5,000 – 10,000 / L
Where would one normally find leukocytes?
In the bloodstream and the tissues.
Most leukocytes travel from the bloodstream into the tissue. True or False?
True. They can go through the capillary wall.
What two leukocytes use phagocytosis to destroy bacteria?
• Neutrophil
• Monocytes
High numbers of this granulocyte may indicate bacterial infection:
Neutrophil
What granulocyte in the normal adult body constitutes 2 – 4% of the total white blood cells?
Eosinophils
High numbers of this granulocyte may indicate large parasites, such as parasitic worms, or allergies.
Eosinophils
What granulocyte in the normal adult body constitutes .5 – 1% of the total white blood cells?
Basophils
What two chemicals do basophils contain in their granules?
• Histamine
• Heparin
What white blood cell releases histamine into damage tissues?
Basophil
What chemical released by the basophils causes vasodilation so that blood can get quickly to a damaged tissue so repairs and defense can occur immediately?
Histamine
Histamine not only causes vasodilation but allows the blood vessels to become more ______________ to neutrophils and clotting proteins.
Permeable
What chemical released by the basophils is an anticoagulant which purpose is to inhibit clotting in the wound so that neutrophils can quickly move around and destroy invaders?
Heparin
What agranulocyte in the normal adult body constitutes 25-33% of the total white blood cells?
Lymphocyte
What agranulocyte may be seen elevated in immune responses, such as against viruses?
