Structural Organisation in Animals
Solution:
Haversian canals are narrow tubes within compact bone containing blood vessels and nerves. They generally run parallel to the bone surface. Each canal surrounded by a series of rings of bone (lamellae) is known as a Haversian system. Main function of Haversian system is transportation of nutrients and $O _{2}$ through blood. Haversian canals are connected by horizontal Volkmann's canals. They provide the major route for blood vessels from the marrow cavity to the Haversian canals of osteons.
