Digestive System Essay

Digestive System After dissecting the rat, we learned that the rat’s body has many complex systems. To begin, the digestive system contains a group of organs that work together to convert food taken in from the body and converts it to energy and basic nutrients to feed the cells in the body. The digestive system includes the mouth, pyloric valve or sphincter, caecum, small intestine, colon (large intestine), duodenum, retrum, and stomach. The salivary glands, liver, and pancreas are glands that

alimentary canal is where the digestive system takes place; it has different components in order for food to be thoroughly processed. The digestive system is composed of an enteric nervous system and has four layers of tissues; the mucosa, submucosa, muscularis externa, and serosa. Food enters through the mouth and passes through the esophagus, stomach, small intestine, and the large intestine before exiting the body through the anal canal. This occurs within the digestive system in four main steps; ingestion

When choosing between what system to write about, I thought the digestive system would be a good topic because food is probably one of my favorite things, not only cause it tastes good but because it gives me the energy to do all the things I need to do throughout the day. We talked in class about how you should always get the nutrients from food and never from supplements, which I’ve always tried to do. So, what is the digestive system? The digestive system is an assortment of organs that performs

The digestive system has the function of digestion and absorption. This means that the digestive system breaks down food into small molecules that will be absorbed and used by the body. But this process can only be completed with the help of multiple organs – the esophagus, the stomach, and the colon, to name a few. First is the mouth, where the salivary glands, tongue, and teeth are located (fig 2). The salivary glands produce saliva, which helps break down food. The teeth cut and grind the food

The Digestive system: The stomach related framework is comprised of the gastrointestinal (GI) tract—likewise called the stomach related tract—and the liver, pancreas, and gallbladder. The GI tract is a progression of empty organs participated in a long, bending tube from the mouth to the butt. The empty organs that make up the GI tract are the mouth, throat, stomach, small digestive system, internal organ—which incorporates the rectum—and butt. Sustenance enters the mouth and goes to the rear-end

The Digestive System The premise of the digestive system is to turn food into energy and get rid of waste. This system has two main functions, digestion and absorption. One of the system’s major parts is called the digestive tract or alimentary canal. The digestive tract is an ongoing tube that has two openings. One opening is the mouth and the other aperture is the anus. The alimentary canal consists of the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. This canal also

What the digestive system does The digestive system is when the body does to break down food. Firstly, it enters the mouth and is broken down by the teeth of the animal and saliva. Then it travels along the oesophagus to the stomach. Then in the stomach for further breaking down, it is broken down by hydrochloric acid and enzymes. The acid breaks down bacteria and the food material into smaller molecules. Once this is complete it then moves onto the small intestine. Enzymes are secreted from the

Nutrition BIO-151 Chapter 3 Digestion Cheyenne De Jong October 8, 2017 The digestive system is a group of organs that work together. It is responsible for taking whole foods and turning them into energy and nutrients to allow the body to function, grow and repair itself. Today, I will explain how the digestive system performs this unique process. I’m having a loaded tuna sandwich with lettuce, tomato, cheese and mayonnaise. The bread of my sandwich is mostly carbohydrates. Carbs are the sugars

D2 how the digestive system, cardiovascular system and respiratory system all link together How the digestive system works? Food moves through the GI tract. Digestion starts in the mouth with chewing and finishes in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them

The digestive system is a severely underrated part of the human body. For most people, the digestive system is just something that gives them diarrhea after they eat poorly. Little do they know, that the digestive system is the key part to fueling our bodies. The digestive system is how you break down and absorb much needed nutrients. This is how we “fuel” our body. Our body breaks down the food we eat into manageable pieces, and then we are able to absorb it into our bloodstream so that it can be
