3D generated illustrations and medical imaging provide a close look at the body's forms and functions in physiology and anatomy, showing how the body works and its amazing systems and abilities.To understand our modern human bodies, this book first looks at our ancestors and how the evolution of Homo Sapiens shaped our anatomy. This gave us the ability to walk tall, create language, and make tools with our incredibly adapted apposable thumbs.Learn how we can see evolution in our DNA, and the functions of DNA. Read about the things you can only see with microscopes and other special imaging machines, like cell structure, motor pathways in the brain, and the inner iris.All these many parts work together to make the human body. The physiology of our body is written in clarifying detail. Learn about the organs and systems that operate within, such as the cardiovascular, digestive, and neural systems.
