Are you interested in learning more about living things, or perhaps beginning to train for a career in the healthcare or medical professions? This course will help you understand the structure and function of the human body at the level of your tiniest living components—your cells. You'll also learn about DNA—what it is, what it does, and even a little bit about how forensic scientists use it to solve crimes. The knowledge you'll gain from this course is essential to understanding the fundamental causes of human disease, and will prepare you for more advanced courses in human anatomy and physiology. As you explore each topic, you'll have lots of opportunities to deepen your understanding and relate what you're learning to your own life. When things get complicated, you'll have the guidance you need, so you won't get overwhelmed by the details. By the end of the course, you'll have a better appreciation of the fundamental characteristics of living things as well as a solid foundation in the biology of human beings and the biological and medical sciences.
