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.
Red blood cells (RBCs) are produced in the bone marrow. Red blood cells are also known as erythrocytes and they transport oxygen and carbon dioxide between the lungs and tissues. The production of red blood cells is also known as hematopoiesis; this process occurs in the bone marrow.The bone marrow is found in the spongy tissue in the middle of bones.ed blood cells, or erythrocytes, are made in the bone marrow as are white blood cel â¦ ls or leukocytes and they originate from stem cells. The marrow is located in the length of the long bones until we get older, then it will diminish with age.
