Hormones act on target tissues to regulate the body activities is a <u>true </u>statement.
Explanation:
The main function of the hormones is regulatory in nature and regulates various body activities like the metabolic functions, cellular chemical reactions and transportation of materials.
Each hormone that is secreted from an endocrine gland is specific to a target tissue or an organ as a whole.
A target tissue or organ is the one which is intended to be affected by the hormone action. Receptor sites present in target tissues will act only in response to the specific hormone specified or intended to act upon the target tissue.
The hormonal messages are transferred only to those appropriate receptor sites of the target tissues through chemical bonding and not to other tissues.
For example, the adrenaline gland secretes the hormone adrenaline which acts upon the heart which is its target organ and increases heart rate and helps to prepare the body as a whole for any ‘fight or flight’ situation.
