These changes represent a body's response to particular situations, so (Piandiscò cease the conditions that led to the reduction or increase in red blood cells, their numbers more or less rapidly returns to normal.
also causes pathological concentration of red cells may move away from the average values, increasing or decreasing.
An increase can be seen, for example, in individuals who suffer from emphysema or other respiratory disorders that prevent a perfect oxygenation of the blood, or who have congenital malformations of the heart, or are poisoned by chemicals ( arsenic, phosphorus, etc.).. A remarkable number of red blood cells you have in polyglobulia, a disease caused by an alteration of the bone marrow that produces an enormous amount of red blood cells in some cases, even if they are found 14 million per cubic millimeter.
A reduction of erythrocytes occurs but in those diseases which are known by the name of anemia. However, their value can not fall below a certain limile: seems that the minimum number of red blood cells compatible with life is around 1 million per cubic millimeter.
white blood cell count: The value
normal white blood cell (WBC) is 5000-10000 per cubic millimeter of blood. The methods of sampling and counting are similar to those used for red blood cells. As for red blood cells, the number of leukocytes can vary both in physiological and in pathological conditions. A physiological increase of white blood cells (leukocytosis), we have to example in pregnancy, during childbirth, the period of menstruation or in response to particular moods (fear, pain, etc.).. Leukocytosis, this time as an expression of disease states, it can also be found in leukemia, and in some infectious diseases and infections.
Other infectious diseases cause a decrease instead of leukocytes (leukopenia) and the same situation is found in following the action detrimental to physical or chemical agents on the bone marrow (as is the case with X-rays and benzene).
