1. Discuss in 150 words one of the following prompts:
In this chapter you have learned- solutions, water and electrolytes in body fluids, equivalents of electrolytes in clinical intravenous (IV) solutions, solubility rules, problem of saturation in body fluids, solution concentration and dilution.
2. Read and respond in a paragraph of 100 words to each of the following posts. Lets us know if you agree or disagree, given at least three reasons to support your point.
First peer response (reply in a paragraph of 100 words):
Solutions and Electrolytes in Body Fluid
Today I am going to discuss solutions and electrolytes! Solutions are homogenous mixtures of two or more substances. They are made of two parts: the solvent and the solute. There is much more solvent than there is solute. For example, in salt water, the water is present in a large amount and is the solvent while the salt is present is much smaller amounts and is the solute. In simple words, the solute is dissolved into the solvent.
Electrolytes play a critical part in the function of cells and organs. Strong electrolytes, weak electrolytes, and nonelectrolytes are all found in the body. A strong electrolyte, such as NaCl, fully dissociates in water and produces positive and negative ions. A weak electrolyte, such as HF, only slightly dissociates in water. Only a few ions are produced by weak electrolytes. Nonelectrolytes, such as CH4O, do not dissociate in water at all, therefore, do not produce any ions.
Second peer response (reply in a paragraph of 100 words):
Water and Electrolytes in Body Fluids
Today I will be talking about water and electrolytes in our body and why they play such an important role in our bodies. Electrolytes balance the amount of water in our bodies, move nutrients through our cells and balance our pH levels. Growing up as an athlete, it was always so important to get your electrolytes in your body, because of all the sweat and activity I was doing. When your electrolytes begin to get low, you can start to have symptoms like blood clotting, muscle contractions/spasms, impaired body functions, etc. Along with electrolytes, water is another key importance to our body. Water keeps your body at a healthy temperature, helps get rid of waste, etc. Believe it or not, water actually goes hand in hand with electrolytes… The electrolytes in our body are what move water throughout the body. Our body is like a well-oiled machine, everything has a role/job for an important meaning.
