Monday 4th February 2016. Acid base balance and Renal function The study of the renal system was completely new for me. I have already studying the renal structure but not in depth. And I Most of the aspect of this unit were new for me although I already knew the structure of the renal system I did not know about th The main role of the kidneys is to regulate body fluids within narrow limits by maintaining homeostasis (preservation of an internal environment), interacting with the endocrine system and excreting metabolic waste. To maintain homeostatic regulation electrolytes and balance of acid-base is an essential necessity which is controlled by the kidneys. The pH of arterial blood is regulated by the actions of two organs – which are…show more content…
Sodium is the major cation (positively charged ion) which is present in the ECF. The normal range for sodium is 135-145mEq/L. Sodium plays a role in fluid balance, osmotic pressure, muscle contraction and can be regulated by a sodium-potassium pump. When there are deficiencies in sodium (i.e. 145mEq/L) are known as hypernatremia. The kidneys try to counteract this by secreting ADH to retain water. Hyperaldosteronism (increased aldosterone levels which increase sodium reabsorption) can be another cause of hypernatremia. Other causes can include excessive fluid loss, high salt intake and increased kidney reabsorption. Symptoms of hypernatremia include dehydration, fever or coma. Overall regulating electrolytes are vital to maintaining a balance in keeping homeostatic conditions. Acid-base balance must also be sustained to enable maximum function of the kidneys. Both electrolytes and acid-base balance are important components regulated by the kidney and lungs to some extent; and keeping equilibrium and balanced levels will be beneficial for a healthy functionality of the kidneys.
