Answer #1

Answer

  • The chemoreceptors on parathyroid gland detect low blood calcium levels.
  • Parathyroid gland secretes a hormone PTH that tends to increase blood calcium levels.
  • PTH acts on bones cells to increase bone resorption, it increases absorption of calcium in intestine as well as increase calcium reabsorption in kidneys.
  • If antibodies attack these chemoreceptors, they will not longer be able to sense decrease blood calcium levels.
  • As a result, parathyroid hormone will not be secreted. The levels of PTH in blood will also decline.
  • Blood calcium level will continue to deline leading to many physiological conditions.
