What are hormones?
A
chemical messages released by glands in the endocrine system
B
impulses that travel to neurons and deliver messages
C
muscles in the intestines that cause peristalsis
D
tissues in the endocrine system that send chemical messages
Explanation: 

Detailed explanation-1: -Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. Hormones can be thought of as chemical messages. From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell.

Detailed explanation-2: -The endocrine system is made up of glands that make hormones. Hormones are the body’s chemical messengers. They carry information and instructions from one set of cells to another.

Detailed explanation-3: -The cells in these glands secrete specific chemicals called hormones. Hormones circulate around the body via the blood stream and modulate cellular or organ functions by binding with receptors in the target cells. Hormones that stimulate and control the activity of other endocrine glands are called trophic hormones.

Detailed explanation-4: -One of the most significant differences between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.
