Uranium extraction from seawater: Uranium is most often mined from the Earth's crust, but it can also be extracted from seawater, which contains large quantities of uranium<span> (3.3 ppb, or 4.6 trillion kg). Theoretically, that amount would last for 5,700 years using conventional reactors to supply 15 TW of power.</span>
Answer:
Simplified answer: it's actually many systems that work together, just in different ways!
Explanation:
A large part of the body that is responsible for the regulation of temperature is the nervous system. The hypothalamus, which is a portion of the brain, controls the regulation of body temperature. The process that allows the human body to maintain its core temperature is called thermoregulation. The hypothalamus sends signals to various parts of the body, such as the glands and nervous system, when its core internal temperature begins to fluctuate too high or low.
However, the endocrine and the excretory systems also play a role in the regulation of body temperature.
Hope this helped!
