Biology 5B Animal Form and Function and Animal Energetics Kimberly Hammond 3318 Spieth Hall Khammond@ucr.edu •form and function •homeostasis •metabolism •thermoregulation •animal energetics Anatomy is the study of the biological form of an organism Physiology is the study of the biological functions an organism performs The comparative study of animals reveals that form and function are closely correlated Likewise, although many organisms are very different looking they often have organs that perform similar functions

Chemical reactions occur within cells There is the production of information (DNA) There is communication with the environment and, in multicellular organisms there is communication between cells 1.5 mm (b) Two layers of cells Exchange Exchange Mouth Gastrovascular cavity Exchange 0.15 mm (a) Single cell CONCEPT: Animal Form and Function Are Correlated At All Levels (Outline for Animal Form and Function and Animal Energetics) CONCEPT: Animal Form and Function Are Correlated At All Levels (Outline for Animal Form and Function and Animal Energetics) Chemical reactions occur within cells There is the production of information (DNA) There is communication with the environment and, in multicellular organisms there is communication between cells In animals with a tissue level of organization, different tissues have different jobs In higher organisms tissues are organized into organs that are further specialized All organisms regulate the cellular and organismal environment (Homeostasis) We will talk about the regulation of temperature and whole organism chemical processes (metabolism)
