Calcium metabolism Calcium metabolism Calcium metabolism refers to the movements and regulation of calcium ions (Ca) "in" and "out" of various body compartments, such as the gastrointestinal tract, the blood plasma, the extracellular and intracellular fluids, and bone tissue. An important aspect of calcium metabolism is plasma calcium homeostasis, the regulation of calcium ions in the blood plasma within narrow limits. In this process, bone tissue acts as a calcium storage center for deposits and withdrawals as needed by the blood, via continual bone remodeling. Derangement of this mechanism leads to hypercalcemia or hypocalcemia, both of which can have consequences for health.
Degree symbol the degree symbol (e.g., 10 °C). However, in many works with professional typesetting, including scientific works published by the University of Chicago Press or Oxford University Press, the degree symbol is printed with no spaces between the number, the symbol, and the Latin letters "C" or "F" representing Celsius or Fahrenheit, respectively (e.g., 10°C). This is also the practice of the University Corporation for Atmospheric Research, which operates the National Center for Atmospheric Research. Though not recommended, use of the degree symbol without a following Latin letter is done so without a space between the number and symbol (e.g., 10°);
