Body composition may also be analyzed in terms of molecular type, for example, water, protein, connective tissue, fats, carbohydrates, and DNA. In terms of tissue type, the body may be analyzed into water, fat, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body are not human cells, but consist of bacteria residing in the normal human gastrointestinal tract.
