: Hormones like insulin and glucagon (from the pancreas) and thyroid hormones ( T3cap T sub 3 T4cap T sub 4 ) manage energy use and blood sugar levels.

: While the "classical" pathway involves hormones traveling through the blood, they can also act on nearby cells ( paracrine ) or even the secreting cell itself ( autocrine ). : The ultimate goal of these hormonal interactions

: Cortisol (adrenal glands) coordinates the "fight or flight" response.

: Aldosterone and Antidiuretic hormone (ADH) regulate blood pressure and hydration. Physiological Principles : Hormones like insulin and glucagon (from the

: Most endocrine functions are controlled by negative feedback , where the body's response to a hormone signal eventually turns off the original stimulus to maintain stability.
