ody Fluid Compartments 1. Extracellular - body fluid outside the body's cell 2. Intracellular - body fluid inside the body's cell 3. Intravascular - body's fluid outside the body's cell and within the circulatory system. 2. Define Osmosis Movement of Fluid across semi-permeable membrane from lesser solute to greater solute concentration. Dilutes concentrations back to homeostasis 3. Define Diffusion Exchange of gases across a membrane 4. Describe Fluid Shift when administered IV: Isotonic, Hypertonic, Hypotonic 1. Isotonic - no fluid shift due to same concentration of blood stream. 2. Hypertonic - fluid drawn into intravascular space from cells. 3. Hypotonic - fluid enters cell due to decreased osmotic pressure and decreased concentration. 5. 2 Requirements of cellular function Oxygen and Glucose 6. What electrolyte predominates intra-cellular Potassium 7. What electrolyte predominates extra-cellular Sodium 8. Electrolyte that moves out during depolarization Potassium, while sodium moves in via the "sodium potassium pump" 9. Anaerobic Metabolism and its end product cellular metabolism that occurs WITHOUT oxygen, producing lactic acid 10. 1 / 15 MICN Pretest Study Guide Study online at https://quizlet.com/_1ek477 Aerobic Metabolism and its end product cellular metabolism that occurs WITH oxygen, producing carbonic acid 11. 4 electrolytes for normal body functioning 1. sodium - attracts water for hydration 2. potassium - transmission of electrical impulse, too much or too little causes dysrhythmias. 3. calcium - cardiac and skeletal muscle contractions, and nervous impulse transmission 4. bicarbonate - buffers excess acids and is released by kidneys 12. Results of abnormal levels of potassium electrical instability and DYSRHYTHMIAS 13. Define Stroke Volume amount of blood pumped by the heart in one contraction (Normal is 80ml) 14. Define Cardiac Output 1. amount of blood pumped by heart in one minute (normal 5-6 Liter). 2. Stroke Volume x Heart Rate = Cardiac Output 15. Define Ventricular Diastole RELAXATION of ventricles 16. Define perfusion adequate blood supple to tissue and organ
