Introduction to animal physiology
Marcus Clauss Clinic for Zoo Animals, Exotic Pets and Wildlife, Vetsuisse Faculty, University of
Zurich, Switzerland Bio122 2013
Science of organismal function from the subcellular level to the whole organism. Describes interactions of organism and environment. Quantifies rules for functions, linking them to physical
and (bio)chemical principles.
