Anemia is a reduced level in a total number of red blood cells

Anemia is a reduced level in a total number of red blood cells. Red blood cells carry hemoglobin, a protein that empowers them to carry oxygen to lungs and deliver it to all parts of the body. When their numbers are low, it is difficult for them to carry an adequate supply of oxygen. An inadequate reserve of oxygen causes symptoms of anemia. Blood is made up of two parts, the liquid part which is the plasma and the cellular part which is composed of different cell types. One of the most significant and abundant cells are the red blood cells (Nabili, 2017). Red blood cells are manufactured in the bone marrow. Detecting the reasons why the red blood cells level is low, will guide to an investigation if it is caused by factors such as increased blood loss in bleeding, decreased production of RBCs in the bone marrow or from the excessive destruction of red blood cells (
Anemia is also induced by other diseases. Some diseases can affect the body’s ability to produce red blood cells. In patients with kidney disease, anemia may develop because kidneys are not functioning well in order to manufacture the hormone erythropoietin, that will prompt the bone marrow to make new or redder blood cells (American Society of Hematology,2010).
