High levels of TSH initially increases the level of thyroid hormone (TH). When the TH levels get high, the feedback mechanism starts to work: The excess amount of TH in the blood signals the pituitary gland to decrease secretion of TSH, which decreases the amount of TSH that is secreted by the pituitary gland, and maintains homeostatis.
Thyroid function is an example of a negative feedback system.

High levels of TSH initially increases the level of thyroid hormone (TH). When the TH levels get high, the feedback mechanism starts to work: The excess amount of TH in the blood signals the pituitary gland to decrease secretion of TSH, which decreases the amount of TSH that is secreted by the pituitary gland, and maintains homeostatis.
The most common controlling mechanism of hormone secretion is a feedback system or circuit. An example of this is body temperature, a condition that is continuously monitored and adjusted as necessary so that the body can function properly.
Homeostasis
lungs as a homeostasis organ
Primary homeostasis includes vascular constriction and platelet plug( aggregate plug) formation in response to bleeding. Mainly vessel function and platelet function are mainly concerned in primary homeostasis.
Not directly. Homeostasis usually involves the proper function of a system or systems.
It works on thyroid.It stimulates production of thyroxine.
Homeostasis is not a function carried out solely by the respiratory and cardiovascular systems. It Homeostasis is actually carried out in all cells and all systems.
to regulate a process
Vasoconstriction and Vasodilation are a part of a body negative feedback, in which the body tries to restore homeostasis. Homeostatis is the function of keeping the internal body at it's general temperature (37 degrees Celsius). Without the negative feedback of Vasoconstriction and Vasodilation, the body would either be at a very low or very high temperature and this high/low temperature could cause death.
