Clumping of recipient's blood cells when incompatible bloods are mixed.
Protein found in blood; maintains the proper amount of water in the blood. Also called serum albumin.
Protein substances whose formation by lymphocytes is stimulated by the presence of antigens in the body. An antibody then helps to neutralise or inactivate the antigen that stimulated its formation.
Foreign materials that stimulate the production of an antibody. Naturally occurring antigens are the blood type factors A and B that are present at birth in some individuals.
White blood cell with large, dark, basic-staining granules.
Orange-yellow pigment produced from haemoglobin when red blood cells are destroyed. Bilirubin is concentrated in bile by the liver and excreted in the faeces.
The process of blood clotting
Proteins that stimulate the growth and proliferation of white blood cells (granulocytes).
Little body; refers to a blood cell.
Change in structure and function of a cell as it matures; specialisation.
Method of separating substances (such as proteins) by electrical charge.
White blood cell with dense, reddish granules; associated with allergic reactions.
A red blood cell. There are about 5 million in a speck of blood the size of a pinhead.
A hormone secreted by the kidney that stimulates bone marrow to make red blood cells.
Protein threads that form the basis of a blood clot.
Plasma protein that is converted to fibrin in the clotting process.
The cellular elements in blood.
The protein part of haemoglobin.
Plasma protein is separated by electrophoresis into alpha, beta and gamma globulins.
White blood cells with granules: eosinophils, neutrophils and basophils.
Iron-containing no-protein portion of the haemoglobin molecule.
Blood protein found in red blood cells; carries oxygen.
An anticoagulant produced by liver cells and found in blood and tissues.
Process by which an antibody neutralises or inactivates an antigen.
A protein (globulin) with antibody activity; examples are IgG, IgM, IgA, IgE, IgD, Immun/o means protection.
A white blood cell.
White blood cell (agranulocyte) that produces antibodies.
Monocytes that have migrated from the blood to tissue spaces. They are large phagocytes that destroy red blood cells at the end of their 120-day life span. They also engulf foreign material in body tissues.
Platelet precursor formed in the bone marrow.
A phagocytic white blood cell (agranulocyte) formed in bone marrow. Monocytes become macrophages as they leave the blood and enter body tissues.
Derived from (-oid) bone marrow cells.
White blood cell (granulocyte) formed in bone marrow; a phagocyte with neutral-staining granules; also called a polymorphonuclear leukocyte.
Liquid portion of blood; contains water, proteins, salts, nutrients, hormones and vitamins.
Process of using a centrifuge to separate (-apheresis) or remove the formed elements from the blood plasma. Formed elements are retransfused into the donor and fresh-frozen plasma is used to replace withdrawn plasma. The procedure may be done to collect plasma for analysis or therapy.
Smallest formed element in the blood; a thrombocyte.
Plasma protein; converted to thrombin in the clotting process.
Developing red blood cell with a network of granules in its cytoplasm.
An antigen normally found on red blood cells of Rh-poistive individuals.
Plasma minus clotting proteins and cells.
A cell in bone marrow that gives rise to different types of blood cells.
Enzyme that helps convert fibrinogen to fibrin during coagulation.
A clotting factor that, in combination with calcium, promotes the formation of the fibrin clot.
