Anatomy & Physiology

Send by email

In this course, students will examine body form and function in a wide range of plants and animals. An evolutionary approach will be used to demonstrate how anatomy relates to function, including comparisons of specialized features in organisms adapted to different conditions. The class concludes with an extended dissection activity involving a variety of invertebrates and vertebrates that allows observation and comparison of all the system studied throughout the semester. This elective builds upon concepts introduced in Science I and II (for details, see the units below) and seeks to increase the depth and complexity of understanding of how the human body works, and how it evolved to its current form.
