BIOD27H3 Chapter Notes - Chapter 1: Extracellular Fluid, Integumentary System, Human Musculoskeletal System
Document Summary
Physiology; study of the normal functioning of a living organism and its component parts including all its chemical and physical processes. Both physiology and anatomy go hand in hand. Atoms-molecules- cells-tissues-organs-organ systems-organisms-population of one species-ecosystems of different species-biosphere. Cell; smallest unit of structure capable of carrying out all life processes: molecules are separated from external environment by barrier called cell membrane. Tissues; collections of cells that carry out related functions: tissues form structural and functional units know as organs. Group of organs combine their functions to make an organ system. Integumentary system; composed of skin forms protective boundary which separates body"s internal environment from external environment (outside world) Musculoskeletal system; provides support and body movement. Digestive system; takes up nutrients and water and eliminates waste. Urinary system; removes excess water and waste material. Circulatory system; distributes materials by pumping blood through vessels.
