the opening of pre caval/superior venacave/ in right auricle is guarded by haversian valve. . .dont get confused by haversian system found in bone
Compact bone consists of a repeating structure called a Haversian system, or osteon, which is the primary anatomical and functional unit. Each osteon has concentric layers which are deposited around a central canal, also known as the Haversian canal, each containing a blood and nerve supply.
No it doesn't. Haversian systems are only found in compact/cortical bone.
The Excretory system
Components of Haversian system: osteocytes (spider-shaped bone cells that lie in "lacunae") that have laid down a matrix of collagen and calcium salts in concentric lamellae (layers) around a central Haversian canal containing blood vessels and nerves.The Haversian canal contains small blood vessels responsible for the blood supply to osteocytes (individual bone cells).

yes
haversian system is to consist to allow for the efficient delivery of oxygen and nutrients to the bone cells
Haversian system is part of compact bone, which itself is a connective tissue.
The Haversian System is the way bone is laid out. The Haversian Canal is in the center of each system. Blood vessels, arteries and nerves run through this hole (Haversian canal). The canal is surrounded by rings made of calcium much like the grains found in wood. These rings are called Lamellae. These are generally only 3 to 5 rings around due to the large decrease in diffusion that would take place otherwise. Located all about these rings are Osteocytes. These are cells that from the bone matrix (The non-living structure). They secrete calcium and other minerals. To protect these sells from being crush by there own byproduct, they are encased in a hard "shell" called a Lacunae. Finally, Canaliculi runs through the entire matrix. Canaliculi are the capillaries that connect the osteocytes to the Haversian canal. Those are the 5 basic components to the typical Haversian System.
Another name for the circulatory system would be the cardiovascular system.

Haversian Canals
The osteon is the structural unit of compact bone. Haversian system is a microscopic, structural unit of compact bone also called the osteon. The osteons are arranged in multiple layers or rings called concentric lamella.
I don't believe there is another name for the nervous system.
the another name of nervous system is (ns) surgery
