Document Summary
1904; walter noel severe anemia and debilitating muscle pain (dr. ernest irons and james herrick) Fewer red blood cells: different red blood cell shape, morphology of plasma membrane is misshapen. Anemia clinical condition that results from abnormally low numbers of red blood cells (rbcs) Rbcs contain haemoglobin that is capable of transporting oxygen from the lungs to the target tissues: hypoxia = low oxygen = fatigue. Anemia may be temporary due to disease of nutrition (eg/ low iron levels) Hereditary anemia is associated with abnormalities in haemoglobin structure. Due to shape disfigurement of sickle shaped red blood cell, transport through capillaries is compromised get stuck in capillaries. Many symptoms are due to cells that are dying due to lack of oxygen. Sickle shaped red blood cells elongated; can carry oxygen, just can"t be transported. Some areas of the body are completely cut off of oxygen.
