This lecture-based course examines principles, patterns, and mechanisms of biological function from the level of cells and tissues to the whole organism. Emphasis is placed on relationships between structure and function, mechanisms of regulation, control and integration, and adaptation to the environment. The primary focus is on vertebrate systems. Laboratories provide practical experience in measurement and experimental elucidation of physiological phenomena and functional analysis of gross structure. Evaluation will be based on hour exams, laboratory practicals, and a final exam. Prerequisites: Biology 101 and 102. No enrollment limit (expected: 60). Satisfies distribution requirement in major.
