It is simple in that, on the outside, the goals of our body may appear few. We internalize food, water, and oxygen while at the same time ridding ourselves of carbon dioxide and other waste materials. These operations support reproduction, growth, maintenance, and defense. Yet on the inside our body may seem very complex as various organs participate in a tremendous number of complicated processes intended to meet the simple goals previously mentioned....

  • Anthropometrics Anthropometric measurements provide information on body muscle mass and fat reserves. The most practical and commonly used measurements are body weight, height, triceps skinfold (TSF), and mid-arm muscle circumference (MAMC). Body weight is one of the most useful nutritional parameters to follow in patients who are acutely or chronically ill. Unintentional weight loss during illness often reflects loss of lean body mass (muscle and organ tissue), especially if it is rapid and not caused by diuresis.
