College Answer

The answer structure should have utilized the headings provided in the question. Many candidates described the physiology of calcium, which while related, did not attract marks. The distribution section required not only the sites of distribution but also the percentages found in each. The regulation should have included both primary and secondary mechanisms and an outline on the factors affecting renal excretion, intestinal absorption and release from bone etc. An outline of the physiological role of phosphate required a broad knowledge of physiological processes.
