Fluid Balance Explain in detail the fluid compartments of the body‚ including distribution of fluid and electrolytes within each compartment and the movement between compartments. In the average person water constitutes 60% to the total body weight.: 42L in a 70kg individual. 40% is intracellelular fluid‚ while remaining 20% is extracellular. The extracellular fluid can be divided into plasma (from intravascular compartment) and interstitial fluid intracellular fluid (28 L‚ about 35% of lean

Identify and describe the composition of the fluid compartments within the body Either Intracellular fluid (ICF- 2/3 of the body’s water) or extracellular fluid (ECF -one third of the body’s water). The two main extracellular fluid compartments are the interstitial fluid and the intravascular fluid‚ which is the blood plasma. Other ECF compartments include the lymph and the transcellular fluids such as the synovial ‚ intestinal‚

complete. Chemists also need to monitor how acidic or alkaline waste solutions from industries are before they are pumped into rivers or the sea. Regulations are strict as wastes or effluent that are too acidic or too basic can be harmful to the environment. • • Many people who are not chemists use indicators for: The water in aquariums needs to be tested. Fish are sensitive to changes in their water. If the water becomes too alkaline or too acidic it will kill fish and plants. The water in

Date: 03/20/2013 Lab: # Purpose of this lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function
