respiratory system

  • Your respiratory system is made up of the organs in your body that help you to breathe. Remember that Respiration = Breathing. The goal of breathing is to deliver oxygen to the body and to take away carbon dioxide. The lungs are the main organs of the respiratory system.The ease with which oxygen and carbon dioxide can pass between air and blood is clear from this electron micrograph of two alveoli  and an adjacent capillary from the lung of a laboratory mouse.Lungs & Respiratory System Basics.
  • Each day we breathe about 20,000 times. All of this breathing couldn't happen without help from the respiratory system, which includes the nose, throat, voice box windpipe and lungs. With each breath, you take in air through your nostrils and mouth and your lungs fill up and empty out. As air is inhaled the mucous membranes of the nose and mouth warm and humidify the air.
