Which 3 vitamins can impact the health of the connective tissue and skeletal systems of the body? How does each of these vitamins contribute to the health of these systems?

Answer 1

Vitamin A contributes to the health of the bones. This vitamin affects the expression of genes (DNA into protein), which can affect cell development. If vitamin A is deficient, the cells that build bone may not be fully functional. This could affect the quality of the bone tissue.
Vitamin D is essential for bone health. It stimulates the small intestine to absorb more calcium from foods so that the bones can make use of the calcium. Young people who lack vitamin D during growth may have softened, misshapen bones, as is seen with rickets. Older individuals may experience softening of the bones as calcium is released from them as a result of vitamin D deficiency. This condition is known as osteomalacia.
Vitamin C is needed for the formation of collagen, the base material of bones and other connective tissues. Vitamin C deficiency, known as scurvy, leads to poorly formed connective tissue, which can cause bleeding of the gums or rashes on the skin.
