NURS 220 Lecture Notes - Lecture 19: Beta Globulins, Oncotic Pressure, Red Blood Cell
Document Summary
Transportation-fluid moving that transports nutrients (oxygen, c02) and hormones. Hemostasis-repair set of chemicals to repair little holes in blood vessels. Defense-white blood cells that defend against foreign materials. Body temperature-carries the heat that the body produces. Dilated blood vessels at peripheral allow heat to escape. Cells-surrounded by water, 45% of cells in blood. We use a comparison- water has a viscosity of 1. Extracellular fluid (water outside of cells)-33% of total body water. 80% of ecf is interstitial fluid-fluid around cells of solid organs. Plasma proteins: (serum is plasma without fibrinogen)-colloid (suspended): too large to be dissolved into the water so they become suspended. a) Transports things that can"t be dissolved in the blood. Globulins-transport molecules that transport things that are not soluble. (1) alpha and beta-lipoproteins: transport things that aren"t soluble gamma-proteins involved in defense mechanisms against bacteria (2) c) prothrombin and fibrinogen-for hemostasis.
