Explanation:
Detailed explanation-1: -Calcium is actively absorbed from the small intestine in the presence of vitamin D. Calcium and phosphorus form hydroxyapatite crystals to mineralize and strengthen bones. Thus, a diet containing both optimal vitamin D and calcium is important for proper mineralization of bone.
Detailed explanation-2: -The body needs vitamin D to absorb calcium. Without enough vitamin D, one can’t form enough of the hormone calcitriol (known as the “active vitamin D”). This in turn leads to insufficient calcium absorption from the diet.
Detailed explanation-3: -(3) Vitamin D is absorbed in the jejunum and ileum by a mechanism capable of absorbing ∼75% of the vitamin D administered.
