Question

Along with removing drugs from the body, the kidneys also __________. A. balance pH levels B. release hormones that regulate blood pressure C. release hormones into the stomach D. A and B

Answer 1

I think the answer must be B, although A is technically somewhat true too. Though the liver can regulate acid secretion, thus helping to balance the pH of blood by increasing or decreasing the acid secretion (can rid the body of excess acid through urine), the question doesn't specify that it balances the pH levels of BLOOD, and equally, multiple factors in the body have a role in balancing bodily pH levels, thus it is not the primary function of the liver. Thus, it must be B. The cells in the liver release an enzyme called renin, which activates angiotensin, which in turn activates the hormone aldostrene, which controls salt retention and elimination of potassium in the kidneys, thus affecting blood pressure and fluid balance.

Answer 2

The correct answer is option A and B.

Step-by-step explanation:

The kidneys play an essential role in sustaining a constant internal environment, that is, it does a vital role in maintaining homeostasis. The kidneys apart from removing toxic and drugs from the body helps in the regulation of pH by preventing blood plasma from turning too basic or too acidic by regulating ions.

The kidneys also produce hormones like erythropoietin that instigates the production of red blood cells and renin that assists in monitoring the balance of salt and water and blood pressure in the body.
