deficiency anemia is the most prominent solitary insufficiency worldwide (Harper‚ 2012). Iron deficiency is described as diminished overall iron content. Iron deficiency anemia transpires if iron insufficiency is critical enough to diminish erythropoiesis (Harper‚ 2012). Iron is essential for all existing beings because it is necessary for numerous metabolic processes‚ “including oxygen transport‚ DNA synthesis‚ and electron transport” (Harper‚ 2012). Iron balance within the body is controlled

Red blood cell From Wikipedia‚ the free encyclopedia [pic] Human red blood cells (6-8μm) Red blood cells (also referred to as erythrocytes) are the most common type of blood cell and the vertebrateorganism’s principal means of delivering oxygen (O2) to the body tissues via the blood flow through thecirculatory system. They take up oxygen in the lungs or gills and release it while squeezing through the body’scapillaries. These cells’ cytoplasm is rich in hemoglobin‚ an iron-containing biomolecule that

module 3 ematology – Module 3‚ Lecture 1 Slide 1 ● The first type of blood cells that we will focus on are the erythrocytes‚ also called the red blood cells. These are the cells that transport oxygen in the blood from the lungs to the tissues. These cells also help transport some of the carbon dioxide from the tissues to the lungs. The main function of erythrocytes‚ namely oxygen transport‚ is carried out by the protein that makes up the majority of the protein composition of the cell

is typically based on a persons signs and symptoms. In those without symptoms they are not recommended unless hemoglobin levels are less than 60 to 80 g/L (6 to 8 g/dL). These recommendations may also apply to some people with acute bleeding. Erythropoiesis-stimulating medications are only recommended in those with severe anemia. Anemia is the most common disorder of the blood with it affecting about a quarter of people globally. Iron-deficiency anemia affects nearly 1 billion. It is more common

grams of iron; that’s more than five times the iron stored by all the other tissues combined. The blood types of humans are due to variations in surface glycoproteins of erythrocytes. The process by which red blood cells are produced is called erythropoiesis. Erythrocytes are continuously being produced in the red bone marrow of large bones. (In the embryo‚ the liver is the main site of red blood cell production.) The production can be stimulated by the hormone erythropoietin (EPO)‚ which is used

It has chlorophyll that has the benefit for the erythropoiesis which is the process of red blood cell production. Moreover‚ Pizzorno and Morray (2000) presented that green tea speeds the function of liver enzyme which helps the liver detoxify better. In addition‚ green tea helps to develop the function of

CHAPTER ONE INTRODUCTION/LITERATURE REVIEW THE ERYTHROCYTES A cell that contains haemoglobin and can carry oxygen to the body. Also called a red blood cell (RBC). The reddish colour is due to haemoglobin. Erythrocytes are biconcave in shape which increases the cells surface area and facilitates the diffusion of oxygen and carbon dioxide. This shape is maintained by a cytoskeleton composed of several proteins. Erythrocytes

Intentional hypothermia Controlled hypothermia plays important role in reducing the oxygen consumption by the body. This step used with Jehovah’s Witnesses since they reject the transfusion. As the body temperature reduced by 5-7°C‚ the oxygen consumption reduced as well by 48% beneath the basic levels and increased in the blood. However‚ the reduction in body temperature below 30°C requires the clinician to monitor the patient to make sure that the patient did not suffer from hypothermia. Even
