If blood transports hormones throughout the body,how do they communicate with specific targets?
A)Special gateway valves in the blood vessels direct hormones to their target tissues.
B)Special carrier proteins "walk" along microtubule tracts to deliver the hormones to their targets.
C)Axonal pathfinding mediates the delivery of hormones to their specific targets.
D)Only target tissues have receptors that allow them to receive the signal.

Hormones are only able to activate receptors on specific target tissues, which allows for specific communication with these tissues. Other tissues in the body may not have the appropriate receptors or may only have low levels of them, which prevents activation by the hormone. Therefore, the specificity of the target tissue's receptors allows for efficient and precise communication between the hormone and its intended recipient.
