why is it important for bones to have blood vessels

Bones having blood vessels is important because blood vessels supply oxygen, nutrients, hormones, and growth factors essential for the survival, development, regeneration, and remodeling of bone cells. The blood vessels also remove metabolic waste products from the bone. Additionally, blood vessels in bones regulate bone formation (osteogenesis) and are crucial for bone repair after injury or disease. They also provide specialized niches in the bone marrow for hematopoietic stem cells, supporting blood cell production. Impaired blood supply can lead to skeletal diseases and hinder bone healing and regeneration processes. Thus, the vascular system in bones is indispensable for maintaining healthy bone metabolism and supporting systemic functions related to the skeletal system.
