Question

Question 1 1 pts By identifying the number of different types of white blood cells in a patient's blood, a clinician can have an idea of what is causing the patient's disease. True O False

Answer 1

True

Explanation: The five major types of white blood cells are:

1. Neutrophils:destroy bacteria and fungi, Increased levels of neutrophils in the body lead to physical state known as neutrohilic leukocytosis. This condition is a normal immune response to an event such as infection, injury, inflammation etc

,2. lymphocytes:Vital for producing antibodies that help to defend against bacteria, viruses.High levels of lymphocytes may result of a virus infection such as tuberculosis.

3. Eosinophils:Responsible for destroying parasites and cancer cells. High levels of eosinophils shows that the body is reacting to a parasitic infection.

4. Monocytes: Responsible for attacking and breaking down germs and bacteria. High levels of monocytes may indicate the presence of chronic infection, an autoimmone or blood disorder, cancer or other medical condition.

5:Basophils: alert the body to infections by secreting chemicals into the blood stream mostly to combat allergies.Rising levels may occur in people with a history of underactive thyroid disease, known as hypothyroidism.

Higher or lower numbers of WBC's than normal can be a sign of an underlying condition. For example low WBC count (Leukopenia) can be triggered by HIV, autoimmune disorders, bone marrow disorders or damage, lymphoma, liver and spleen diseases.Also high WBC count ( Leukocytosis) can be triggered by smoking, tumors in the bone marrow, leukemia, asthma, tissue damage
