Which organ conserves nutrients, removes waste products, maintains blood pH, and controls blood pressure?

Explanation:
The kidney handles all of these functions. It reabsorbs essential nutrients and water from the filtrate, while waste products such as urea, creatinine, and uric acid are eliminated in urine. It keeps the blood pH balanced by managing bicarbonate and hydrogen ion levels. It also helps regulate blood pressure through the renin-angiotensin-aldosterone system, adjusting sodium and water balance and vascular resistance. Other organs like the liver, pancreas, and spleen have important roles in metabolism, digestion, and immunity, but they don’t perform this combination of filtration, reabsorption, acid-base balance, and blood pressure control.
