Haversian canals [i] (sometimes canals of Havers, osteonic canals or central canals) are a series of microscopic tubes in the outermost region of bone called cortical bone. They allow blood vessels and nerves to travel through them to supply the osteocytes .
Each osteon consists of concentric layers, or lamellae, of compact bone tissue that surround a central canal, the Haversian canal. The Haversian canal contains the bone's blood supplies. The boundary of an osteon is the cement line. Each Haversian canal is surrounded by varying number (5-20) of concentrically arranged lamellae of bone matrix.

Volkmann's canals, also known as perforating holes or channels, are anatomic arrangements in cortical bones that allow blood vessels to enter the bones from periosteum. They interconnect the Haversian canals (running inside osteons ) with each other and the periosteum.
The Central Valley is a region known for its agricultural productivity. It provides a large share of the food produced in California. California provides more than half of the fruits, vegetables, and nuts grown in the United States. [3] More than 7,000,000 acres (28,000 km 2) of the valley are irrigated via reservoirs and canals.

The Delta–Mendota Canal is a 117-mile-long (188 km) aqueduct in central California, United States. The canal was designed and completed in 1951 by the U.S. Bureau of Reclamation as part of the Central Valley Project. It carries freshwater to replace San Joaquin River water which is diverted into the Madera Canal and Friant-Kern Canal at ...
The UC team said California could meet about 15% its electricity demand with solar panels on all 4,000 or so miles of canal statewide. That’s a quarter of the way to the mandate for 60% climate ...
In Central California, the system will have stations in Merced, Madera, Fresno, and the Kings–Tulare area. Planning is underway to extend the initial line to San Francisco/San Jose and Los Angeles. Freight rail is served by commercial railroads. Union Pacific Railroad and BNSF Railway operate mainline freight through the region in the Central ...
