The inhibition of TSH secretion by an increased blood concentration of thyroid hormones is an example of negative feedback. Negative feedback is a mechanism where the output of a system inhibits or reduces the input, thus stabilizing the system. In this case, the high levels of thyroid hormones act as the output that inhibits the secretion of TSH from the pituitary gland, which acts as the input. This helps to maintain a balance and prevent overproduction of thyroid hormones.
