Abstract:
The animal body presents a system, in which during the ontogenetic development many processes are regulated by the circulatory system. It ensures the blood circulation through vessels and the exchange of substances between tissues and organs, thus guaranteeing a structural and physiological development of organs, systems and the entire organism. During the body development, the vascular system undergoes certain morphological changes that are in strict accordance with the organs changes at different stages of growth. Following the aforementioned, the examination of development laws of the vascular bed gives us the possibility to know the development trend of the organs, systems and the whole body, for establishing as precisely as possible the period of female rabbit physiological and sexual maturity.
