Question

The abnormal increase in the total RBC count is referred to as
A. Pneumonia
B. Polycythaemia
C. Leucopenia
D. Anaemia

Answer 1

Hint:An essential element of the blood is red blood cells. In return for carbon dioxide, which is delivered to and removed by the lungs, their role is to transport oxygen to the body’s tissues. In the red bone marrow of your bones, red blood cells are created. The word poly means many.

Step by step answer:Polycythemia relates to a spike in the body’s number of red blood cells. The extra cells make the blood thicker and, in turn, raises the risk of other health complications, such as blood clots. Polycythemia may have multiple causes, and each one has its own options for treatment. Polycythemia treatment includes treating any underlying disorders, if feasible, and finding ways to lower the levels of blood cells. The red cell and its haemoglobin purpose is to bring oxygen to all body tissues from the lungs or gills and to bring carbon dioxide, a waste product of metabolism, to the lungs from where it is excreted.
Hence option B is correct.
Additional Information: Leucopenia is a decrease in the number of cells in the blood that are WBC. A defect in the number or consistency of red blood cells is anaemia. In anaemic individuals, a lack of iron
is seen. Pneumonia is an inflammatory lung disease that mainly affects the microscopic air sacs known as alveoli.

Note: The mature red blood cell in humans is small, round, and biconcave; in shape, it appears
dumbbell-shaped. The cell is versatile and, as it moves through incredibly narrow blood vessels, takes a bell shape. It is coated with a membrane of lipids and proteins, lacks nucleus, and contains oxygen-binding haemoglobin, a red iron-rich protein.
