This study explores the effects of hypoxia on osteoblasts and their role in bone maintenance and formation. It highlights how varying oxygen tension and pH levels influence osteoblast and osteoclast activity, leading to moderate and severe bone loss. With blood flow being a crucial factor, it examines the relationship between pO2 levels and bone cell function, providing insights into how maintaining normoxia can prevent bone deterioration. Understanding these dynamics can enhance strategies for preventing and managing bone density issues.
