Medical Vocabulary: Hematology, Lymphatics, Pharmacology, and Immune Disorders

Vocabulary flashcards covering diagnostic procedures, medical and surgical procedures, pharmacology, sickle cell anemia, and systemic lupus erythematosus based on the lecture notes.

multiple myeloma

Malignant disease of bone marrow plasma cells (antibody-producing B lymphocytes)

opportunistic infection

Any infection that results from a defective immune system that cannot defend against pathogens normally found in the environment

bone marrow aspiration

Removal of a small amount of tissue (bone marrow biopsy) to diagnose blood disorders (e.g., anemias), cancers, or infectious diseases or to gather cells for later infusion into a patient (bone marrow transplantation)

complete blood count (CBC)

Series of blood tests to determine general health status as well as screening for infection, anemias, and other diseases; also called CBC

enzyme-linked immunosorbent assay (ELISA)

Test to screen blood for presence of HIV antibodies or for other disease-causing substances

lymphangiography

Radiographic examination of lymph glands and lymphatic vessels after an injection of a contrast medium to view the path of lymph flow as it moves into the chest region

tissue typing

Technique used to determine the histocompatibility of tissues; used to match donor grafts and transplants with the recipient's tissues and cells; also known as histocompatibility testing

Western blot

Test to detect presence of viral DNA in blood and used to confirm the diagnosis of AIDS as well as for detecting other viruses

blood transfusion

Administration of whole blood or a component, such as packed red blood cells (RBCs), to replace blood lost through trauma, surgery, or disease

bone marrow transplant

Diseased bone marrow is destroyed by irradiation and chemotherapy and replaced from a healthy donor to simulate production of normal blood cells; used to treat aplastic anemia, leukemia, and certain cancers

lymphangiectomy

Removal of a lymph vessel

anticoagulants

Prevent or delay blood coagulation

immunizations

Vaccination or injection of immune globulins to induce immunity to a particular infectious disease

immunosuppressants

Suppress the immune response to prevent organ rejection after transplantation or slow the progression of autoimmune disease

thrombolytics

Dissolve a blood clot

vaccinations

Introduction of altered antigens (viruses or bacteria) into the body to produce an immune response and protect against disease

sickle cell anemia

A hereditary form of anemia in which there is a deficiency of healthy red blood cells (RBCs) to carry adequate oxygen throughout the body, characterized by crescent- or sickle-shaped erythrocytes that become rigid and sticky, blocking blood flow

systemic lupus erythematosus (SLE)

An autoimmune disease characterized by unusual antibodies in blood that inflame and damage connective tissues anywhere in the body, typically resulting in a butterfly rash that appears on the face
