the spongy bone
This bone was near blood vessels or organs.
In sheets over compact bone
On the outer surface of the compact bone is a layer of connective tissue.
Osteons (also called Haversian systems) form the basic structural unit of bone. Inside osteons we find the haversion canal - a central canal that contains the bone's nerve and blood supplies. The haversion canals surround these blood vessels and nerve cells. Communication with osteocytes in lacunae ("small lakes") through canaculi ("small canals") is possibly due to intercommunication channels between the haversion canals.
Well, honey, in the pulp cavity of a tooth, you'll find good ol' nerves and blood vessels. Those little guys are just hanging out in there, doing their job to keep your tooth alive and kicking. So, next time you're flossing, just remember to thank those nerves and blood vessels for keeping your pearly whites in check.
In the walls of organs or viscera, you would typically find layers of tissue that provide structural support, regulate blood flow, and facilitate the organ's function. These layers may include smooth muscle, connective tissue, nerves, and blood vessels.
blood & bone marrow
Blood vessels and nerves are primarily found in the dermis layer of the skin. The dermis lies beneath the outer epidermis and contains connective tissue, providing support and nourishment to the skin. It is where the majority of the skin's sensory receptors and vascular structures are located.
You will find plasma, white cells and platelets with red blood cells.
