Answer:
The parts of the urinary system are kidney, ureter, bladder and urethra.
Explanation:
Urinary system is also known as the renal system. The urinary system is important to excrete out waste products from the body and maintains the balance of ions and pH in the body.
The parts of the urinary system are as follows:
Kidney: The kidney is present in pairs, one on each side. The functional unit of the kidney is nephron. The formation of urine occurs in the kidney.
Ureter: The urine formed in the kidney then pass to the urinary bladder through ureter. Ureter connects the kidney with the bladder.
Bladder: The main function of the bladder is the storage of urine.
Urethra: The urine stored in the bladder is expel out from the body by the urethra.
Answer:
The correct answer to the question: When the pH of the extracellular fluid drops, the kidneys:____, would be: C: excrete fewer bicarbonate ions.
Explanation:
The pH of the human body, given by the extracellular fluid that flows and is contained in it, holds a narrow margin between 7.35 and 7.45. When hydrogens ions increase, and bicarbonate ions decrease, in any of these fluids, be it blood, CSF, or any other, then we known that a person´s body is going into acidosis because the pH level is dropping. However, when the scenario is the opposite, with more bicarbonate ions, than hydrogen ions, then we are talking of an alkalosis. In order for the body to restore its normal levels, it has a series of mechanisms that will ensure the reestablishment of balance. One such mechanism is the excretion of elements through the urine, by the kidneys. In a case of acidosis then, the correct procedure is that kidneys produce urine charged with the excess hydrogen atoms and re-uptakes bicarbonate ions that might have escaped while producing urine. The urine will become acidic then. This is why the answer is C.
