osteoclasts and osteoblasts

Explanation:

Osteoporosis is a metabolic condition that is characterized by progressive decrease in bone density and increased risk of fractures.

To understand what happens for this disease to occur, it must be remembered that bones are composed of a matrix in which mineral complexes are deposited with calcium. Another important feature is that they are in a constant process of renewal, as they are formed by cells called osteoclasts in charge of resorbing the aged areas and by others, osteoblasts, whose function is to produce new bones.

Another important feature is that they are in a constant process of renewal, as they are formed by cells called osteoclasts in charge of resorbing the aged areas and by others, osteoblasts, whose function is to produce new bones. This permanent and constant process enables bone to be reconstructed when fractures occur and explains why every ten years or so the human skeleton is completely renewed.

In other words, for osteoporosis to occur it is necessary that cells called osteoclasts begin to resorb bone faster and cells called osteoblasts cannot fill the holes that are being formed.

thinking it would be d not too sure but i think it's right
