a group of heredity disorder characterized by abnormal hemoglobin‚ called hemoglobin S (Hb S) in the red blood cells (Kalai et al.‚ 2017). It is a heredity disease which passes from parent to children. It is more prevalent among African America (National Heart-lung and Blood Institute‚ 2016). There is test put in place to screen newborn for sickle cell. An individual can be tested for sickle cell disorder with a blood test called hemoglobin electrophoresis (National Heart Lung and Blood Institute

Lance’s Roll in Blood Doping The controversy of Lance Armstrong doping has its analysts‚ supporters and critics. I agree that what he did was wrong and goes against the ethics of competition and degrades the integrity for those of us who hold the title of an athlete. This opinion coincides with the general thought of the public. But what I have found is that most people are ignorant and naive as to why the doping Lance did is degrading to cycle racing. The degrading of the sport and its proud and

blood cells instead of the regular round disc like shape cells. Red blood cells transport oxygen from the lungs to various other organs and tissues with the help of a protein called hemoglobin. The main cause of sickle cell disease is when hemoglobin mutates into an abnormal type called hemoglobin S. The presence of Hemoglobin S causes red blood cells to be sickle-shaped and rigid‚ making it more difficult for them to flow through blood vessels in the body to deliver oxygen. Therefore‚ the sickled cells

anemia. IDA is a common type of anemia‚ a condition in which the blood does not receive the accurate number of healthy red blood cells. Specifically‚ with this case there is an insufficient amount of iron‚ and thus‚ causing red blood cells to lack hemoglobin‚ which is needed to carry oxygen. Unfortunately‚ when your red blood cells cannot produce what it needs‚ they cannot carry oxygen‚ and you will be exhausted and short of breath. This is most common for both women and individuals who have a diet

40) Describe the structure of a mammalian respiratory system. Include in your discussion the mechanisms of inspiration and expiration. In mammals‚ oxygen first passes through the nasal cavity. The nasal cavity is covered with mucus and cicilia to filter the air. The nasal cavity leads to the pharynx. The pharynx consists of the eustachian tube and the tonsils. The inhaled air then passes to the larynx‚ trachea‚ and bronchi. The bronchi lead to the bronchioles in the lungs. In the lungs the pleural
