Do you know what is erythropoietin?

Don't you know that our body produces glycoprotein hormone called erythropoietin.. ?Nice name huh??[buleh buat name anak nie..hehehe....] also known as EPO. This hormone is produced by specialized kidney cell and very sensitive to low oxygen level in our blood. If oxygen (O2)level is low, the cell will release EPO and EPO will stimulate the bone marrow to produce more red cell. When more red cells are produced the O2 carrying capacity will increase in our blood.
