The human endocrine system is an essential coordination system that regulates various body functions using chemical substances known as hormones.
A clear anatomical map of the six major endocrine glands, their secreted hormones, and pathways into the bloodstream toward target organs.
The endocrine system is a coordination system that regulates body functions using chemical substances called hormones.
Endocrine glands are ductless glands that release hormones directly into the bloodstream. Hormones travel to target organs, triggering specific and long-lasting physiological responses such as the "fight or flight" reaction during emergencies.
Hormones are secreted directly into the blood circulation in small quantities. They act on specific target organs that possess suitable complementary receptors. A hormone can have more than one target organ. Hormonal responses are relatively slow compared to nerve impulses, but their effects are prolonged.
Each gland has a specific location, hormone and function.
Deficiency or excess of a hormone disrupts homeostasis and causes specific disorders.
