Lymphatic/Immune/Oncology Medical Terminology

These flashcards cover essential medical terminology related to the lymphatic system, immune responses, and oncology as outlined in the lecture notes.

anaphylaxis

Severe, potentially life-threatening allergic reaction.

antihistamine

A drug that blocks the effects the efforts of histamines, which are chemicals in the body that produce symptoms of allergic reaction

aplastic anemia

Disorder in which the bone marrow does not produce enough new red blood cells (RBCs), white blood cells (WBCs), and platelets

B lymphocytes (B cells)

Lymphocytes that transform into plasma cells in response to an

antigen and then secrete immunoglobulins

blast

A large, immature cell that matures into a blood cell. An immune response that involves T lymphocytes, cell-mediated immunity

eosinophils

Granulocytes that secrete chemicals to attack disease-causing parasites and respond during an allergic reaction

immunity

the ability to resist pathogens and toxins that cause infection or disease

immunotherapy

Treatment of a disease by stimulating or inhibiting the body’s immune response.

inflammatory response

A naturally occurring process that the body undergoes in response to injury or invasion

leukocytes

White blood cells.

lymph nodes

Small, bean-shaped structures that are located throughout the body and which filter foreign substances from the lymph before it is returned to the blood

lymphoma

Malignant cancer of the lymph nodes and lymphatic tissue.

megakaryocytes

bone marrow cells with very large nuclei

monocytes

large, single-nucleus phagocytes that ingest and dispose of dead or dying cells and tissues

myeloma

Cancer of the blood in which plasma cells grow uncontrollably in the bone marrow

neutrophils

Cells that destroy harmful pathogens

T lymphocytes (T cells)

Lymphocytes that are made in the bone marrow but mature in the thymus, and which play a key role in the immune response

spleen

The largest lymphatic organ in the body; filters the blood, produces lymphocytes, stores thrombocytes, and serves as a reservoir for blood.

NOSOCOMIAL

An infection acquired in a hospital setting that was not present upon admission.

B lymphocytes (B cells)

Lymphocytes that transform into plasma cells in response to an antigen and then secrete immunoglobulins.

thrombus

A blood clot that forms on the wall of a blood vessel and stays attached to the site in which it developed.

antihistamine

A drug that blocks the effects of histamines, which are chemicals in the body that produce symptoms of allergic reactions.
