The canal spanned 350 miles between the Great Lakes and the Hudson River and was an immediate success. Between its completion and its closure in 1882, it returned over $121 million in revenues on an original cost of $7 million. Its success led to the great Canal Age.
An Integrated Temperature Regulatory Center. The whole brain helps regulate body temperature, but the main thermoregulatory center is the hypothalamus (located midline in the brain behind the eyes), which possesses two specialized sections: a heat-losing center and a heat-promoting center.
The skin is vital to good health because of its ability to regulate  body temperature. The hypothalamus signals the sweat glands to  begin producing perspiration when the bo â¦ dy temperature rises above  normal (approximately 98.6 degrees Fahrenheit). As the perspiration  evaporates from the surface of the body, cooling results. In  addition, during increased body temperature, the blood vessels near  the surface of the skin dilate to release heat to the exterior of  the body; conversely, if the body is too cool, these vessels  constrict to decrease heat loss.
