Do you know what you're made of? The answer is CELLS- about thirty TRILLION of them- all working together to form one awesome human being: YOU. The tiniest building blocks of life are crammed amongst the pages of this book, waiting to be discovered. From individual cells to complex systems, discover how your body moves, grows, breathes, senses, thinks and feels. Find out why you get butterflies in your stomach, how your brain is more complex than the most powerful computer, and that you are home to more bacteria cells than there are stars in the Milky Way.
