BLOOD COMPONENTS
Plasma
Liquid portion of blood when not clotted
Oxygen
Carried by blood from lungs to needy tissues
Macrophage
Fierce warrior clean up infections and cell debris
Hemoglobin
Chemical in blood that carries oxygen
Antibody
Chemical produced by immune cells that attaches to antigens so WBCS attack and destroy them
Serum
Liquid portion of blood after clotting occurs
Carbon Dioxide
Waste product of cell metabolism carried by blood for excretion in the lungs
Neutrophil
First in the fight against in an invasion by a foreign antigen
Iron
Necessary mineral for hemoglobin function
Thrombocytopenia
Decreased numbers of platelets in the blood
Immune cells
Ingest foreign agents and produce antibodies
Buffer
Maintains acid-base balance in the body
T-Lymphocyte
Kill foreign cells, live a long time and have a memory of past events
Bone marrow
Tissue where RBCS are formed
Pus
An accumulation of WBCS at the site of an infection
platelets
Cell fragments that help in clotting
Erythropoietin
Hormone made in the kidneys and liver to produce RBCS
B-Lymphocytes
Produce antibodies
Anemia
A deficiency of RBCS in the blood
Cardiovascular system
Distributes blood throughout the body
Clotting factors
Chemicals in blood that assist in the clotting mechanism
Heparin
Natural anti-coagulant to reduce the risk of unwanted clots
White blood cell count
Total numbers of WBCS in a given blood volume
Hematocrit
The amount of RBCS in a given volume of blood. Measured in percent
Calcium, fibrinogen, thrombin
Involved in the blood clotting mechanism
