Sickle Cell Anemia The definition for sickle cell anemia is an abnormal‚ rigid‚ sickle shape. Sickling decreases the cells flexibility and results in a risk of various complications. Sickle cell is the name of a specific disease in which there is a homozygosity for the mutation that causes Hbs. This type of disease‚ usually presenting in childhood‚ occurs more commonly in people from parts of the tropical and sub-tropical regions where malaria is more common. If a person has sickle cell anemia

Describe the important components and major functions of blood. • Blood performs a number of functions dealing with: • Substance distribution • Regulation of blood levels of particular substances • Body protection • Blood transports: • Oxygen from the lungs and nutrients from the digestive tract • Metabolic wastes from cells to the lungs and kidneys for elimination Hormones from endocrine glands to target organs • Blood maintains: • Appropriate body temperature by absorbing

Sickle Cell Anemia Pathophysiology: Sickle cell anemia is a disease passed down through families in which red blood cells form an abnormal crescent shape. The “sickling” occurs because of a mutation in the hemoglobin gene. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain‚ serious infections‚ and organ damage. Life expectancy in people who have this disease is shortened. Anemia is a condition in

Sickle-Cell Anemia is an inherited‚ chronic blood disease in which the body produces abnormally shaped red blood cells. When the blood cells become crescent/sickle shaped‚ they are unable to deliver adequate amounts of oxygen to other cells. Also‚ these unusual “sickle” cells block blood pathways to the limbs and organs‚ limiting the amount of blood flowing throughout the body. It causes pain‚ organ damage‚ and anemia (low blood count). Unfortunately‚ however‚ when sufferers are born with this disease

is lowered‚ these cells change their forms from the normal biconcave disk to crescent‚ holly wreath‚ and other forms. This process is known as sickling. What is Sickle Cell Anemia? It is a blood disorder that affects hemoglobin‚ red blood cells with normal hemoglobin move easily through the bloodstream‚ delivering oxygen to all of the cells of the body. Normal red blood cells are shaped like doughnuts with the centers partially scooped out and are soft and flexible. Sickle cell anemia occurs when

that sickle cell anemia affects about 72‚000 Americans in the United States. Sickle cell anemia is an inherited disease in which the body is unable to produce normal hemoglobin‚ an iron-containing protein. Abnormal hemoglobin can morph cells that can become lodged in narrow blood vessels‚ blocking oxygen from reaching organs and tissues. The effects of sickle cell anemia are bouts of extreme pain‚ infectious‚ fever‚ jaundice‚ stroke‚ slow growth‚ organ‚ and failure. Sickle cell anemia hurts

Blood Doping in Endurance Sports Blood doping has become a consistant part of sports and fair play. Blood doping enhances your performance by increasing red blood cell mass and as a result delivering more oxygen to muscle. This “boost” of energy has sparked major controversy in the sports world for what it can do for an athlete during endurance events such as running. The risks involve putting the cardiovascular system of the athlete being in severe danger because of this procedure. Still‚ there
