Yes. Bones need a blood supply as much as any other tissue.
The Haversian canals carry blood vessels and nerves to and from the bone.

Yes, compact bone contains small blood vessels. These vessels are found within the Haversian canals, which are part of the osteon structure. The blood vessels supply nutrients and oxygen to the bone cells and help remove waste products, playing a crucial role in maintaining bone health. Additionally, small canals called canaliculi connect bone cells to these blood vessels, allowing for communication and nutrient exchange.
Perforating canals are channels in the compact bone that contain blood vessels and nerves. They connect the nutrient and longitudinal canals, allowing for the transportation of nutrients and waste products throughout the bone. Perforating canals are also known as Volkmann's canals.
The inner part of the bone is called bone marrow. In fact, new blood is produced in bone marrow, not the blood vessels.
Red blood cells are too small to contain blood vessels. They are cells and they travel in blood vessels.
Bone contains capillaries but cartilage does not.
Blood vessels that supply nourishment to the bone cells in compact bones are located in channels called Haversian canals. These canals run parallel to the long axis of the bone and contain blood vessels and nerves that provide nourishment and innervation to the bone cells within the osteon.
