An analogous formula applies to the case of a continuous probability distribution. Not every probability distribution has a defined mean; see the Cauchy distribution for an example. Moreover, for some distributions the mean is infinite: for example, when the probability of the value is for n = 1, 2, 3, ....
Red blood cell (RBC) production (erythropoiesis) takes place in the bone marrow under the control of the hormone erythropoietin (EPO). Juxtaglomerular cells in the kidney produce EPO in response to decreased O 2 delivery (as in anemia and hypoxia) and increased levels of androgens.
The bone marrow normally produces mature red blood cells and the hemoglobin in these cells carry oxygen to the tissues in your body. The percentage of red blood cells in the total blood volume is called the hematocrit.In healthy women the hematocrit is 36% to 46% while in healthy men the hematocrit is 40% to 52%.oth types of marrow contain blood vessels. Stem Cells The bone marrow works like a âfactoryâ that produces all of the cells that are found in the bone marrow and in the peripheral blood stream. This factory is dependent on the function of the pluripotent stem cells.
