How does the negative feedback system work to control hormone levels in the blood ?

please help !!!!!!How does the negative feedback system work to control hormone levels in the blood ?
When some hormones are secreted in your body, they are done so by signalling hormones.


For example





Your pituitary gland in your brain secretes TSH (thyroid stimulating hormone). As the name lets you infer, this hormone when it reaches your thyroid gland will STIMULATE your thyroid to produce thyroid hormones (thyroxine and tri-iodothyronine).





To avoid overproduction/secretion of these thyroid hormones, these hormones will NEGATIVELY feedback on to the pituitary gland to stop production of TSH. This will then stop production of thyroid hormones to keep things in balance.
