 Most of the food is ingested in forms which are unavailable to the organism, since they cannot be absorbed from the gastrointestinal tract until they have been reduced to smaller molecules. The break down of the naturally occurring food stuffs into assimable forms is the work of digestion. 

 Excretion may be defined as the separation and elimination of the metabolic wastes from the body usually in an aqueous solu tion. The waste materials are of several kinds and vary not only from animal to animal, but also in the same animal from time to time. However, the term excretion is generally used with reference to the elimination of the nitrogenus waste products. from the animal body. During the oxidative metabolism of carbohydrates, carbon dioxide and water are formed as excretory products. The bile pigments bilirubin and biliverdin that are formed in the liver by the break down of haemoglobin are excretory substances which pass out through the intestine. The breakdown of proteins results in amino acids, the excess of which are excreted. While some aquatic animals excrete their extra nitrogen in the form of amino acids as such, most of the animals degrade their excess amino acids to ammonia, uric acid or urea. Deamination The first stage in the breakdown of amino acids ...

VITAMINS Vitamins are complex organic substances found in various foods, which are required for specific metabolic reactions within the cells. In 1912 Dr. Casimir Funk of the Lister Institute of London proposed the name vitamines for these accessory food factors (Hopkins, 1906). Funk isolated the antiberiberi substance in pure form from rice polishings. Since the active factor was an amine, and necessary for life, he introduced the term "vitamin". This term has been retained to designate accessory food factors that are neither amino acids nor inorganic elements. Since not all these substances are amines, the term was later modified to vitamins by  dropping the terminal "e", by Sir. J.C. Drummond in 1920, who also proposed their alphabetical nomenclature... CLASSIFICATION The vitamins are generally divided into 2 major groups: fat-soluble and water-soluble. The fat-soluble vitamins, which are usually found associated with the lipids of natural foods, include vitamin ...

Many doesn't know what is actually the term Anthropology here is it? Anthropology is the scientific study of humanity, concerned with human behavior, human biology, cultures and societies, in both the present and past, including past human species. In simple words it's the combination of science and history background. There are different types of Anthropology: × Social anthropology × Cultural anthropology × Linguistic anthropology × Biological or physical anthropology × Visual anthropology Social anthropology:  Social anthropology studies patterns of behaviour of the human being and the animals.   Cultural anthropology: Cultural anthropology deals with cultural meaning, including norms and values of the human being. Linguistic anthropology:  Linguistic anthropology studies how language influences social life of the human being and the animal. Biological or physical anthropology:  Biological or physical anthropology studies the biological development of humans and pr...
