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.
Bone marrow consists of hematopoietic cells and fat cells which help in producing new cells. It helps in production of the red blood cells and white blood cells and platelets. The function of these cells is to carry oxygen, help the body fight infections.When the production of the white blood cells in the bone marrow gets out of control it causes Leukemia.one marrow cells are constantly dividing and producing various cells in the blood and are very functional. The various blood cells include: 1  Red Blood Cells (RBC)- These perform the function of transferring oxygen from lungs to body You do not have access to view this node.
