  • Red Blood Cells

    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

  • Synthetic Red Blood Cells

    SYNTHETIC BLOOD This is an artificial blood made up of synthetic blood products. 1. The two main types of non-cellular blood products are hemoglobin based and Perfluorocarbon (PFC) based. a. Hemoglobin The hemoglobin-based substitutes use hemoglobin from several different sources: human‚ animal‚ and recombinant. Human hemoglobin is obtained from donated blood that has reached its expiration date and from the small amount of red cells collected as a by-product during plasma donation.

  • Rafael, the Red Blood Cell

    Hi! My name is Rafael‚ the Red Blood Cell‚ doctors call me erythrocyte and born in the bone marrow. My shape is bi-concave disk. Also do not possess a nucleus. I am one of trillions of red blood cells that live inside and travel through your body. I deliver oxygen to all the organs and tissues and transport wastes as carbon dioxide out of your body. Oxygen helps keep the body running and healthy.  I tend to jump aboard the train inside the heart. The trip around the body only takes 45 seconds

  • Bio-Red Blood Cell Journey

    My Journey Through the Human Body My name is Ruby; I am a red blood cell. I am a dazzling ruby red color (hence my name) with a small area of inner pallor and I am very small: only about 6 µm in diameter. I get my red color from a protein chemical called hemoglobin‚ which is bright red. Hemoglobin not only gives me my beautiful color‚ it also contains the element iron‚ which makes it a good vehicle for transporting oxygen and carbon dioxide. I have a very important role in the circulatory system

  • Erythrocytes: Red Blood Cells

    Task 1a:  Erythrocytes: These are also known as red blood cells and contain haemoglobin with their primary function being to carry oxygen from the lungs then disperse it into the tissues throughout the body through a series of capillaries. The distinctive red colour of the erythrocytes or red blood cells is due to their contents of haemoglobin. In order to facilitate its purpose the erythrocytes can be described as biconcave in shape therefore enabling them to diffuse oxygen around the body with

  • Determining the Isotonic solution in Sheep Erythrocytes Isotonic solution of red blood cells (Laboratory) red blood cell sizes in saline red blood cell expansion in salt

    Introduction Every cell is selectively permeable to different molecules. This type of selectively is caused by a semi-permeable membrane‚ which allows the movement of certain molecules across it. Water exchange can be measured in two ways: RBC osmotic permeability is measured‚ and diffusional water permeability is measured (Benga and Borza 1995). Diffusion is the movement of high concentration to low concentration. The diffusion of water across a permeable membrane is called osmosis. Water concentration

  • Red Blood Cell and Red Bone Marrow

    1. Hemopoiesis is the process of blood cell formation‚ which occurs primarily in the red bone marrow. 2. Hemopoiesis begins with undifferentiated cells called hemocytoblasts. 3. These stem cells give rise to many different cell types that make up the cellular elements of blood. 4. What types of hormones influence the differentiation of the blood stem cells? (CSF’s) Colony Stimulating Factors 5. What are the two lines of cells that differentiate from the hemocytoblast

  • Thalassemia: Red Blood Cell and Hemoglobin Protein Chains

    treatment of Thalassemia. WHAT IS THALASSEMIA? Thalassemia is genetic disorders that involve the decreased and defective production of hemoglobin‚ a molecule found inside all red blood cells (RBCs) that transports oxygen throughout the body (Miller‚ Thalassemias‚ 2008). As (Hashemi‚ 2011) says "Thalassemia is blood disorders ". As (Clinaero‚ n.d.) says" There are mild and severe forms of the disorder as well. Severe Thalassemia is often called Cooley’s anemia". There are two main types of Thalassemia
