Document Summary
Physiology the study of the normal functioning of a living organism and its component parts, including all its chemical and physical processes. Anatomy the study of structure, with much less emphasis in function. Physiology encompasses many levels of organization, from the molecular level all the way up to populations of a species. Integumentary system composed of the skin; forms a protective boundary that separates the body"s internal environment from the external environment: musculoskeletal system provides support and body movement. Four systems exchange materials between the internal and external environments: respiratory system exchanges gases, digestive system takes up nutrients and water and eliminates waste, urinary system removes excess water and waste material, reproductive system produces eggs or sperm. Four systems extend throughout the body: circulatory system distributes materials by pumping blood through vessels, nervous/endocrine systems coordinate body functions. The function of a physiological system or event is the why of the system.
