Protoplasm is a fragile substance keeping its homeostatic properties by many physiochemical phenomena. Much is known about the properties of protoplasm; but it is, perhaps, only meager when compared to what is yet to be learned. Such physical changes as electrical impulses, diffusion, and oxidation – to mention a few – are necessary for protoplasm to retain its integrity. In higher animals, particularity, for our purpose, mammals, protoplasm is sustained by different body system working harmoniously together to supply raw materials that remove waste, and govern all endeavors. One should not infer that single called animals have a more simple type of protoplasm than multicellular animals, for the composition of all protoplasm is essentially the same. Single called animals differ from multicellular animals in their methods of attaining protoplasmic precursors to the cell proper and removal of waste. The major system of the body that help maintain homeostasis are: circulatory, respiratory, nervous muscle, urinary, and endocrine. The endocrine system supplies hormones which are chemicals that function as an indispensable link in the chain of events that occur in the dynamics of protoplasm and hence, the whole organism. Some of the hormones have been vaguely identified, their properties understood, and their function know. Some are a complete mystery; others are just in the infancy of scientific study. The major work presented in this thesis is an investigation into the mysteries of one such hormone, relaxin.
