Follow Sabrina the Strawberry as she brings you on a exciting adventure, through your body. This comic explains the (about) 30 hour journey that food takes in your body. The process is an important one. Without the digestive system our bodies couldn't function. She will explain it inside and out, literally.
I begin my journey in the mouth, when a human consumes me.
I am now chewed up and broken down inside the mouth, with the help of saliva and teeth. While the tongue moves the pieces of food around, the food is covered in saliva to make it a smoother trip down the esophagus.
Once I am swallowed I pass through the pharynx (a tube) that sends me to the esophagus. The epiglottis is a flap that leads me down the right path to the stomach.The purpose of the esophagus is to send me to the stomach
Now in the stomach, I am being mixed with acid and enzymes, to be broken down even more. This is where mechanical digestion occurs. Chyme is also made here. It is a thick semi-fluid of partly digested food. I also make quick stops, to places like the pancreas which turn me into insulin and energy, and the liver, that secrets bile which aid digestion and break down substances. The bile is stored in the gallbladder. Next stop, small intestine.
Here in the small intestine, all the nutrients is absorbed out of me. The small intestine is lined with villi, which gives me a slippery route through the 12-16 foot long intestine. Smooth muscle contracts to help me move. This is called peristalsis. Chemical digestion occurs here. The tour is almost over.
In the large intestine the liquids in me are removed and the good bacteria break down nutrients. All of the good in me has already been extracted and I am all waste. Last stop, the rectum.
What is left of me is known as the waste. I am compressed and removed from the body. This is where I leave the body.
