Cynthia Chicas July 19th 2010 Dr. Youseff Anemia Anemia is a blood disease where the body does not produce enough red blood cells. Each red blood cell carries hemoglobin (oxygen) to all tissues of the body and also removes carbon dioxide waste by carrying it to the lungs to be exhaled. When a person has Anemia they have less amount of hemoglobin or oxygen in their blood. Anemia is one of the most common blood disorder and can cause many problems with the body. There are many different forms of anemia

in which there are not enough red blood cells or hemoglobin in the body. Red blood cells and hemoglobin carry oxygen through the body. When a baby has anemia‚ her or his body cannot get enough oxygen. Untreated‚ some types of anemia can lead to developmental delays and are associated with lower standardized test scores later in life. Most babies develop a type of anemia called physiologic anemia when they are 6–9 weeks old due to a normal breakdown of red blood cells. Physiologic anemia is usually

Hemolytic Uremic Syndrome (HUS)‚ is a referred to as a disease characterized by hemolytic anemia‚ caused by the destruction of red blood cells‚ acute kidney failure (uremia)‚ and a low platelet count (thrombocytopenia). Although‚ it mostly affects children‚ there have been cases of adults with this illness. The destroyed red blood cells block the filtering system in the kidneys‚ which can lead to a life-threatening kidney failure. HUS usually develops in children after five to 10 days of diarrhea

Cell Osmotic Fragility‚ Solute Permeability and Diffusion Potentials of Permeable Membranes Introduction This experiment examines cell membrane permeability‚ osmosis and membrane voltages; all of which are important in understanding how cells are affected by their environment. The movement of water across membranes is important for cell volume and thus the volume of extracellular compartments. The mechanisms for solute transport are essential in maintaining cell functions and homeostasis. Furthermore

What Are Thalassemias? Thalassemias (thal-a-SE-me-ahs) are inherited blood disorders. "Inherited" means that the disorder is passed from parents to children through genes. Thalassemias cause the body to make fewer healthy red blood cells and less hemoglobin (HEE-muh-glow-bin) than normal. Hemoglobin is an iron-rich protein in red blood cells. It carries oxygen to all parts of the body. Hemoglobin also carries carbon dioxide (a waste gas) from the body to the lungs‚ where it’s exhaled. People

Learning Objectives 1. Understand the terms hematocrit‚ red blood cells‚ hemoglobin‚ buffy coat‚ anemia‚ and polycythemia. 2. Understand how the hematocrit (packed red blood cell volume) is determined. 3. Understand the implications of elevated or decreased hematocrit. 4. Understand the importance of proper disposal of laboratory material that comes into contact with blood.

Lab Report Microscopic Study: Investigating Osmosis in Red Blood Cells Lab Report Investigating Osmosis in Red Blood Cells Introduction: The flow of water across a permeable membrane is called osmosis‚ and during this process‚ water moves down its concentration gradient. A solution surrounding a cell is hypertonic if it contains more solute particles than the inside of the cell‚ and the water will move out of the cell into the surrounding hypertonic solution by osmosis. If the solution

group consists of an iron (Fe) ion held in a heterocyclic ring. Iron binds with oxygen. Therefore‚ it has a very important role in transporting oxygen in the blood. How is iron stored and transported in the body?1 Approximately two-third of the iron in the body is stored in hemoglobin. The Surplus iron that is not available directly in the blood is stored in the iron-storing proteins known as ferritin. When dietary iron has been plentiful‚ ferritin is constantly and rapidly made and broken down‚ providing
