there are over 15 canals in canada.
Volkman's canals
Sadly, the canals on Mars do not exist. although several astronomers reported seeing them, the canals are now believed to have been a combination of optical illusion and self-delusion.
Old canals such as those in Peru or Iraq were dug by hand with simple tools. They are narrow compared to modern canals and are not lined with waterproof material like concrete. Their main purpose was to irrigate fields for crops in marginal climate areas .Modern canals often bring in domestic and industrial water from hundreds of Km away ,whereas old canals were often short-2-20km.Modern canals in nations like New Zealand are mainly to redirect natural water courses to use the flow of water for HEP rather than for irrigation eg 80% of the natural water from the Wanganui River which exits to the SW was redirected northwards ,via drop shafts, canals, lakes and tunnels to Lake Taupo. The east and west diversion schemes from both watersheds of the central plateau of the North Island, increased the volume of water into L Taupo by 20%.The samewater runs through 10 HEP stations on its way north to the Tasman sea. Los Angeles ,a city of 7milion people, is in an area with only 250mm of rainfall annually.Large canals bring in water from snow melt from a branch of the Rocky Mountains far to the North east.
People though the supposed canals were signs of a civilization living on Mars.
Central canals extend longitudinally through bone tissue and transerse perforating canals connect them. -Brandy James :)
6. Blood vessels, lymphatic vessels, and nerves travel through compact bone via theA. canaliculi. B. lacunae. C. lamella. D. haversian canals.
The cement line is what connects the central canals. They are made up of different layers of compact bone tissue.
No, the canals are present in the compact bone (surrounds the spongy bone) and are called Haversian canals.
Bone cells surround Haversian canals. Osteon (Haversian system) is the structural unity of bone. Spaces for osteocytes are called lacunae. The matrix is present in concentric rings called lamellae. Canaliculi are canals that join lacunae with the central Haversian canal (central canal)

Haversian system is part of compact bone, which itself is a connective tissue.

If Audiology, continue.Associated with the inner ear, are the circulatory canals upon which we depend for balance.There are three of them, (yaw, pitch, roll) and each contains a tiny bone-like material, an otolith which rests on a bed of nerves, and which signals the state of balance. The otolith is composed of calcium and gel.The canals are fluid filled, and it is residual rotation, or recovery from pressure, that give us our dizziness.
The Haversian canals carry blood vessels and nerves to and from the bone.
Other passageways, known as perforating canals or Volkmann's canals, extend perpendicular to the surface. Blood vessels in these canals supple blood to osteons deeper in the bone and to tissues of the medullary cavity.
The circulatory system brings blood containing nutrients and oxygen to the periosteum, which covers the bone. The periosteum is a thin membrane that contains nerves and blood vessels. Its main function is to provide nourishment to the bone. From the periosteum, nutrients and oxybgen go through the perforating canals to the central canal, and then to the canaliculi. The osteocyte nearest the central canal passes nutrients to the next osteocyte with arm-like extensions that extend into the canaliculi to the next osteocyte. At the terminal end of each extension, gap junctions connect the cytoplasm of each osteocyte so that nutrients/wastes can be passed between cells to/from the central canal.
