Yes. Bones need a blood supply as much as any other tissue.
A typical long bone such as the femur contains spongy bone and compact bone. Within compact bone are haversian canals, which contain blood vessels.
it helps the bloo vessels get through the bones
no
no
Yes, bones do have blood vessels. The blood vessels supply the materials that bones need to maintain or repair their structure. In compact bone, the vessels run though the Haversian Canals. Blood vessels also run through the softer inner bone, (cancellous or trabecular bone) which has a sponge-like framework.
The basic unit of a compact bone is an osteon. This is also known as the Haversian canal and it contains blood vessels that transport blood to the bone.
simple! blood
Except for the hardest sections of compact bone, bones are living tissue, and so must be provided with oxygen and the materials to maintain or repair themselves. The interior of most bones are an open framework of spongy tissue called trabecular or cancellous bone. In the outer bone, the Haversian Canals form conduits for nerves and blood vessels.
Bones contain nerves and blood vessels. The nerves and blood vessels go though channels in the bone, so that bone cells (osteocytes) have nutrition and commands from the nervous system. Broken bones hurt a lot, which is one way you know there are nerves in them!
No spngy bone does not contain osteons. Compact bone does contain osteons.
The human penis does not contain any bones, it is made up of spongy tissue that fills with blood during an erection.
