Endocrinology is a branch of medicine dealing with disorders of the endocrine system and its specific secretions called hormones.

Hormones are molecules that act as signals from one type of cells to another.

Most hormones reach their targets via the blood.

Although every organ system secretes and responds to hormones (including the brain, lungs, heart, intestine, skin, and the kidney), the clinical specialty of endocrinology focuses primarily on the endocrine organs, meaning the organs whose primary function is hormone secretion.

These organs include the pituitary, thyroid, adrenals, ovaries and testes, and pancreas..
