Blood Vocab
Defending the body against bacterial infection and invasion by foreign substances is a function of
White blood cells
Infections generally result in an increase in the number of
White blood cells
Lymphocytes
White blood cells which produce antibodies
Serotonin
As a platelet plug forms, platelets release this vasoconstricting substance
Mature red blood cells do not have a
Nucleus
Newborns are sometimes exposed to fluorescent light as a treatment for this
Physiologic jaundice
Antibodies
React with antigens and inactivates them
The biconcave cells in blood that lack nuclei when they are mature are
Red blood cells
In an adult, red blood cells are produced primarily in the
Red bone marrow
Lymphatic System
Returns tissue fluid to the blood
Thrombin
Serves as an enzyme in the blood coagulation mechanism
Fibrin
Strands of protein involved in clotting
Plasma
Liquid part of the blood
The normal blood cell count is between how many cells per cubic centimeter of blood
5,000 to 10,000
Heparin
A blood clot-inhibiting substance released by basophils
Prothrombin test
A blood test used to evaluate extrinsic clotting factor
A primary function of lymphocytes is to
Act against foreign substances
Leukopenia
An abnormally low white blood cell count
The smallest percentage of of leukocytes is
Basophils
An abnormality involving the platelets would probably affect the process of
Blood clotting
Erythroblastosis
Can be preventing Rh negative mothers with anti-Rh aggulutinin
Leukemia
Cancer of the bone marrow
Platelets
Cell fragments involved in clotting
Anemia
Condition in which the blood cannot carry sufficient oxygen
This condition is caused by an increased blood concentration of carbon dioxide and results in skin becoming what color
Cyanosis, blue
Platelets are best defined as
Cytoplasmic fragments of cells
The basic event in the formation of a blood clot is the change of
Fibrinogen to fibrin
Antigens
Foreign molecules in the body
Sickle-cell anemia is caused by an abnormal form of this
Hemoglobin
The iron-containing molecule in red blood cells is called
Hemoglobin
This is the element included in hemoglobin molecules
Iron
Hemoglobin
Iron-containing molecule in red blood cells
Erythropoietin
The hormone released from the kidneys that promotes the production of red blood cells
Neutrophil
The most common type of leukocyte in a blood sample
Hemostasis
The term used to describe the stoppage of bleeding by any one of several means
Differential white blood cell count
The test in which the percentages of various types of leukocytes in a blood sample is determined
Red blood cells
Transport oxygen from the lungs to the cells
