       The digestive system uses these following organs. Small intestine, large intestine, mouth, stomach, and esophagus. The function of the digestive system is to eat food then break it down into energy we can use. The small intestines job is to absorb most of the nutrients. The large intestine absorbs the water. The digestive system starts in the mouth. The stomach breaks down the food even more with acade. The esophagus takes the food to the stomach. These two help the digestive system the liver and the bull balder. The liver absorbs fat and nutrients. The bull blader provides the bile.

                The respiratory  system is made up of the following organs. The trachea, the lungs, and the diaphragm. The function of the respiratory system is to get the oxygen we need and use it to break down sugars. The diaphragm contracts  to pull air in. The trachea is the passage that leads air to the lungs. Lungs hold the bronchioles where the alveoli live witch is where the  hole exchange occurs.

           The steps to making a organ system. The smallest is a cell I like to think of it as a brick. Then the next one is a tissue witch is lots of  cells working together to do a certain job. That is why I like to think of them as brick walls. Next is the organ these are a group of tissues working together to do a certain job. That is why I liked to think of them as one room. The last is the organ system witch is a group of organs that work together to do one  certain job. That is why I like to think of  them as a house.

sp2 developing and using models.

I constructed a physicall lung to represent and understand the lung. For rib cages We used a empty bottle. For a diaphragm we used a cut balloon and stretched it over the bottom of the balloon . Then we took a balloon and we shoved it into the bottle and we stretched the top and we put it over the top of the balloon. When you pulled on the diaphragm the balloon in side witch is your lungs would get bigger and when you let go the lung would get smaller.
