8. Water regulation Describe how the body regulates water. In your answer include: the name of the organ and hormone primarily responsible for the control. Then describe how the following will affect the level of the hormone and how that would affect water retention vs water excretion. Describe what will happen if we overhydrate. Hormone level: How will this effect water control? What would be the response if we become dehydrated? Hormone level: How will this effect water control? What would be the response to ingestion of alcohol (in terms of hydration and hormone level)? Hormone level: How will this effect water control?

ok I know hypothalamus is going to sense the high osmolarity of the blood, JGA sense low blood pressure with activate RAAs and release renin which going to convert into angiotensin and what? that’s where i got stuck…

The given data infers hypernatremia which indicates kidney problems or water imbalance in the body. Hypernatremia describes the conditions when the sodium in the blood is in excess amount. To cope with the sodium, the kidneys have to work for extra time; And this excess sodium could be removed only with water, so excess urination is observed. Now since water/fluid is lost by urination so to compensate for it the body sends signals of thirst and so the person feels increased thirst. This is why the patient complains of polyurea and polydipsia. Also, the low potassium levels and increased sodium levels indicate water imbalance If not treated, this may result in a higher risk of diseases such as stroke and hypertension.     Can you suggest treatment for this situation please?
