(…) Kidneys are responsible for the balance of many key substances, including glucose, urea, sodium, amino acids, chloride and potassium to name just few. According to …… there are specialized proteins called transporters located on the membranes of the various cells of the nephron. These proteins aid in active transport of some of the larger ions, others are reabsorbed through passive diffusion. Many of these ions including glucose, potassium and chloride are main components of other functions in the other systems in the body. The kidney being able to reabsorb these key molecules is crucial. Sodium reabsorption is especially important because it is needed for a sodium potassium balance used throughout body. Muscle contractions including cardiac muscle and nerve impulses all depend on a sodium potassium balance that is maintained by the kidneys.
Water gets reabsorbed passively by osmosis in response to the buildup of reabsorbed sodium in spaces between the cells that form the walls of the nephron. Water balance in the kidney directly effects the blood water balance in the body. Soso discusses how our body’s cells are filled with a tissue fluid that is ideally kept at an isotonic state.(..) When at an isotonic state the concentration of cell fluid is the same as the cell contents. When the water balance in the cell is too high or too low cells can shrink or become bloated and lyse. According to the thirst is stimulated by an increase in plasma osmolality, a decrease in plasma volume, or a decrease in blood pressure. The water balance in the body also directly effects blood pressure.(…) Water balance is a very important part of the kidney’s many functions because the water balance effects, blood pressure, hydration status, and cardiac functions along with other systems.
The kidney is an extremely complex organ with many functions. Filtering out toxins is an important role that the kidney fills. It also reabsorbs key molecule that are used in other system of the body. Maintaining the body’s water balance is vital to the all of the systems in the body.
