From what I have learned from this week’s reading and watching the animated digestive tract. Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestion process also…
Loops back and forth upon itself many times. Split into the Duodenum, Jejunum, and the Ileum. Processes about 2.5 gallons of food, liquids and bodily waste every day (nutrients absorbed by villi)…
The glands in the stomach lining produce stomach acid, called gastric acid, and an enzyme that digests protein. The pancreas produces a juice containing several enzymes that break down carbohydrates, fats, and proteins in food. The pancreas delivers digestive juice to the small intestine through small tubes called ducts.…
We all love to eat. I remember my parents used to tell me that in order for my food to digest properly, I would have to chew it one hundred times on both side to make it small as possible. They said that if the food was smaller it could digest quicker and easier. But most people do not know what happens to their food after they have chewed it up and swallowed it. Some may think that right after the food is swallowed, it goes straight to the stomach. The purpose of this essay is to discuss the path food follows as it goes through the digestive system.…
The digestive system is the physical ad chemical breakdown of food. Following ingestion, food and fluids are processed by the digestive organs so that nutrients can be absorbed from the intestines and circulated around the body. Any residue of food that is not digested is solidified and eliminated from the body in the form of feces. (P.207)…

During his or her lifetime, the average person eats his/her way through at least 20 tons of food. Meats, vegetables or sweets - whatever your diet, that’s 40,000 pounds! Our digestive system works to turn this enormous amount of food into substances that the body can use for energy and for growth and repair. But what actually happens to these foods once they enter our bodies? How does the body process each tasty bite and harness the power locked in the food?…
The small intestine absorbs food molecules which are then passes onto the bloodstream and taken to…
The absorbed substances are then moved through the blood vessels to different organs of the body where they are used to build complex substances, such as the proteins required by our body. The food that remains undigested and unabsorbed passes into the large intestine where very small amounts of nutrients are absorbed. The food then exits your body through the rectum or anus.…
Once I have taken a bite out of my delicious favorite meal, the digestive system gets to work. It all begins in the mouth, chewing the food small enough to swallow. Salvia is squirted into the food to moisten and soften the food. Salvia contains enzymes, which break down the starches in food. Once the tongue forms the food into a ball to be swallowed, it is sent down the pharynx. The pharynx contains sphincters that help keep your food down once you swallow. Next, it makes its way to the esophagus, which is simply a transportation tube from the mouth to the stomach. It then reaches the stomach, which uses chemicals to make the food particles tinier. These chemicals are called gastric juices and include hydrochloric acid and enzymes. Once the stomach mixes with the chemicals, it is formed into a cream-like liquid called chyme. The gallbladder takes over from here hitting the food with more chemicals, one of them called bile. Bile is mixed with our food breaking down the fat into droplets, which will supply us with energy later on. From there, the pancreas uses digestive juice to break down…
Gastric juice in the stomach begins protein digestion with peristalsis continuing to mix the food, which eventually forms a fluid called chyme that travels to the small intestine. The chyme is absorbed into the intestine with some of the nutrients being absorbed into the bloodstream with water and minerals being reabsorbed into the blood in the colon, while the waste is…
Materials that are absorbed in small intestines are transported directly to the liver and goes through a detox before it enters general circulation…
Chemical breakdown results from the action of digestive enzymes and other chemicals acting on food as it passes through the GI trac…
