About functional morphology of organism: segmentation and compartmentalization of biosystem

Segmentation and compartmentalization are two sides of development of organisms in evolution and ontogenesis with complication of their structure and increase of effectiveness of their function. Evolution uses such way of individual development differently - from simple segmentation of animal body (metamerism of Annelida) to quasi-segmentation in human body and similar animals (periarterial complexes of organs). It is possible combinative employment both methods of individual organization. Thus, there are both principles in construction of lymphatic system - classic metamerism (first stage of the organization - basic chain of intervalvar segments) and periarterial quasi-segmentation in composition of individual body (integrative cardiovascular system system). This is possible to use sources of energy in surroundings of lymphatic bed for lymph flow and motion the whole bed, including development as vascular system, so organism at whole. It is possible combination such processes as polymerization and polycondensation.
