What is the function of blood?
Transports oxygen, nutrients, and hormones to body cells and to carry away wastes.
What is the liquid portion of blood called?
What are the cellular components suspended in the plasma?

What is the lymphatic system consist of?
An intricate network of capillaries, vessels, valves, ducts, nodes and organs.
What is a function of the lymphatic system?
1. It protects the body by filtering microorganisms and foreign particles from the lymph and supporting the activites of the lymphocytes in the immune system.
What is another function of the lymphatic system?
It also serves to maintain the body's internal fluid environment by acting as an intermedicary between the blood in the capillaries and tissue cells.
What is the final function of the lymphatic system?
It is responsible for carrying fats away from the digestive organs.
primary gland of the lymphatic system that produces T lymphocytes (T cells)
filters out aging blood cells, removes cellular debris by performing phagocytosis, and provides the environment for the initiation of immune responses by lymphocytes.
fluid originating in the organs and tissues of the body that is circulated through the lymph vessels
microscopic vessels that draw lymph from the tissues to the lymph vessels
lymph capillaries
vessels that receive lymph from the lymph capillaries and circulate it to the lymph nodes
lymph vessels
many small oval structures that filter the lymph received from the lymph vessels-major locations inc. cervical region, axillary region, and inguinal region
lymph nodes
collection channels that carry lymph from the lymph nodes to the veins
lymph ducts
process of disease protection induced by exposure to an antigen
a substance that, when introduced into the body, causes formation of antibodies against it
substance produced by the body that destroys or inactivates an antigen that has entered the body
an immunity that protects the body against a future infection, as the result of antibodies that develop naturally after contracting an infection or artificially after administration of a vaccine
active immunity
an immunity resulting from antibodies that are conveyed naturally through the placenta to a fetus or artificially by injection of a serum containing antibodies
passive immunity
presence of red blood cells of unequal size (aniso = unequal)
an abnormally reduced number of all cellular components in the blood
an abnormally reduced number of red blood cells
breakdown of the red blood cell membrane
impaired immunologic defenses caused by and immunodeficience disorder or therapy with immunosupperssive agents
impaired ability to provide an immune response
presence of enlarged lymph nodes
an abnormally reduced number of lymphocytes
presence of large red blood cells
presence of small red blood cells
a decrease in the number of neutrophils
presence of large, irregularly shaped red blood cells (poikilo=irregular)
an increase of immature erthrocytes in the blood
enlargement of the spleen
a syndrome caused by the human imunnodeficiency virus (HIV) that renders immune cells ineffective, permitting opportunistic infections, malignancies, and neurologic diseases to develop; it is a s.t.d. or through exposure to contaminated blood
acquired immunodeficiency syndrome (AIDS)
a condition in which there is a reduction in the number of red blood cells, the amount of hemoglobin, or the volume of packed red cells in the blood, resulting in a diminished ability of the red blood cells to transport oxygen to the tissues
a microcytic-gypochromic type of anemia characterized by a lack of iron, affecting production of hemoglobin and small red blood cells containing low amounts of hemoglobin
iron deficiency anemia
a disorder that results from the incompatibility of a fetus with an Rh positive blood factor and a mother who is Rh negative, causing red blood cell destruction in the fetus; necessitates a blood transfusion to save the fetus
erythroblastosis fetalis
presence, or lack, of antigens on the surface of red blood cells that may cause a reaction between the blood of the mother and fetus, resulting in fetal anemia
Rh factor
presence of antigens
Rh positive
absence of antigens
Rh negative
chronic or acute malignant disease of the blood-forming organs, marked by abnormal leukocytes in the blood and bone marrow; classified according to the types of white cells affected, e.g. myelocytic, hymphocytic, etc.
disorder within the bone marrow characterized by the proliferation of abnormal stem cells (cells that give rise to the different types of blood cells); usually develops into a specific type of leukemia
any neoplastic disorder of lymph tissue, usually malignant, as in Hodgkins's disease
process by which cancer cells are spread by blood or lymph circulation to distant organs
viral condition characterized by an increase in the mononuclear cells in the blood along with enlarged lymph nodes, fatigue, and sore throat
increase in the number of erythrocytes and hemoglobin in the blood
systemic disease caused by the infection of microorganisms and their toxins in the circulating blood
bleeding disorder characterized by an abnormal decrease in the number of platelets in the blood that impairs the clotting process
incision into or puncture of a vein to withdraw blood for testing

test of fluid portion of blood to measure the presence of a chemical constituent (e.g. glucose, cholesterol, etc.)
blood chemistry
battery of automated blood chemistry tests performed on a single sample of blood; used as a general screen for disease or to target specific organs such as a heart profile, thyroid panel, etc.
biochemistry panel (BCP)
chem profile
trade name of the instrument first used to perform automated blood chemistry testing; the abbreviation is sometimes used to identify a chemistry panel
sequential multiple analyzer (SMA)
test to determine infection in the bloodstream by isolating a specimen of blood in an environment that encourages growth of microorganisms; the specimen is observed and the organisms that grow in the culture are identified
blood culture
timed test to measure the rate at which red blood cells settle or fall through a given volume of plasma. Determines amount of infection.
