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).
Geography is part of everyday life and includes the land, weather, economic structure and culture of the world. Clothing styles, for example, are determined by geography because geographical location determines the temperature, climate and available materials for textiles. Studying geography encourages students to think critically about how the surroundings of a culture can trigger the change and development of the society.
