The Digestive System: How it Works

Avery Blau

What happens

Have you ever wondered what happens to your food after you eat it? As you may know,it goes through a series of organs called the digestive system. Okay pretend you have a nice big plate of Kentucky Fried Chicken,yum! So ,you bite into a big,juicy piece .Your teeth and tongue help break it down.Guess what so does your spit! Salivary glands make the saliva, or spit, and softens your food so it's easy to chew. When you swallow ,you're pushing the food down the pharynx to the esophagus which slowly pushes your food to the stomach. As soon as the chicken reaches the stomach ,a powerful acid called bile attacks it. Bile breaks down food to a pasty/liquidy mush. After the food sits in the stomach for two to three hours, it transfers to the intestines.

What happens

The first intestine is the small intestine( 6 meters long). The small intestine is where the food mixes with enzymes that comes through small tubes that are leading from the liver and pancreas to the stomach. Next comes the large intestines(1.5 meters long). Absorbs vitamin and water into the blood stream . The last part of the digestive system is the rectum and anus. that is where the waste leaves the body.

The digestive system may sound gross but it is one of the most important systems in the body. Without it our blood wouldn't be healthy and we wouldn't be as strong as we are. Next time you're playing a sport or playing with a friend ,think about how your body converted food into energy.
