DRAW the negative feedback involved with thermoregulation. Be sure to explain all parts of the feedback loop as well as why it is considered negative instead of positive.
Answer to the following question:
Body temperature -- when increases- the thermoregulation process stimulated by regulators skin and hypothalamus of brain--sends commands to blood vessels and sweat glands of skin--In this situation, the negative feedback mechanism increases blood flow to skin as well as increase sweating, such that homeostasis is maintained.
Body temperature -- when decreases- the thermoregulation process stimulated by regulators skin and hypothalamus of brain--sends commands to blood vessels and sweat glands of skin--In this situation, the negative feedback mechanism will stop sweating, and leads to vasoconstriction to reduce rate of heat loss.
The thermoregulation mechanism is known as negative feedback loop instead of positive, as the consequences of the effectors are the responses created that are opposite to the current situations that can lead to maintaining the homeostasis.
