Biological fluid mechanics, or biofluid mechanics, is the study of both gas and liquid fluid flows in or around biological organisms. An often studied liquid biofluid problem is that of blood flow in the human cardiovascular system. Under certain mathematical circumstances, blood flow can be modeled by the Navier–Stokes equations. In vivo whole blood is assumed to be an incompressible Newtonian fluid. However, this assumption fails when considering forward flow within arterioles. At the microscopic scale, the effects of individual red blood cells become significant, and whole blood can no longer be modeled as a continuum. When the diameter of the blood vessel is just slightly larger than the diameter of the red blood cell the Fahraeus–Lindquist effect occurs and there is a decrease in wall shear stress. However, as the diameter of the blood vessel decreases further, the red blood cells have to squeeze through the vessel and often can only pass in a single file. In this case, the inverse Fahraeus–Lindquist effect occurs and the wall shear stress increases. Now that you understand the basics of joint movement, let’s get into the optimal way to move and place forces through your joints (i.e., EXERCISE!)

Because the body consists of linked segments, the amount of force in the impulse applied by the distal segment is essentially the sum of the force from all the joints used. More joints contributing and more force from each joint increase the applied impulse. All joints that can contribute should contribute, and the force from each should be as much as is needed. If a joint is not used, or contributes less than its potential, the applied impulse is less. The visual key is the number of joints moving, with the important factor the rate at which they move. Faster joint action indicates more muscle force contribution and produces a greater applied impulse. The principle of continuity of joint forcesHatze, Herbert (1974). "The meaning of the term biomechanics". Journal of Biomechanics. 7 (12): 189–190. doi: 10.1016/0021-9290(74)90060-8. PMID 4837555. There are other directional terms to help describe the position of the body segment relative to the anatomical position eg In 1543, Galen's work, On the Function of the Parts was challenged by Andreas Vesalius at the age of 29. Vesalius published his own work called, On the Structure of the Human Body. In this work, Vesalius corrected many errors made by Galen, which would not be globally accepted for many centuries. With the death of Copernicus came a new desire to understand and learn about the world around people and how it works. On his deathbed, he published his work, On the Revolutions of the Heavenly Spheres. This work not only revolutionized science and physics, but also the development of mechanics and later bio-mechanics. [19]

The study of biomechanics ranges from the inner workings of a cell to the movement and development of limbs, to the mechanical properties of soft tissue, [7] and bones. Some simple examples of biomechanics research include the investigation of the forces that act on limbs, the aerodynamics of bird and insect flight, the hydrodynamics of swimming in fish, and locomotion in general across all forms of life, from individual cells to whole organisms. With growing understanding of the physiological behavior of living tissues, researchers are able to advance the field of tissue engineering, as well as develop improved treatments for a wide array of pathologies including cancer. [23] [ citation needed] Strength training is the workout that most of us are accustomed to, where you work your muscles under load to build up your muscle mass. The key for strength training is that extra load: added weight or tension introduces a level of resistance to your workout, and the muscle mass develops as your body repeatedly learns to overcome that resistance. Anything that adds extra weight or resistance to your workout likely constitutes some form of strength work (i.e., deadlifts, bodyweight exercises, banded resistance exercises). a b c d e "American Society of Biomechanics» The Original Biomechanists". www.asbweb.org .

Generally this study involves complex geometry with intricate load conditions and material properties. The correct description of these mechanisms is based on the study of physiology and biological interaction. Therefore is necessary to study wall mechanics and hemodynamics with their interaction. Take your muscles, for example. At their core, their primary function is to simply contract and relax, but that simple action alone powers multiple facets of our movement (like flexion and extension at our joints). But muscle contraction also leads to other vital, physiological functions like oxygen consumption or digestion. Perhaps it’s not something everyone can answer immediately, but it’s certainly something people have asked lots about. And rightfully so — the world of biomechanics is vast and complex, and there’s plenty to explore when it comes to truly understanding what it is and how it plays a role in our day-to-day lives.
