Anatomy And Physiology Sickle Cell Disease Essay

Brittany Alvarez December 16, 2016 Anatomy and physiology Final Paper – Sickle cell disease Sickle cell disease, also called sickle cell anemia is a group of disorders that affects the molecule in red blood cells that deliver oxygen to the cells. Approximately 100,00 people in America are affected by this disease. Sickle cell disease is an inherited disease, which means it is passed from parents to their children. This disease occurs mainly in people if African, middle eastern, Mediterranean, and Indian decent. People who are born with sickle cell disease inherit two abnormal hemoglobin genes called sickle hemoglobin, or hemoglobin S. Normal red blood cells are round and flexible but in a person with sickle cell disease their blood cells are crescent or sickle shaped and they are not flexible. The sickle-shaped cells can stick to the wall of the blood vessel and cause a blockage that can stop or slow the flow of blood. The blockage of blood prevents oxygen from reaching nearby tissues. Sickle cell disease is not contagious. It occurs when a child inherits two hemoglobin S genes, one from each parent. In the united states, about 2,000 babies are born with sickle cell disease each year. Children who only inherit one hemoglobin S gene have sickle cell trait, they do not have sickle cell disease. People with sickle cell trait do not suffer any side effects that people who have sickle cell disease suffer from. Someone who has sickle cell trait carries oneShow MoreRelatedReview Of The War On Malaria 1736 Words   |  7 Pages THE WAR ON MALARIA JAYME SWANSON BALTIMORE CITY COMMUNITY COLLEGE DR. SAMUEL ODEDOKUN ANATOMY AND PHYSIOLOGY II OCTOBER 19, 2014â€Æ' The War on Malaria About 3.3 billion people, that is about half of the world’s population are at risk of contracting malaria (figure 1). Every year there are 250 million cases of malaria, and nearly 1 million deaths. That amounts to 2,732 deaths per day. Out of those million people that die every year, 800,000 of them are African children under the age of 5.Read MoreThe Medical Promise Of Embryonic Stem Cells1626 Words   |  7 PagesEmbryonic Stem Cells Why should people suffer from diabetes, Alzheimer’s, sickle cell anemia, leukemia, and plenty of other degenerative diseases while the cure lies in our hands? After James Thompson, a developmental biologist, reported that he had derived the first human embryonic stem cell line (Thomson), the potential of curing degenerative diseases was revealed. Ph.D. holder and deputy director of FDA’s office of Cellular, Tissue and Gene Therapies, Stephanie Simek, explains that stem cells are unspecializedRead MoreThe Cell Cycle And Dna Replication1690 Words   |  7 PagesQuestion 1: a) The two processes, with which a cell passes this DNA sequence onto other cells, are DNA replication and mitosis. The cell cycle is inclusive of mitosis and DNA replication, the latter of which occurs in the S phase (synthesis) of the cycle. The goal of the S phase is to create two identical semi-conservative chromosomes. The enzyme helicase unwinds the parental DNA double helix strand and uses it as a template so the enzyme DNA polymerase can attach free-floating nucleotides to theRead MoreDarwinian Medicine : An Evolutionary Perspective1283 Words   |  6 PagesDarwinian Medicine Darwinian medicine, unlike most medical research that is focused on the proximate causes of diseases, looks at diseases from an evolutionary perspective; it seeks the reasons behind why natural selection has favored certain characteristics that are involved in disease acquisition or prevention. It looks into several concepts of adaptation including which types of adaptations combat pathogens, adaptations that pathogens have developed to counter other organism’s adaptations, maladaptiveRead MoreLab Report On The Concentration Of Haemoglobin2734 Words   |  11 Pagesand to adapt this method to determine percentage haemoglobin F (foetal haemoglobin) in an unknown sample, and to understand the relevance of these tests in the calculation of Hb concentration. Haemoglobin is a protein molecule found in red blood cells (RBC). Its role in the body is to transport oxygen from the lungs to the body s tissues and then returns carbon dioxide from the tissues back to the lungs. The transportation of oxygen is only possible when haemoglobin (Hb) within the RBC binds toRead MoreBlood Of Blood And Blood994 Words   |  4 PagesBlood typing involves properly identifying protein substances known as antigens that may or may not be present in red blood cells. Many different antigens most important are the ones we observed in this lab ABO and Rh groups. In order to determine which antigens are present, we gathered synthetic blood sample and mixed with blood-typing serums that contain antibodies. If a specific anti body connects with an antigen a reaction takes place. This reaction can be seen when blood clumps together (agglutinationRead MorePhysio-Ex Blood Analysis: Computer Simulation2907 Words   |  12 Pageserythrocyte sedimentation rate, hemoglo bin determination, blood typing, and total cholesterol determination. A â€Å"hematocrit refers to the percentage of red blood cells (RBC’s) in a sample of whole blood. Since the function of red blood cells is the transport of oxygen to the cells of the body, the higher the hematocrit, the more red blood cells are available to carry oxygen.† In a normal, healthy male the value for males is 47% and in a normal, healthy female it is 42%.

He had the understanding that the environment in which one is surrounded by can be both positively and negatively affecting to one’s health. Hippocrates discovered the theory of the four humors; blood, phlegm, yellow bile, and black bile. According to him, each humor corresponded with its own season, element, organ, and so on. The deficiency or imbalance of any one of t hese humors was thought to be the cause of disease and illness. He strongly believedRead MoreKarl Landsteiner, The Brilliant And Skillful Scientist From Early Twentieth Century Vienna Essay2390 Words   |  10 PagesLandsteiner was named to the position of head assistant in the department of pathological anatomy at the University of Vienna. He worked under Dr. Weicheslbau who was the first person to discover meningitis. He also worked under Dr. Frawncke, who discovered the pneumococcus virus. Working under these two doctors was a very beneficial opportunity for him. While in the assistant position, he began to study morbid physiology. After 20 years of hard work, Landsteiner eventually published papers along with aRead MoreAssessment of the Patient with Acute Abdominal Pain5527 Words   |  23 Pagesconditions.
