There is nothing simple when it comes to biological systems. Engineer and physician Dr. Randy Guliuzza brings his expertise to bear on the human body, exploring multiple aspects of its complex inner workings. Engineers strive to design structures that are safe, readily buildable, achieve maximum results with minimum resources, and withstand a reasonable amount of abuse without breaking. Systems of the human body show all of these features - at levels that should evoke the greatest respect, and indeed adoration, from every engineer for the finest Engineer of all, the Lord Jesus Christ. The human body is an amazing example of biological engineering, with a myriad of interconnecting systems that produce unique capabilities. Join engineer and physician Dr. Randy Guliuzza as he explores the astounding complexities behind how the body works, from the growth of a baby to skin's built-in sun protection to how cells are supplied with energy and much more.
