PPT-Lab 4 What is a Red Blood Cell?

A type of blood cell that is made in the bone marrow and found in the blood Red blood cells contain a protein called hemoglobin which carries oxygen from the lungs to all parts of the body The normal RBC . Healthy red blood cells are round and they move through small blood vessels carrying oxygen to all parts of the body In SCD the red blood cells become hard and sticky and look like a Cshaped farm tool called a sickle Sickle cells die early which cau Prepared by:. .

Red blood cell indices are measurements that describe the size and oxygen- carrying protein( hemoglobin) content of red blood cells.. Blood . is the body’s only fluid tissue. It is composed of liquid plasma and formed elements. Formed elements include: . Erythrocytes, or red blood cells (RBCs). Leukocytes, or white blood cells (WBCs).

Unfortunately this disorder can not be cured but can be stabled with the right treatments. In 1973 the average lifespan of a person with sickle cell was only 14 years. Fluids of the Body . Cells of the body are serviced by 2 fluids. blood. composed of plasma and a variety of cells. transports nutrients and wastes. interstitial fluid. bathes the cells of the body. Nutrients and oxygen diffuse from the blood into the interstitial fluid & then into the cells. 55% plasma. 45% cells . 99% RBCs. < 1% WBCs and platelets. Formed Elements of Blood. Red blood cells ( erythrocytes ). White blood cells ( leukocytes ). granular leukocytes. neutrophils. eosinophils. pluripotent stem cells . in the marrow. . They divide into three main types.. Erythropoiesis. , is formation of RBC. Leucopoiesis . (myelopoiesis) is formation of WBC. Thrombopoiesis. is formation of platelets.. Introduction . Red blood cells are characterized by a biconcave shape aids efficient navigation through narrow vessels.. Surface antigens on red blood cells determine individual blood types.. Lack of nucleus and organelles enables high hemoglobin concentration for oxygen transport..
