Have narrower effects than the nervous system.
D
Travel along nerves.
Explanation: 

Detailed explanation-1: -The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived. Signal transmission in the endocrine system is slow, since hormones must travel through the bloodstream, but the responses tend to last longer.

Detailed explanation-2: -Hormonal responses are slower than the reflex actions because hormones, which initiate and control the responses, are chemicals transported by blood. On the other hand, in reflex actions, the impulses are electrical in nature and are transmitted by specialised cells called neurons that make up nervous tissue.

Detailed explanation-3: -Hormones can control the body, and the effects are much slower than the nervous system, but they last for longer. There are important differences between nervous and hormonal control.

Detailed explanation-4: -Hormones are your body’s chemical messengers. They travel in your bloodstream to tissues or organs. They work slowly, over time, and affect many different processes, including: Growth and development.
