Final answer:
Vitamin A is important for bone development, Vitamin D aids calcium and phosphorus absorption for bone health, and Vitamin B2 is involved in metabolism through the electron transport chain.
Step-by-step explanation:
Vitamin A is crucial for normal growth and development because it plays an integral role in bone development; Vitamin D is essential for intestinal absorption of calcium and phosphorus and thus bone development; and Vitamin B2 (riboflavin) is an intermediate in the electron transport chain.
Calcium is a fundamental element of bone as it forms calcium phosphate and calcium carbonate. To maintain bone health, calcium must be taken from our diet. Yet, the body cannot absorb calcium without the presence of Vitamin D, making its intake paramount. Not only is Vitamin D critical for calcium absorption, but it also contributes to bone remodeling, a process that replaces old bone tissue with new tissue.
Vitamins are essential organic compounds aiding numerous body functions, including metabolism, and they are pivotal for cell, tissue, and bone growth. Among vitamins, B vitamins are key for metabolic processes, which highlights their significant role in overall health.
