Analyzing the mechanism responsible for changes in the circulatory system which develop in microgravity depends on the results of medical examinations during long-term space flights. The primary component involves the elimination of gravity-related deformities and mechanical tension among body structures responsible for modifying gravireceptor impulse inputs, fluid redistribution and functional load reductions in the muscular system. This causes the circulatory system to change. The influence of these factors on the circulatory system is substantiated through theoretic-physiological fundamental principles during long-term space flights.
