  Kidneys and  its functions Like the liver, kidneys play a vital role in maintaining the body's normal state (homeostasis). There are two kidneys in the human body. The nephron is the basic functional unit of the kidney. Each kidney has about a million nephrons. Each nephron has two main parts. Each nephron functions independently to produce urine.  This means that over 99 percent of the filtered water, all the glucose and vitamin C, almost all amino acids, sodium and other substances are returned to the blood. But if the intake of salt exceeds the body's needs the excess is excreted and extra water is needed to excrete it. Functions of Kidneys The kidneys help to regulate the internal harmony by performing the following functions:  1. Filtration: The kidneys are the filters through which all dissolved substances pass and selectively absorb those to be retained. Figure 30.1 depicts the urinary system.

They also maintain the body's backup store of quick energy as glycogen . Human energy is measured in heat units called kilocalories, which is abbreviated as kcalories or kcal . Each gram of carbohydrate consumed yields 4 kcal of body energy. In a well balanced diet, carbohydrates from all sources should provide approximately 45% to 65% of the total kilocalories. Fats Dietary fats from both animal and plant sources provide the body's secondary or storage form of energy. This form is more concentrated, yielding 9 kcal for each gram consumed. In a well balanced diet, fats should provide no more than 20% to 35% of the total kilocalories. Approximately two thirds of this amount should be from plant sources, which provide monounsaturated and polyunsaturated fats, and no more than 10% of kcals should come from saturated fat. Proteins Idea...
