Ok, this will be necessarily brief, but Vitamin D acts more like a hormone in your body than a vitamin, and proper amounts of D affect calcium uptake. And lots of other processes.
Calcium and vitamin A help to aid in bone development. Eating a good diet also helps to continue healthy bone development.

Vitamin D and Calcium...i think
Your bones need calcium for developing and strengthening. (Same for teeth).Vitamin D is important in bone development.
Bones require large amounts of calcium and phosphorus. Also Vitamin D is important for bone development.
Since vitamin D is necessary for bone development and growth, some sort of problems will occur in the bones. In children is causes something called rickets and in adults it will cause thin and/or weak bones. These are called osteopenia (little bone) and osteoporosis (bone with holes).
Calcium is needed to repair bone tissue making them strong and dense.
The main functions of Vitamin A are the repair and maintenance of body tissue, infection resistance, Bone growth and helps develop nervous system. It is found in milk products, spinach, carrots etc. Lack of Vitamin A can lead to Night Blindness (not being to see in the dark) Bone growth cessation diarrhoea dry skin. So, really; Vitamin A is rather quite important!
Because Vitamin A is a fat-soluble vitamin so it is involved in the formation and maintenance of healthy skin, hair, and mucous membranes. Vitamin A helps us to see in dim light and is necessary for proper bone growth, tooth development, and reproduction.
