Ever wonder why you yawn? Low oxygen levels trigger yawningafter a period of shallow breathing. A yawn forces oxygen rich airinto your lungs where it can be passed into the bloodstream. ThisCD-ROM from Dorling Kindersley is filled with answers to many whyand how questions. Why do we have reflex actions and how do theywork? Why do you blink? How do we swallow? Where does energy comefrom? How are babies created and formed?
The more than forty-two articles are divided into threesections: the “Body Machine”, the “Body Organs”, and the “BodySystems”. The “Body Machine” provides a graphical tour of the humanbody with the largest number of animations. The “Body Organs” showshow body organs fit together inside the body. Organs are shown intheir proper location and the student can remove them one by one tosee the underlying organs. Text is available if the student wishesto find out more about a particular organ. The “Body Systems” isdivided into the ten different body systems: skeletal, muscular,circulatory, digestive, urinary, nervous, reproductive, lymphatic,hormonal, and respiratory.
Specific topics can be accessed by clicking on the “A-Z” indexbutton. Click on any item in red for additional information. The”Options” button is the downward arrow and provides copy and printcapabilities. It also has a sound on/off option. I recommend havingthe sound set to off. When the sound is on, annoying noises occurwhenever a window is opened or closed as well as when sections ofthe body are “exploded.”
Having the sound off does not affect audio statements when a newsection is opened. Neither does it affect pronunciation and audioduring animations. Both male and female voices are used for audioportions.
Some may be upset by the explicit discussion and graphicrepresentation of the reproductive system, but it is done in anexplanatory, factual tone.
Special Features
Animated sequences such as the ones showing what happens to ourheart and lungs when we exercise, how the blood circulates, whathappens when we chew and swallow, and how the digestive systemworks are indispensable to visual instruction. Explaining the fourdifferent types of joints used by the human skeletal system formovement is made easier by use of such animated illustrations. Itdefinitely is a case where a picture is worth a thousand words.
