Biofizik

• Biophysics


  The field that applies the theories and methods of physics to understand how biological systems work
• What biophysics has been critical to understanding


  • The mechanics of how the molecules of life are made
  • How different parts of a cell move and function
  • How complex systems in our bodies—the brain, circulation, immune system, and others— work
• Biophysics is a vibrant scientific field where scientists from many fields including math, chemistry, physics, engineering, pharmacology, and materials sciences, use their skills to explore and develop new tools for understanding how biology—all life—works
• Human body as a machine

  The combination of impellers, gears and assemblies of various parts to transform any type of energy into another energy, to function or to create an effect by making use of a certain power
• Regulating units of the body

  • Muscles
  • Pumping System
  • Heart
  • Vessels
  • Waste disposal system
  • Enterohepatic system
  • Heat regulating system
  • Sensors
  • A center in the brain
  • Alarm system
  • Amygdala in the brain
• Mechanical advantage


  • The application of mechanical advantage applies to the musculo skeletal system
• Types of levers in the human body

  • First class lever
  • Second class lever
  • Third class lever
• Almost all movable joints function as third class levers
• Human heart


  • The most efficient of all pumping systems
  • Begins working in utero
  • Pumps day and night without cessation till the end
  • Requires a great deal of energy
  • Most efficient even at the time of its greatest stress
• Enterohepatic circulation of bilirubin

  Waste disposal system
• Heat regulation system
• Can human brain be considered as a computer
