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 of the brain works as the thermostat for temperature control inside the body. Throughout your body are temperature receptors that send feedback to the hypothalamus.If the hypothalamus receives indication that the body is either too hot or too cold, the brain will signal the body to react.For example, if you are outside on a hot day, temperature receptors on your skin will signal the heat to your hypothalamus which responds accordingly.hermoregulation. The body regulates its temperature by means of convection, conduction and evaporation. Convection is the change in temperature due to the movement of air or water over the skin, for example, a breeze while you are running.
