Introduction
General Biology:- Biology as a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. It is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics as contained in Biology are five unifying principles that can be said

It is chiefly concerned with the study of how living organisms function including such processes as nutrition, movement, and reproduction. Physiology is derived from a Latin word ‘‘pysiologia’’ meaning science of natural causes and phenomena. Thus, it is often described as the branch of biology dealing with the functions and activities of living organisms as well as functions of their component parts, that includes all physical and chemical processes. The word "function" is important to the definition of physiology because physiology traditionally had to do with the function of living things while anatomy had to do with morphology, the shape and form, of things.
Summarily, it can be seen that:- The branch of bioscience dealing with the study of the functions of form and structure of organisms as well as functions of their specific structural features is Physiology and is a science of wide scope. For instance:- * Some physiological studies are concerned with processes that go on within cells. The physiology of cells is called cell physiology. * Other physiological studies deal with how tissues and organs work, how they are controlled and interact with other tissues and organs and how they are integrated within the living organisms. * Yet other physiological studies deal with how living organisms respond to their environment. For example,…
