The Journey of Food Through the Body

Ever wondered how your body miraculously turn your food into nutrients and energy that your body can use? Here are step by step process on how our human body digest, or turn food into useful nutrients our body could use.

Step 1: Mouth

Digestion takes place right after your first bite of food. Chewing breaks up the food to aid the digestion process. The food then mixes with saliva to help go down the Esophagus, as well as break down the food.

Step 2: The Esophagus

The esophagus is a tube that connects your throat to your stomach. As food enters the esophagus, salivary glands releases saliva to make it easier for food to travel through. It uses contractions, called peristalsis, to transport food to your stomach. A high pressure exists in the connection of the stomach. This is to prevent the food from going back into your esophagus.

Step 3: The Stomach

Stomach is used to hold food and at the same time, mixes and grinds the food you’ve eaten. The walls of the stomach are muscular and contracts to further break down the food. The st...

    Esophagus: Esophagus is a long straight tube which connects the pharynx to the stomach. Once the food has been reduced to a soft mush, the tongue pushes it to the throat which leads to a long straight tube called esophagus. The esophagus squeezes the mass of food with rhythmic muscle contraction called peristalsis which then forces the food to the stomach.

    Mouth- Digestion begins in the mouth. Physical actions, such as chewing, breaks food into small parts so it can be easily digested. Next, salivary glands secrete an enzyme called saliva to mix with food to start the breaking down of carbohydrates (WebMD (2).) From the mouth, food travels to the pharynx, or throat, by swallowing,

    ...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.

    Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.

    During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the

    Now the Cheetos have entered the stomach. The process of breaking down carbohydrates has already begun in the mouth and now more chemical and mechanical digestion will take place in the stomach. Once the bolus has entered the stomach, it mixes with gastric juice, starts protein digestion, and absorbs a limited amount. Here the chief cells secrete the inactive enzyme pepsinogen and the parietal calls secrete hydrochloric acid. When mixed together, they create pepsin. The pepsin works to breakdown the two grams of protein present in the Cheetos. Hormones are also present in the stomach and aid in the digestion process. The hormone, gastrin, increases the secretory activity of gastric glands. In the stomach, some salt from the Cheetos is absorbed through the wall. The Cheetos that entered the stomach has no...
