Explanation:
Detailed explanation-1: -Hormones are released into body fluids, usually blood, which carries them to their target cells where they elicit a response. The cells that secrete hormones are often located in specific organs, called endocrine glands, and the cells, tissues, and organs that secrete hormones make up the endocrine system.
Detailed explanation-2: -Hormones are chemical messengers that interact with receptors present on the surface of a cell membrane or with receptors that are located inside the cell, in the cytoplasm (cytoplasmic receptors). This interaction gives rise to the effects hormones exert on target cells and organs.
