A review of Some Physical principles on human body

Abstract

physics in studding living system; there are no professional books in such topics. Physics of the human body looks at the several of physiological systems in the human body from physical point such as mechanics, pressure, fluid flow, light and sound. The thesis presents brief reviews of the importance of physical principles in the operation of the human body. The combination of the knowledge from biology and engineering can be used to understand the principles of biomechanics. The biological principles underlying different systems are introduced such as the respiratory system, cardiovascular system, auditory system and the vision system (the eye). These are followed by core description related to the fluid principles such as Newtonian fluid flow, sound physics, and physics of light. The review study includes the effect of gravity on fluids pressure, and fluid flow that represent how the body maintains body temperature through the mechanism of vasodilatation and vasoconstriction of blood vessels which in turn affect the flow rate of the blood. The relation between work and energy are reviewed in this thesis. Also on the other hand the physiological mechanism of hearing and balance, transmission of sound in the ear are described briefly on the basis of physical quantities. The thesis represent the brief review of basic concept of contemporary physics those are relevant to the life science. These brief reviews of concepts are recommended to be expanded in the near future for a full review book in the subject.
