CASE STUDY: HOMEOSTASIS Sоdium plаys аn impоrtаnt rоle in your body. It is an electrolyte, meaning that it can cause electrical signals within your cells. Electrolytes are essential to critical body functions such as muscle movement and nerve impulses. Sodium also helps to maintain normal blood pressure and regulates your body's fluid levels. Although sodium is found within your cells, it is primarily located in the body fluid around your cells. Kim recently signed up to run her first half-marathon. In preparation for the race, she drank 2 gallons of water in the morning before arriving at the starting line. During the race, she drank at the provided water stations. Although she was beginning to feel nauseous, she was able to finish the race. She complained to her friends about feeling dizzy and then vomited. Thinking she was dehydrated, her friends encouraged her to drink more water. She went home to rest. Her roommate found her dead in their apartment the next day. Osmosis is the movement of water through a membrane from high concentration to lower concentration. When solutions are originally balanced on both sides of a membrane, scientists say that the cell is in an isotonic solution. When a cell is in a solution that has a higher concentration of solute (like sodium) than the cell does (called a hypertonic solution), the water inside the cell will rush out to equalize the concentration. Dehydration occurs if cells are left in this state. When a cell is in a solution that has a lower concentration of solute than the cell does (called a hypotonic solution), the water will rush into the cell to equalize the concentration. In animal cells, this can cause the cell to swell and sometimes burst from the influx of too much water. Hypertonic Isotonic Hypotonic Question: Which type of solution was Kim causing by drinking so much water?
