    Essay On Hypoxia

    • 2238 Words
    • 9 Pages

    Physiological Effects of Decreased Atmospheric Pressure At lower altitudes such as sea level, the main stimulation for ventilation is carbon dioxide. (7) At high altitudes, hypoxia stimulates ventilation. (7) However, hypoxia only stimulates ventilation when the partial pressure of inspired oxygen is reduced to roughly 13.3kPa, and is at an altitude of 3000m or more. (7) When the inspired partial pressure of oxygen is 13.3kPa, alveolar oxygen pressure is 8kPa. (7) As hypoxia continues to…

    infections, doctors prescribe antibiotics to prevent or cure them. There are also some treatments to prevent the cells from becoming their sickle shape. One popular drug is Hydroxyurea, which will activate the genes that make fetal hemoglobin (Hoehn).Which is hemoglobin that will not form into a sickle shape. Another way to try to prevent the sickling of blood cells is to drink water and avoid dehydration, and avoid situations or conditions that will cause their oxygen levels to drop…

    faulty gene (sickle cell trait) where the genes come in pairs when the child gains one faulty gene from the father and another from the mother. Causes: Sickle cell anemia results from a change in the normality of a specific hemoglobin called hemoglobin S. The change in hemoglobin S results from a mutation (point mutation) in which a single nucleotide substitution occurs. In sickle cell anemia a point mutation occurs where the glutamate amino acid of protein forming Deoxyribonucleic acid (DNA)…

    Sickle Cell Anemia (SCA)

    • 770 Words
    • 4 Pages

    Sickle cell anemia (SCA) is a classification of the most common form of sickle cell disease. This class of sickle cell disease is genetic and is caused by the homozygous mutation of the beta-hemoglobin gene (beta S allele) in red blood cells [2]. Individuals who are diagnosed with sickle cell anemia have deformed (sickle shaped) red blood cells that have a lower lifespan [3]. This causes irreversible tissue damage and causes a vaso-occlusive crisis, which is pain in the abdomen, bones and chest…

    Sickle Cell Disease (SCD)

    • 1058 Words
    • 4 Pages

    cell disease (SCD) describes a group of inherited red blood cell disorders. Individuals with SCD have irregular hemoglobin, called hemoglobin S or sickle hemoglobin, in their red blood cells (RBC). Sickle cell anemia is a hereditary disease of the RBCs. Typically red blood cells are formed like a circular shape. This gives them the adaptability to go through even the tiniest veins. Be that as it may, in individuals with sickle cell, the red blood cells have a strange curve shape. When shaped…

    Biochemistry Task 3 A1) There are several differences between the oxygenated and deoxygenated states of hemoglobin. One difference can be seen in the conformational state of the hemoglobin protein. When oxygenated, the protein takes on the T (tense) state; and when deoxygenated, the protein takes on the R (relaxed) state (Hudon-Miller, 2012b). Another difference arises when oxygen binds to the hemoglobin, resulting in a change in the shape of the protein. In the deoxygenated state, the heme…

    "Anemia is a reduction in the total number of erythrocytes in the circulating blood or a decrease in the quality or quantity of hemoglobin" (McCance & Huether, 2014, p.982). There are many causes of anemia and are classified in this manner. There are three classifications: macrocytic-normochromic anemia, microcytic-hypochromic anemia, and normocytic-normochromic anemia (McCance & Huether, 2014). Macrocytic-normochromic anemias encompass pernicious anemia and folate deficiency anemia (McCance &…

    Sickle Cell Anemia Effect

    an inherited blood disorder that mostly affects people of African ancestry, but it can also occur in other ethnic groups such as Middle East and Mediterranean descent (National Institute of Health). The disease affects the hemoglobin molecule in the red blood cells. Hemoglobin helps with carrying oxygen from the lungs and delivering it to different parts of the body. The mutation of this disease makes the cells become abnormal and irregular shaped. As a result, the abnormal crescent shape can…

    Sickle Cell Research Paper

    • 1293 Words
    • 6 Pages

    Sickle cell dieasese causes the body to create abnormal red blood cells. Normal red blood cells are typically shaped like a doughnut, as for sickle cells the abnormal cell has a C-shaped. In Sickle cell anemia, the hemoglobin in red blood cells clumps and stick together causing red blood cells to become stiff and form the C-shaped. When this occur the sickle cell blocks blood and oxygen flow. Anemia take place because the sickle cell breaks down more rapidly than normal…

    abundant supply of red blood cells and a higher concentration of hemoglobin inside their blood which allows for a larger amount of oxygen to be stored in the blood for their deep dive. There are some features about the blood for orcas which enables their ability to dive for more than 15 minutes. Orcas store the oxygen molecules within their bodies and transport these oxygen molecule around their body in a protein called hemoglobin. Hemoglobin is what…
