BIO102 Unit 8 Fluid and Electrolyte Balance Assignment 2 ALL ANSWERS 100% CORRECT GUARANTEE GRDE A+

1. Identify the body’s main fluid compartments and explain the importance of water in the body. The importance of water in the body is for the use of Solvent, Transport, Thermoregulation, and Lubricants. Intracellular compartment and extracellular compartment. 2. Identify the six ions most important to the function of the body. Sodium Potassium Chloride Bicarbonate Calcium Phosphate 3. Define buffer and discuss the role of buffers in the body. Buffers maintain blood pH within the normal limits of (7.35-7.45). 4. Explain why bicarbonate must be conserved rather than reabsorbed in the kidney. The kidneys do not excrete bicarbonate, they ADD new bicarbonate to blood, thus reducing plasma H+ concentration (= increasing plasma pH) 5. Identify the normal range of blood pH and name the conditions where one has a blood pH that is either too high or too low. Blood pH within the normal limits of (7.35-7.45). 80 mmoles of bicarbonate is lost from the body. The person is in alkalosis (in this case, their urine pH = 8.0 alkaline) 6. Provide specific examples to demonstrate how the urinary system responds to maintain homeostasis in the body. Collects waste produced by cells and removes waste from the body. It helps maintain homeostasis By regulating the body PH, blood pressure and eliminating waste like urea and salt. 7. Explain how the urinary system relates to other body systems in maintaining homeostasis. Skin, liver and lungs to remove wastes.
