  • "The Difference Between Respiration and Breathing Believe it or not 'respiration' and 'breathing' don't mean the same thing! Although some older books on physiology may still use terminology such as 'external respiration' and 'internal (or cellular) respiration', in most present-day textbooks, RESPIRATION refers to the process of oxydation of food to release energy in cells, while BREATHING (or ventilation) refers to the constant movement of the respiratory medium over the respiratory surface. However, terms like 'respiratory system', 'respiratory surface' and 'respiratory centre', in which 'respiratory' actually means 'breathing', are still commonly used; this usage is a common source of confusion to students."

  • Sometimes we use the terms breathing and respiration to mean the same thing, but they actually are distinct processes. Breathing is the process of moving oxygen-rich air into and out of the lungs. Respiration refers to how the cells of the body use oxygen to create energy and how they exhale carbon dioxide that is a waste product of this process. The lungs have to work continuously because the body cells are constantly using up oxygen and producing carbon dioxide. Unlike the heart, the lungs have no muscle tissue. Instead, muscles in the rib cage and the diaphragm do all the work of lifting the ribs upward and outward to let the air in, and then relaxing to force the air out. Breathing is defined as “the exchange of gases between the cells of an organism and the external environment” While it is true that the physiology of breathing is complex and extensive, the process of getting those gases from the environment to the cellular level of the body can be observed and understood by the general, non-medical population. Understanding the mechanics of breathing can facilitate the doing of breathing exercises for general relaxation, pain management, general health promotion and the increase of energy. Two very simple concepts comprise the act of breathing as defined above. They are ventilation, or bringing oxygen into the lungs and circulation, or transporting the oxygen all over the body, to where it is needed. Respiration is the process used in all living things for gaining energy. Energy is needed for keeping the vital organs working and generally staying alive. It is also needed for moving muscles. Keeping a constant body temperature is important to. Cell division, reproduction and other important processes in the body all need energy to work. Respiration is not just a gas exchange, oxygen for carbon dioxide. Oxygen is the one critical part of a larger process and carbon dioxide is simply a by product of the process. Cellular respiration a complex series of chemical reactions where sugars are broken down to release energy by the use of oxygen. (Gottfried, 1993). The key is not the gases that are released, but the energy. The next concern is who or what does cellular respiration. It is commonly thought that organisms with some form of respiratory system can respire and that is true, animals undergo cellular respiration, but we are not alone. Because every living organism is composed of cells, and all cells need energy to function, then every organism must carry out some form of cellular respiration. http://en.wikibooks.org/wiki/GCSE_Science/Breathing_and_Respiration http://lsa.colorado.edu/essence/texts/lungs.html
  • breathing is simply, inhaling and exhaling. but what people dont know is that it is possible to respire with out breathing, this is called anaerobic respiration, in this case case all we need is glucose which produces lactic acid and energy.in aerobic respiration, we need oxygen and glucose which forms carbondioxide, water and energy
  • breathing is is also called ventilation, this is just the inhalation of air and the exhalation of air. on the other hand respiration is a chemical reaction that occurs in all living things, during this process sugar, or should i say glucose is used to produce energy for our body to function
  • breathing is taken in oxygen(inhalation) and given out carbon dioxide(exhalation) while respiration is the use of oxygen to burn food substances in the body to produce energy to the body cells and tissues.
