Flashcards in Lymph Heart Deck (100):
Extreme form of allergic response in which the patient suffers severely decreased blood pressure and constriction of the airways.
Syndrome cause by human immunodeficiency virus (HIV) and transmitted through body fluids via sexual contact or intravenous exposure. HIV attacks the helper T cells, which diminish the immune response
Immune system’s overreaction to irritants that are perceived as antigens. The substance that causes the irritation is called an allergen. Also called hypersensitivity.
A decrease in red blood cells, hemoglobin, and/or hematocrit
a condition in which the body produces an immune response against its own tissue constituents
Blood samples are submitted to propagate microorganisms that may be present. Cultures may be indicated for bacteremia or septicemia, or to discover other pathogens
Intravenous transfer of blood from a donor to a recipient, giving either whole blood or its components
The transplant of bone marrow to stimulate production of normal blood cells
Bone marrow transplant (BMT)
Twelve tests, including RBC, WBC, hemoglobin (Hb), hematocrit/packed cell volume (Hct/PCV), and diff (WBC differential.
Complete blood count (CBC)
Bad mixture. Used to describe diseases of the blood or bone marrow
Measure of the percentage of red blood cells (RBCs) in the blood
Measure of iron-containing pigment of red blood cells (RBCs) that carries oxygen to tissues
Hemoglobin (Hgb) or (Hb)
Breaking down of blood
Attraction condition of blood. Group of inherited bleeding disorders characterized by a deficiency of one of the factors necessary for the coagulation of blood. Blood does not clot normally.
Rapid loss of blood, usually due to a ruptured blood vessel
The control of bleeding by mechanical or chemical means
Deficient volume of circulating blood
A type of blood cancer that begins in the bone marrow. Bone marrow is where cells are produced (i.e white blood cells)
Abnormal increase in white blood cells (WBCs).
Disease of the lymph nodes or vessels that may be localized or generalized
Radiographic visualization of a part of the lymphatic system after injection with a radiopaque substance.
Accumulation of lymphatic fluid and resultant swelling caused by obstruction, removal, or hypoplasia of lymph vessels
Increase in the number of mononuclear cells (monocytes and lymphocytes) in the blood caused by the Epstein-Barr virus (EBV). Can result in splenomegaly, enlarged spleen.
Deficiency of all blood cells caused by dysfunctional stem cells
Process in which the liquid in the blood, or plasma, is separated from the cells
Bleeding disorder characterized by hemorrhage into the tissues
Removal of the spleen
Deficiency of platelets that causes an inability of the blood to clot. The most common cause of bleeding disorders.
The ways that the body has acquired antibodies to specific diseases (Can be active passive, natural, or artificial)
When blood cells clump together as a result of escaping their normal vessels.
The antibody to agglutinogen
In blood, antigens are called agglutinogens because their presence can cause the blood to clump
The body produces antibodies that nullify, or neutralize, the antigens
Substances that produce an immune reaction by their nature of being perceived as foreign to the body
Use a process called humoral immunity (aka antibody-mediated immunity). They secrete antibodies to “poison” their enemies.
Combat parasites and release histamine and heparin which heal damaged tissue. Absorb basic dye and stain a bluish color. Type of granulocyte.
Transports gases, chemical substances, and cells that defend the body. Regulates the body’s fluid and electrolyte balance, acid-base balance, and regulates temperature. Protects the body from infection. Protection of the body from loss of blood by the action of clotting
The process of changing a liquid to a solid
Chemical messengers secreted by cells of the immune system that direct immune cellular interactions
Cells that absorb an acidic dye, which causes them to appear reddish. Defend body against allergens and parasites. Type of granulocyte.
Red Blood Cells (RBCs)
Process of blood formation
A protein-iron pigment that helps transport O2 and CO2 throughout the body. Red blood cells carry O2 and CO2.
Control of blood flow; that is, stopping the bleeding
A “steady state.” A continual balancing act of the body systems to provide an internal environment that is compatible with life
Resistance of an organism to infectious diseases
A type of cytokine that sends messages among leukocytes to direct productive action
White blood cells (WBCs)
Fluid that circulates through the lymphatic system
Also known as lymph glands, filter the debris produced by macrophages. Can become enlarged when pathogens are present.
Carry lymph via valves (one-way vessels)
Aka phagocytes because they specialize in phagocytosis. Combat bacteria in pyogenic infections. Consume and remove debris. Do not absorb acidic or basic die, so they are purple in color. Type of granulocyte.
Liquid portion of blood
White blood cells that have small grains within the cytoplasm and multibodied nuclei
An antigen important in pregnancy. A mismatch between the fetus and the mother can cause erythroblastosis fetalis.
Plasma minus the clotting proteins
Organ in the lymphatic system. Located in the upper left quadrant of the abdomen and serves to filter, store and produce blood cells; remove RBCs; and activate B lymphocytes.
All blood cells originate from a single
type of cell called a stem cell
Neutralize enemies through cell-mediated immunity. They attack antigens directly. They are effective against fungi, cancer cells, protozoa, and organ transplants
Also called clotting cells, cell fragments, or platelets
The thymus gland is located in the mediastinum and develops T lymphocytes (T cells)
Lymphatic tissue that helps protect the entrance to the respiratory and digestive systems. An organ in the lymphatic system.
Lymph gland (node)
abnormal increase in cells
