The Cell and General Physiology
Homeostatic Mechanisms Essentially all the organs and tissues of the body perform functions that help to maintain the constituents of the extracellular fluid relatively consistent, homeostasis. Extracellular transport system - Circulatory system Two stages - around the circulatory system and between the capillaries and the cells. Blood in the capillaries allows exchange between the cells and the interstitial fluid. Origin of Nutrients in the Extracellular Fluid. The respiratory system provides oxygen and removes carbon dioxide. The gastrointestinal system digests food and absorbs nutrients into the extracellular fluid. The Liver changes the components into usable form, and other tissue (fat cells, kidneys and endocrine glands) help modify the absorbed substances or store them till needed. The musculoskeletal system protection and support. Removal of metabolic End Products Kidneys regulate the extracellular fluid composition by controlling excretion...
