MICROANATOMY

Detailed explanation-1: -As you age, your body may reabsorb calcium and phosphate from your bones instead of keeping these minerals in your bones. This makes your bones weaker. When this process reaches a certain stage, it is called osteoporosis. Many times, a person will fracture a bone before they even know they have bone loss.

Detailed explanation-2: -As we get older, our bone density slowly decreases. This is called bone loss or bone thinning. The hard, outer shell of the bones (compact bone) gets thinner and the holes in cancellous (spongy) bone get larger. In time, bones become more fragile. This is why bone fractures are more common after the age of 65.
