The general function of the respiratory system is to allow oxygen exchange in all parts of the body. Oxygen is supplied to the blood and it is delivered that way. The respiratory system does this through breathing which involves taking in oxygen and exhaling carbon dioxide.

Parts of the respiratory system include:

  • Lungs-oxygen is taken into the body and carbon dioxide is breathed out-the red blood cells pick up the oxygen and carry it to all other cells that need it
  • Trachea-filters the air we breathe
  • Bronchi-two air tubes that branch off the trachea-air is carried directly to the lungs
  • Diaphragm-dome shaped muscle at the bottom of the lungs-main muscle used in breathing

There are many diagrams and photos on the internet that you can use in your powerpoint. I posted a link below that has a good diagram. You could also use Google Images.
