Respiratory System and digestive system

By Roque and Justin

The respiratory system Is the system that let's you breath in and out.  The main organ in this system is the lungs.  

Lungs

The air goes in through your mouth or your nasal cavity and then down your tranchea then seperates into the two lungs through the brancites.  The  oxegen that the lungs get they use for cellar respiration.  Then the lungs send out carbon dioxide.

The long tube is the esophoges. It moves food from the mouth that breaks down the food to the stomack.  The stomack breaks down the food more then sends it to the small intestine. The small intestine gets all the energy and nutrients from the liquids you drink them the large intestine gets the nutrients from the food and the you get rend  of the waste.
