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
