    The Human Body

    Even though the body is composed of intricate systems all functioning together, it is best to focus on one aspect at a time. Here you The Human Body will find a series of articles and activities dedicated to just that. Whether you want to know more about the brain, the heart, your digestive system, basic anatomy, or even your system of cells - there is something here for every learner and every skill level.

    Did you know that there are more than 22 organs in the human body? Or that the stomach can expand to hold up to two liters of food? Do you understand the difference between controllable and uncontrollable factors which influence the health of your heart? These human body study guides cover a wide variety of topics and systems. We are not focusing on muscles and nerves here (although don't skip the article on connective tissue) but more on the body's biochemistry, including the way it handles germs and viruses. This compilation of articles includes homework help, test preparation and extracurricular information.

    Organs & Body Systems

    Eating & Digestion

    While the digestive process does not fall under the classification of human anatomy, these articles will help students understand some of the basic biochemical functions that are bodies undertake.

    The Cell

    Cells are the basic building blocks of the human body. How are cells differentiated? Did you know that neuron cells carry electrical charges? Learn more about the cells' existence, the different types of cells and how they operate to perform all of your body's functions.

    About the Brain

    The human brain is arguably the most complex and intriguing part of the human body. Weighing on average around 3 pounds and containing over one hundred billion nerve cells, the brain is central to the body's nervous system and all of its functions. Do scientists know everything there is to know about the brain? Absolutely not! What we have uncovered, however, is a basic understanding of the parts and what they control. You can learn more about that by investigating the information offered in the following articles:

    Projects Related to the Human Body

    Of course, learning is one of the brain's main functions, and it does so by gleaning information from more than just lectures and charts. What are the parts of the brain, and what does each area do? Here you will also find what you need in order to complete a project related to the human body, and its components. Or, you prefer a hands-on learning experience as you study. The projects offered below cover the human body, the power of the brain and cool ideas on making DNA models. These project ideas can be easily adapted for use at any level. They also offer the opportunity for students to take a closer look at specific topics related to human body study.

    Once you have a better understanding of the individual systems of the human body, you can better understand and appreciate how they are inter-connected and rely on each other to make the body work! Whether by chance, or by design, the human body and its intricacies invoke a sense of awe.

    This compendium of resources offers the teacher a variety of lesson plans for teaching the class as a whole about the human body. The teacher can also assign individual students or groups of students to work on projects for each of the topics in this guide. You can utilize the articles in this guide with a resource such as, which is part of and offers many freebies to teachers, to integrate some hands-on study into their lessons.
