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 hypothalamus is the processing centre in the brain that controls body temperature. It does this by triggering changes to effectors, such as sweat glands and muscles controlling body hair. Heat stroke can happen when the body becomes too hot; and hypothermia when the body becomes too cold.he hypothalamus is the processing centre in the brain that controls body temperature.
