Skeletal---> Digestive The skeletal system and the digestive system are connected because the digestive system provides the skeletal system's parts with glucose. When we eat food, the food goes in through our mouth. In our mouth, starches begin to be broken down by our saliva. The food then goes down our esophagus, and into our stomach, where food id churned and mixed, and protein begins to be digested with enzymes and acid in the stomach. In the small intestine, food is completely broken down and nutrients are absorbed, and in the large intestine, water is absorbed and leftovers are stored until they are excreted out the anus. The small intestine is the key part to this process, however. The small intestine is where nutrients are absorbed- nutrients like glucose. The glucose is picked up by millions of finger-like structures on the inside of the intestine called villi. Inside the villi, there are little blood vessels which the glucose molecules diffuse into. From the capillaries, the molecules are carried in the bloodstream to places where they are needed- including bones. The bone cells use the glucose along with oxygen to create energy for itself.
The skeletal system and digestive system are literally connected in the mouth as well. Along with saliva breaking down starch in the mouth, we chew our food so that the food pieces become smaller and easier to digest. We can only chew because of jaw movements (and teeth, of course, but that isn't the point I'm trying to make)- and what makes up our jaw? Our "jaw bone"- the mandible.
