and develop. The thyroid gland is located in the lower part of the neck‚ below the Adam’s apple‚ wrapped around the trachea. It has the shape of a butterfly with two lobes attached to one another by a middle part called the isthmus. The thyroid uses iodine‚ a mineral found in some foods and in iodized salt‚ to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3). The thyroid gland also makes the hormone calcitonin‚ which is involved in calcium metabolism

Part 1: INTRODUCTION TO HYPERTHYROIDISM Hyperthyroidism is a large topic so we have split it into four manageable sized portions. This page introduces hyperthyroidism. Subsequent pages are listed at the bottom which address more specific details of making the diagnosis of hyperthyroidism‚ the causes of hyperthyroidism‚ and different treatment options available for hyperthyroidism. In healthy people‚ the thyroid makes just the right amounts of two hormones‚ T4 and T3‚ which have important

the reader about Amylase’s ability to withstand acidic or basic pH. To do this‚ two test tubes were both filled with 5mL of a 5% amylase solution. The first one was filled with an acid‚ while the other was filled with a base. After dropping liquid Iodine and Benedict’s solution into each one‚ the tube with a basic pH tested positive for glucose. The acidic solution tested (mostly) negative for glucose‚ although there were trace amounts at the bottom. Overall‚ my conclusion is that only acidic solutions
