formation of clumps

leukocytes that do have granules within the cytoplasm, include lymphocytes & monocytes

• in blood transfusion
• sensitivity to donor plasma proteins.
• infusion of IgA proteins to IgA-deficient recipient who has developed IgA antibody

• Reversion of cells to an immature or a less differentiated form, as occurs in most malignant tumors.
•  

reduction below normal of the number of erythrocytes, quantity of hemoglobin, or the volume of packed red cells in the blood

any substance capable of inducing a specific immune response and of reacting with the products of that response

a drug or other substance that is an antagonist to or resembles a normal human metabolite and interferes with its function in the body, usually by competing for its receptors or enzymes

a disease in which the pt has peripheral blood pancytopenia (decrease of all blood cell types-RBCs, WBCs, & platelets) & hypocellular bone marrow

invasion of bloodstream by bacteria

blood cells in early stage of development

not malignant, favorable for recovery

any substances that cause cancer

malignant epithelial tumor

an abnormal closed epithelium-lined cavity in the body, containing liquid or semisolid material.

the study of cells, their origin, structure, function, and pathology.

disseminated intravascular coagulation

the spread of pernicious process

alteration in size, shape, and organization of adult cells

a hemorrhagic spot, larger than a petechia, in the skin or mucous membrane, forming a flat, rounded or irregular, blue or purplish patch.

The escape of fluid from the blood vessels or lymphatics into the tissues or a cavity

produced, orginated within an organism, tissue, cell

nose bleeding

RBCs

a deficiency or decrease in number of erythrocytes.

formation or production of RBCs

inflammation of the tongue

leukocytes that have granules within the cytoplasm

the percentage of total blood volume occupied by RBCs

the oxygen-carrying protein, give the red color of the RBCs

destruction of RBCs by monocytes & macrophages removes abnormal, defective, damaged, & old RBCs from circulation

a sequence of responses to stop blood loss from a damaged blood vessel. Three mechanisms are involved: vascular spasm, platelet plug formation, and blood clotting.

study of minute structure of tissues and organs in relation to their function.

reduction of the number of leukocytes in the blood below about 5000/uL

the film produced by lymphangiography

a kind of agranulocytes, major combatants in immune responses

a vague feeling of discomfort

a type of agranulocytes, take longer to reach a site of infection than do neutrophils, but they arrive in large numbers. Upon their arrival, monocytes enlarge and differentiate into wandering macrophages, which phagocytize many more microbes than can neutrophils. They also clean up cellular debris following an infection.

The lowest value of blood counts after chemotherapy.

tumor; any new and abnormal growth, specifically one in which cell multiplication is uncontrolled and progressive. Neoplasms may be benign or malignant.

a type of WBCs, active in phagocytosis, respond most quickly to tissue destruction by bacteria. After engulfing a pathogen during phagocytosis, a neutrophil unleashes several destructive chemicals to destroy the ingested pathogen.

not visible, or easily detected

A gene that causes the transformation of normal cells into cancerous tumor cells, especially a viral gene that transforms a host cell into a tumor cell.

formation, production of tumors

the study of tumors

paleness of the skin

a marked reduction of RBCs, WBCs, platelets in the blood

the watery straw-colored fluid part of the lymph and the blood in which the leukocytes, erythrocytes, and platelets are suspended

are thrombocytes, initiate the clotting process by producing an initial platelet plug in the early phases of clotting process

A large, purplish-red circle on the skin. Caused by the leakage of blood out of a vessel and under the skin. medium size, larger than pinpoint petechiae but smaller than ecchymosis

abbreviation for radiation absorbed dose.

energy transmitted by waves through space or through some medium; usually referring to electromagnetic radiation, when used without a modifier

an immature erythrocyte

use of protective equipment is required to prevent transmission of infection to the patient. Handwashing, gowning, gloving, sterilization, or disinfection of materials brought into the area and other details of housekeeping vary with the reason for the isolation and the usual practices of the hospital.

blood poisoning; systemic disease associated with the presence and persistence of pathogenic microorganisms or their toxins in the blood

Inflammation of the mucous lining of any of the structures in the mouth, which may involve the cheeks, gums, tongue, lips, and roof or floor of the mouth

another name for platelets

a reduction of platelets below 150,00/uL
