P5- Explain dysfunction in relation to water balance and its possible treatments. M3- Discuss dysfunctions in relation to water balance and its possible treatments. For P5 and M3‚ I am going to explain the dysfunctions that relate to the balance between water intake and the disturbance of water output. Then I am going to discuss it in more detail. Oedema‚ also known as dropsy‚ is one of the dysfunctions and this is when there is too much fluid retention in the body. In other words‚ the accumulation

Material and Methods * Osmosis : -thistle funnel tube -dialysis tubing sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker
