The normal functioning of a human body is always due to the efficient work of all its main systems: cardiovascular, respiratory, lymphatic, immune, urinary, digestive, and reproductive. Understanding the structure and operation mechanisms of each particular system is a pivot step towards right care, timely prevention of health-related problems, and life extension of a particular individual. Though performing the variety of functions, all the twelve human body systems make significant contribution to an efficient interrelation of an individual and his environment. Furthermore, understanding peculiarities of functioning of a human organism is important to solve the dualisms between a body and an environment; an individual and population, which have been topical for Western medicine for decades (Solomon, 2000).
The knowledge of human body systems provides an understanding that each particular system cannot exist independently, but needs the assistance of other systems to perform its vital functions. For instance, cardiovascular system plays the primary role in oxygen saturation which is the necessary condition for the existence of any other system; while the functioning of the system itself is impossible without the impulses of the nervous system.
At the same time, the knowledge of human body systems should also be explored in their connection with environment, which can help to understand the most important evolutionary mechanisms and their role in the life of modern people. For example, comprehensive understanding of an individual’s sexual conduct is not only about understanding the mechanism of reproductive system, but also about understanding human psychology, including the origin on particular body movements (Hugill, et.al., 2010). So, comprehensive knowledge of human body systems, their mechanisms, and evolution is a prerequisite for understanding life in all its fullness.
