This is referred to as hormonal stimulation and is readily illustrated by the activity of the pituitary gland, which controls the activity of all of the other endocrine glands. The thyroid hormones, e.g, regulate the body's metabolic rate but, in and of itself, the thyroid gland does not how much hormone to produce. This function is reserved for the pituitary gland which secretes thyroid stimulating hormone (TSH) which, in turn, stimulates the thyroid to produce its hormones. As thyroid hormone levels increase they, in turn, "stimulate" the pituitary gland to reduce its TSH stimulation. In actuality, a steady-state, mediated by their respective hormones, exists between the pituitary and the thyroid that maintains a constant level of thyroid hormones and, therefore, a relatively constant metabolic rate.
What else can I help you with?
What is the stimuli causing endocrine glands to secrete their hormones in direct response to changing blood levels of certain critical ions and nutrients are called?
Humoral stimuli cause endocrine glands to secrete their hormones in direct response to changing blood levels of certain critical ions and nutrients.
What are glands that secrete hormones into the blood called?

What are the three major types of stimuli for endocrine glands?
The three major types of stimuli for endocrine glands are: Humoral stimuli, which respond to changes in blood levels of ions or nutrients. Neural stimuli, which are initiated by the nervous system. Hormonal stimuli, which are triggered by other hormones from the hypothalamus or anterior pituitary gland.
Are Hormones produced by the ductless glands of the endocrine system?
No,endocrine glands are Ductless.Exocrine glands are the ductile glands.
What kind of Glands secretes hormones into the blood via tissue fluids?
Endocrine glands secrete hormones directly into the bloodstream via tissue fluids, allowing the hormones to travel throughout the body and exert their effects on target tissues. Examples of endocrine glands include the pituitary gland, thyroid gland, and adrenal glands.
What are the Ductless glands that secrete hormones known as?
Glands that secrete hormones do that into the blood, not into ducts. Hormones are not secreted into ducts. glands that secrete into ducts are called exocrine glands. Glands that secrete hormones are endocrine glands.
