Hyperphosphatemia, that is, an abnormally high serum phosphate level, can result from increased phosphate (PO4) intake, decreased phosphate excretion, or a disorder that shifts intracellular phosphate to extracellular space. (See Pathophysiology, Etiology, Clinical Presentation, and Workup.)
Geography (from Greek Î³ÎµÏÎ³ÏÎ±ÏÎ¯Î±, geographia, literally earth description) is a field of science devoted to the study of the lands, the features, the inhabitants, and the phenomena of Earth. The first person to use the word Î³ÎµÏÎ³ÏÎ±ÏÎ¯Î± was Eratosthenes (276â194 BC).
