The Digestive System is always working throughout the day and night.
It is a complicated system. There are four steps to the Digestive Process.
The first step of the process is when you first take a "scrumptious" bite of
food into your mouth. Believe it or not, it starts before you even take that
bite. After you take that bite, the food gets chewed into tiny bite-sized
pieces. The teeth start chewing and breaking the food into smaller pieces
and the saliva helps the food to start getting even smaller.
....The second part of the process is when the food gets swallowed and
travels through the esophagus. It gets even smaller when the saliva in the
esophagus makes it into microsized pieces. Then the food travels to the
stomach.The stomach, with help from the liver and the pancreas, break
down the food to even smaller pieces and then it gets delivered to the small
intestines. Before the food goes to the small intestines, the kidney’s job is
to remove harmful substances. If there are harmful substances, like poison
or lead, the kidney absorbs the foul substance.
....The third part of the process begins. The food gets to the small
intestines and it starts to travel inside the small intestines. The small
intestines is as long as a continuous rope. It is just squished inside your
body and has a lot of wrinkles. On our trip to the Bodies Exhibition in
lower Manhattan, we learned that if you were to steam-roll the small
intestines, it would be as long as 100 feet!! Imagine that!
....When the food finally reaches the large intestines, it starts to go
around and around and prepares for the final process of elimination. The
fourth and final process is the "restroom break". After your food gets
digested, you have to use the restroom. That is the waste that your body
doesn’t need. The bladder is where your urine waste is stored.
.... That is the digestive system's function or how it works. The digestive
system is a very complex system of the human body.
