Biomechanics is the application of mechanical principles on living organisms. This includes bioengineering, the research and analysis of the mechanics of living organisms and the application of engineering principles to and from biological systems. This research and analysis can be carried forth on multiple levels, from the molecular, wherein biomaterials such as collagen and elastin are considered, all the way up to the tissue and organ level. Some simple applications of Newtonian mechanics can supply correct approximations on each level, but precise details demand the use of continuum mechanics.
The study of biomaterials is of crucial importance to biomechanics,for example,the various tissues within the body´s organs, such as skin, bone, and arteries each posses unique material properties. The passive mechanical response of a perticular tissue can be attributed to characteristics of the various proteins, such as elastin and collagen, living cells, ground substances such as proteoglycans, and the orientations of fibers within the tissue. For example, if human skin were largely composed of a protein other than collagen,many of its mechanical properties, such as its elastic modulus, would be different ontinuum mechanics.
