Question

question: the organ responsible for filtering up to 95 percent of the water from blood and maintaining body ph is the answer options: select one of four urethra. kidney. gallbladder. pancreas.

Explanation:

To solve this, we analyze the functions of each organ:

• Urethra: Transports urine out of the body, not for filtering blood or pH maintenance.
• Kidney: Filters blood, reabsorbs ~95% of water, and regulates pH by balancing ions and acids/bases.
• Gallbladder: Stores bile, no role in blood filtration or pH.
• Pancreas: Produces enzymes/hormones, not for blood filtration or pH regulation.

Answer:

B. kidney.
