any of the rounded masses of lymphoid tissue that are surrounded by a capsule of connective tissue, are distributed along the lymphatic vessels
phagocytes a cell (as a white blood cell) that engulfs and consumes foreign material (as microorganisms) and debris
macrophages functions in the destruction of foreign antigens (as bacteria and viruses
