This course is an understanding of the basic concepts of earth/life sciences which contains an introduction to life sciences which is an intersection with mechanical engineering which is related to mechanical systems in animals and humans. The discussion begins with understanding the concept of life science structure, an introduction to cells from chemical and biological aspects, then continues with a discussion of bioenergy and metabolism. The discussion of life sciences is deepened by discussing material on mechanical systems in animals which includes: animal control systems, thermoregulation, homeostasis, biomechanics, animal locomotion, and scale effects. Then regarding the natural environment which discusses food and agriculture, environmental conservation, air and water. The next discussion discusses mechanical systems in humans, namely anatomy and physiology, human biomechanics, biomaterials, bioinstrumentation and biosensors.
