Chapter 6-Blood And Lymphatic Systems Flashcards
Anticoagulant
A drug that prevents clotting of the blood
Autologous blood
Blood donated and stored for a patient for future use
Autoimmune disease
Abnormal function of the immune system that causes the body to produce antibodies against itself
Anemia
Reduced number of red blood cells, hemoglobin, resulting in the inability for red blood cells to transport oxygen
Acquired immunodeficiency syndrome (AIDS)
Caused by HIV, that causes immune cells to be ineffective
Blast/o, -blast
Germ or bud
Active immunity
Long lasting immunity that results from the stimulating the body to produce it’s own antibodies
Antibody
Substance produced by the body that destroys an antigen that has entered the body
Chrom/o, chromat/o
Color
Blood component therapy
Transfusion of a specific blood component (blood cells, platelets )
Cross matching
Method of matching a donors blood to the recipient
Antigen
A substance that when is introduced to the body, causes the formation of antibodies against it
Chyl/o
Juice
Hemoglobin
Protein-iron compound in erythrocytes that transports oxygen and carbon dioxide
Hemostatic
A drug that stops the flow of blood within the vessels
Hem/o, hemat/o
Blood
Erythropenia
Abnormally reduced number of red blood cells
Erythrocyte
Red blood cell
Homologous blood
Blood voluntarily donated by any person for someone in need of it
Immun/o
Safe
Hemolysis
Breakdown of the red blood cell membrane
Immunosuppression
Impaired ability to provide an immune response
Lymph/o
Clear fluid
Immunocompromised
Impaired immunologic defenses
Leukocyte
White blood cells
Immunity
Process of a disease protection include by exposure to an antigen
Lymphadenectomy
Removal of a lymph node
Lymphadenotomy
Incision into a lymph node
Morph/o
Form
Lymph
Fluid that is circulated through the lymph vessels
Phag/o
Eat or sallow
Lymph nodes
Small, oval structures that filter lymph from lymph vessels
Lymph ducts
Collecting channels that carry lymph from the lymph nodes to the veins
Leukemia
Chronic disease of the blood forming organs
Lymphoma
Any neoplastic disorder of the lymph tissue
Lymphadenopathy
Enlarged lymph nodes
Metastasis
Cancer cells are spread to blood or lymph circulation
Plas/o
Formation
Plasma
Liquid portion of the blood and lymph
Lymph capillaries
Microscopic vessels that draw lymph from tissues to the lymph vessels
Platelets
Thrombocytes (cell fragments in the blood that at essential for blood clotting)
Reticul/o
A net
Passive immunity
Short lasting immunity that results from the foreign antibodies that are conveyed
Pancytopenia
Abnormally reduced number of all cellular components in the blood
Serum
Liquid portion of the blood that remains after clotting
Rh factor
Lack of antigens on the surface of red blood cells, causing a reaction between rh +/-
Rh negative
Absence of antigens
Rh positive
Presence of antigens
Splen/o
Spleen
Spleen
Organ between the stomach and the diaphragm that filters out aging blood cells
Splenomegaly
Enlargement of the spleen
Thromb/o
Clot
Splenectomy
Removal of a spleen
Thym/o
Thymus gland
Thymus
Primary gland of the lymphatic system, located within the mediastinum, that helps maintain the body’s immune response
Thymectomy
Removal of the thymus gland
Phlebotomy / venipuncture
Incision into or puncture of a vein to withdraw blood for testing
Vasoconstrictor
A drug that causes narrowing of blood vessels (decreased blood flow)
Vasodilator
A drug that causes dilation of blood vessels, increasing blood flow
