Question

The elimination of the insoluble calcium phosphate takes place by

• A. Liver
• B. Kidney
• C. Lungs
• D. Large intestine

Answer 1

The correct option is D Large intestine

The calcium ions bind to the phosphates and are present in the dietary food. Sometimes, calcium phosphate are also consumed as an antacid. The calcium phosphate is a salt which is insoluble in water. The calcium ions are absorbed by the cells of the intestine as per the requirement. The excess of calcium and phosphate ions are excreted by the large intestine in the form of feces.

Thus, the correct answer is option D.
