Biology 109 - Anatomy & Physiology I


Biology 109-110 (each course 3-2-4) Anatomy and Physiology I & II: Human physiology and biochemistry are studied systematically in lectures while anatomy is stressed in laboratory experiences requiring extensive dissection. This two semester sequence follows the recommendations of the Human Anatomy and Physiology Society. Biology 109 is designed for students who have had high school biology and chemistry within 10 years or who have passed Biology 106. Biology 109 is a prerequisite for Biology 110.
