homozygous H63D‚ homozygous C282Y‚ and compound H63D/C282Y heterozygous. The most common presence of iron overload is found in hepatocytes found in the liver. To estimate the degree of this disorder‚ a liver biopsy was performed on approximately two thousand patients in the bariatric surgery program. Of those two thousand patients‚ 84% had normal liver with no sign of overload and 16% exhibited some form of iron overload‚ either in hepatocytes‚ Kupffer cells‚ or both. DNA was obtained from these patients

1. Our digestive system provides the body a means to transfer nutrition from the external environment into the cellular level in order to sustain life. Salivary glands‚ controlled by the autonomic nervous system‚ are located in the oral cavity. Its main role is to secrete saliva in the oral cavity. There are three pairs of salivary glands. Parotoid savary gland lies under the skin on each side of the mandible. These glands secrete amylase‚ an enzyme that breaks down starches. The parotoid duct implies

BILIRUBIN FORMATION AND EXCRETION Bilirubin‚ the principal pigment in bile‚ is derived from the breakdown of hemoglobin when aged red blood cells are phagocytized by the reticuloendothelial system‚ primarily in the spleen‚ liver and bone marrow. About 80% of bilirubin formed daily comes from the degradation of hemoglobin. The remainder comes from destruction of heme-containing proteins and catabolism of heme. When hemoglobin is destroyed‚ the protein portion‚ globin is reused in the body. The

Mammals convert ammonia into urea. Urea is formed in the liver by the ornithine cycle; it’s less soluble than ammonia and less toxic. This means that less water is required for excretion. Urea is soluble in blood plasma and is transported to

By dividing blood into proteins like albumin‚ white blood cells and red blood cells clinics are assisted in curing patients. An example is a patient with liver failure being provided with blood plasma that contains the clotting factor. Whilst plasma has an anti-coagulant that prevents clotting‚ serum does not contain the plasma proteins which play a part in clotting such a fibrinogen which is converted to
