Here is a tip:

Endocrine glands are also called ductless glands.


Hormones are chemical messengers released into the circulatory system by endocrine glands. Although they share similarities with the nervous system, their functions and organization are well-defined, making them distinct from the nervous system.

Verified Answer

The endocrine system of an organism is a network of glands that specifically release chemical messengers called hormones into the circulation. Such messengers are transported in the blood to their unique receptors located on distant target organs that activate intracellular transduction pathways and cause various physiological effects.
