Approximate Composition of Human Tissue

Table gives the approximate composition of human tissue. We all know that carbon, oxygen, hydrogen are present in water and other organic building blocks of the body which also contain nitrogen, sulphur and phosphorus. Calcium is an important constituent of the skeletal structures of animals and its role in physiological processes. If the level of calcium concentration falls below half its normal value it leads to severe or fatal tetanic cramps. Table gives the role of these important minerals.
