(Also Chemistry 03.) How does the human body work, and what are the physical laws that describe and explain body functions? We will study circulation, respiration, digestion, acid/base regulation, excretion, and reproduction, while exploring chemical concepts such as molecular structure and phase behavior that make these phenomena possible. We'll ask how these functions are regulated by the nervous system and by hormones, and we'll explore electrical and chemical communication pathways at a fundamental level. Emphasis is on using mathematics and physical sciences to understand physiological functions. Three classroom hours and three hours of laboratory per week. Enrollment is limited to first-year students who are interested in science or premedical study, who are recommended to begin with either Mathematics 5 or the intensive section of Mathematics 11, and who are enrolled in a mathematics course but not in Chemistry 11. Instructor consent required. Fall semester. Professor S. George. Professor O'Hara.
