The modern concepts of osseous tissue changes in spaceflight

This paper examines possible physiological mechanisms responsible for the loss of bone tissue associated with spaceflight. The authors apply the philosophical theories of V.I. Vernadsky to develop some models or algorithms of the body's functional systems and how they relate to bone loss. Loss of bone mineral content is discussed with relation to the functioning of other systems and organs, such as the liver, lungs, kidneys, endocrine system, etc. Coefficients of correlation are presented and discussed.
