Which white blood cell has the greatest nuclear variations?

neutrophil

Which white blood cell represents the greatest percentage in a normal differential count?

neutrophil

Which of the following have significant functions mainly during bleeding?

platelets

play an important role in stoppage of bleeding (hemostasis)

platelets

A ____________ lacks a nucleus.

red blood cell

______ contain hemoglobin and transport gases between the body cells and lungs

red blood cells

Eosinophil numbers typically increase during allergic reactions.

true

Defend the body against disease

white blood cells

Which of the following have significant functions for destroying pathogenic microorganisms?

white blood cells

Eosinophil

- destroys parasited - helps control inflammation - helps control allergic reactions - elevated during allergic reactions - elevated when parasitic worms are present

Monocyte

- phagocytes dead or dying cells - phagocytes microorganisms - may be elevated in tuberculosis - may be elevated during fungal infections

Neutrophil

- phagocytizes bacteria - nucleus single to five lobes - elevated during stress - elevated during bacterial infections

Lymphocyte

- provides immunity - may be elevated during viral infections

Basophil

- releases heparin and histamine - elevated levels may indicate chicken pox - elevated levels may indicate cancer

Check all the components that are found in the plasma of the blood.

- water - proteins - nutrients - hormones - gases

Order of abundance in normal blood sample

1 -neutrophil 2- lymphocyte 3- monocyte 4- eosinophil 5- basophil

After completing a differential white blood cell count on a blood sample, you find a high number of eosinophils. What are some possible causes that could increase the number of eosinophils? (mark all that apply)

- allergic reaction - parasitic infection - inflammatory reaction
