: The ultimate goal of these hormonal interactions is to maintain a constant, balanced internal environment regardless of external changes.

The endocrine system is a network of glands that secrete chemical messengers called hormones directly into the bloodstream to regulate distant target organs.
: The system includes the Hypothalamus , Pituitary, Thyroid, Adrenal glands, Pancreas, and gonads (ovaries and testes). Core Functions : : Aldosterone and Antidiuretic hormone (ADH) regulate blood
: 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 ).
