In this question, we’re asked to fill two blanks about body systems and calcium handling.
Option 1: 'digestive; respiratory' would pair calcium absorption with the digestive system and calcium elimination with the respiratory system. While the digestive tract is indeed involved in calcium absorption, the respiratory system is not the primary pathway for eliminating excess calcium from the body, so this pairing is not accurate.
Option 2: 'urinary; muscular' suggests calcium enters via the urinary system and exits via the muscular system. Calcium intake is not mediated by the urinary tract; rather, the urinary system handles excretion, and muscles respond to calcium, but this order is incorrect for absorption and elimination roles, making this option incorrect.
Option 3: 'respiratory; digestive' assigns entry to the respiratory system and exit to the digestive system. Calcium absorption predominantly occurs in the digestive tract, not the lungs, and removal is not primarily through digestion, so this is misleading and wrong.
Option 4: 'digestive; urinary' correctly assigns absorption to the digestive system (where calcium is absorbed from the diet) and elimination to the urinary system (where excess calcium is excreted in urine). This aligns with standard physiology: intestinal absorption of calcium and renal excretion of surplus calcium are the main routes for maintaining calcium balance.
Option 5: 'nervous; urinary' links absorption to the nervous system and elimination to the urinary system. The nervous system is not the site of calcium absorption, and while the urinary system does handle elimination, the first part of this pairing is incorrect, making the whole option invalid.
Taken together, the only option that faithfully matches the physiological pathways for calcium intake and clearance is the one stating 'digestive' for absorption and 'urinary' for elimination. The other choices either misattribute the primary sites of absorption or misidentify the elimination route, reflecting common misconceptions about where calcium moves in and out of the body.

While the Blank system is responsible for bringing calcium into the body, the Blank system is responsible for eliminating excess calcium.
