Water is one of the most important things that our bodies need to survive throughout our lives.In this essay I would like to talk about dehydration and Why is water important to the body. In addition to I would like to also talk about how dehydration happens. I want to talk about how to prevent from becoming dehydrated. First I would like to talk about the assents of water
Water is something that can be brought or you can get it from home to drink. Without water our bodies become dehydrated. When a person gets dehydrated our body functions start to lose energy, which causes our bodies ...view middle of the document...
Grosvenor and Smolin state, “The water is held in cells and other body compartments by the proteins, sodium, potassium, and other small molecules that are dissolved in your body water” (page 282, ch.9).
The process that moves the water in and out of the cells is called osmosis. Osmosis pushes water through cell membranes to equally distribute the sodium, potassium, and chloride molecules throughout our bodies. For instance, if the intracellular fluid on the outside of a cell detected a high concentration of potassium or sodium inside the cell, the fluid would pass through the cell membrane to regulate the level of the dissolved substances within the cell. The cell would then swell with the increased water content. All of these actions could not take place without blood pressure. Osmosis is also the path that water takes to travel in and out of the blood vessels. When blood pressure is higher, the pressure of the blood within the vessels pushes out water. As the blood pressure eases, osmosis lures the water back into the blood vessels (Grosvenor and Smolin, 2006).
Sodium, potassium, and chloride are electrolytes. These molecules are important for regulating fluid balance and acidity levels within our bodies. Electrolytes, as defined by Grosvenor and Smolin are, “Substances that separate in water to form positively and negatively charged ions that conduct an electrical current” (page 287, ch. 9). Sodium is a positively charged ion mostly found I outside the cells. Potassium, also a positively charged ion, is densely found inside the cells walls. Chloride is a negatively charged extracellular ion. When a movement is needed the body sends nerve impulses to the targeted cell. These nerve pulses are created by potassium and sodium ions, both positively charged, passing across a cell membrane (Grosvenor and Smolin, 2006).
Sodium and water are both necessary for our bodies. If our bodies lose too much of either one from sweating or exertion the result could be a loss of blood volume and blood pressure. The blood pressure change triggers the body to increase the amount of water and sodium detained by the kidneys. A tell tale sign of low sodium is muscle cramping. Today’s diet contains a lot of sodium as we are eating more processed foods. Additionally, we add salt to our foods during cooking and at...
