Polycythemia is defined an abnormal increase in the number of circulating red blood cells. It is mainly caused by a cancerous condition known as myeloproliferative disorder or due to a low supply of oxygen to body tissues usually due to living in high altitude areas and the body tries to compensate by producing more red blood cells to increase oxygen carrying capacity of the blood
Normal blood count values in a male adult is 4.7 to 6.1 million cells/mcL, while in a female adult it is 4.2 to 5.4 million cell/mcL.
If this blood cell count is significantly higher then these values, and remains there or continues to rise, over a given period of time, accompanied with some specific symptoms, then polycythemia is suspected.
Answer:
Cells are the simplest structure to fit all of the characteristics necessary to be considered alive.
Explanation:
The cell (from the Latin cellula, diminutive of cella, ‘hollow’) 1 is the morphological and functional unit of every living being. In fact, the cell is the smallest element that can be considered alive.2 In this way, living organisms can be classified according to the number of cells they possess: if they only have one, they are called unicellular (such as protozoa or bacteria, microscopic organisms); If they have more, they are called multicellular. In the latter the number of cells is variable: from a few hundred, as in some nematodes, to hundreds of billions (1014), as in the case of the human being. The cells usually have a size of 10 µm and a mass of 1 ng, although there are much larger cells.
