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.
This center is located just above the brain stem and secretes hormones that help regulate body temperature. It is this part of your body that orchestrates the many functions that help to control body temperature. All of the autonomic responses of our bodies are controlled by the hypothalamus. It processes the sensory input that the body receives and passes it to the correct area of the brain and body for action. It is this part of your brain that allows you to feel both hot and cold.
