Informational Essays On The Digestive System

The purpose of an informative essay, sometimes called an expository essay, is to educate on a certain topic. It is not for giving an opinion or convincing someone to do something or change his beliefs. In addition to being informative, it needs to be interesting.

Structure of an Informative Essay 

The basic structure of an informative essay is very simple. It needs to have a beginning, middle, and end.

  • The beginning needs to present the topic and grab the attention of the audience. It needs to include the focus sentence for the entire essay.  
  • The middle will be the main bulk of the essay and it will contain all the important facts that you are covering. This is where the audience will get their questions answered. Remember to answer these questions: who, what, where, when, why, and how. 
  • The end is a conclusion where you will summarize the essay. It should spur the reader or listener to learn more about the topic.

The Beginning

Here is an example of the beginning of an informative essay: 

As you are listening to me, you might not think that today is the day that you will save a life. It is quite easy to save a life any day and it only takes a little bit of your time. I’m not talking about being a paramedic or fireman; I am talking about donating blood. 

The Closing

Here is an example of a closing: 

So that now you know how easy it is to donate blood, it’s time to take action. After all, you have plenty of blood, so why not share? When you do, you will feel good about yourself and you will save a life.

Subjects of Informative Essays

Informative essays, sometimes called expository essays, can be used for many purposes. They can compare viewpoints on a controversial subject as long as they don’t include the author’s opinions. They may analyze data, like in a cause and effect situation, or educate the audience on ways to do something, like solving a certain kind of problem.

For example:

  • An informative essay might explain the pros and cons of the death penalty, using statistics on crime rate reduction as a pro and statistics on innocent men being found guilty as a con. 
  • An informative essay might analyze whether lack of education is a cause of homelessness by using statistics and information about the educational attainment of homeless men and women. 
  • An informative essay might educate the audience on how to open a bank account.

Informative Essay Titles

  • Understanding the Link Between Cholesterol and Heart Disease
  • How to Buy a House
  • Understanding Your Credit Score
  • Defining Poverty in the City of Chicago
  • The Health Benefits of a Vegetarian Diet

  • The Causes of Global Warming
  • Reducing Carbon Emissions with Alternative Fuels
  • Cost Savings of Hybrid Vehicles
  • Understanding Geothermal Heating and Cooling
  • Why Cleaning Your Ducts is Important
  • Qualifications of Contractors
  • How to Get your Commercial Driver's License

Steps in Creating an Informative Essay 

Most of the work on an informative essay is done before you actually sit down to type. Here are the general steps to take:   

  1. After you have chosen the topic, you will need to research and gather all the pertinent details on that subject. You need to ascertain what you already know about the subject and then decide what you would like to know.
  2. You will need to make a list of the important facts and then list the main steps in your paper. Make sure all your facts are accurate. You will need to write a topic sentence for each fact and write a focus sentence (thesis statement) for the entire essay.
  3. Create an outline that will organize your facts in a logical way. Then you will be ready to make your first draft.
  4. Editing is an important step for any writing project. Reading your essay out loud will help you notice places where the writing is awkward or unclear. If possible, have someone else read it and give you their ideas for improvement. Of course, you will need to pay attention for grammar, punctuation, spelling, capitalization, and other errors.

An informative essay is the best way to explain something that is complicated...in an uncomplicated way.

The Human Digestive System Essay

772 Words4 Pages

When we eat, the nutrients and energy we need in order to function have to be extracted from food and absorbed into the body. The process responsible for this is known as digestion. The human digestive system has to be able to process our omnivorous feeding habits and diet, and has adapted this to function at an optimum level and is controlled by our autonomic nervous system by the brain.
The digestive system is a collective of automated processes and organs, enzymes, secretions, some accessory organs and a pipework (or tube) that starts at the mouth and ends at the anus, known as the alimentary.

The digestive system is a collective of automated processes and organs, enzymes, secretions, some accessory organs and a pipework (or tube) that starts at the mouth and ends at the anus, known as the alimentary. The processes that take place along the alimentary canal are how we take in these various nutrients, differentiate what that body can use for survival and function, and what it does not need or are surplus to requirements. This surplus food is passed through the alimentary canal at the opposite end and is excreted as waste.
The entire digestive process starts at the mouth. As we eat and take in food, the chewing action in the mouth uses the jaw, muscles and teeth to grind, mash and break up the solid food masses into smaller particles. Food is moistened by saliva, a secretion released from small ducts within the mouth. An enzyme within the composition of saliva called Amylase, works to dissolve some food particles and break down starchy foods, turning them into glucose. The advantage to this reduction in food size, all along the digestive tract, is to maximise surface area and make
