This second installment of Advanced Anatomy and Physiology continues to lay the groundwork for college-level medicine and life science courses. We further our understanding of the function and structure of the cardiovascular system, including hands-on practice with blood pressure, pulse points, and PQRST complexes. From there, we explore how muscles work with the nervous system to contract and do work. Our inquiry includes a comparative analysis between the muscles of a mink and the muscles of a human as we learn to categorize almost 200 of the 600 muscles we use every day. For our final topic, we investigate the science of the brain and nervous system to better understand how we process information, respond to threats, and make decisions.
