Endocrine system is as integrative systems of the Human body

Question

Why endocrine system is considered one of the integrative systems of the Human body?  And explain the other physiological systems that also have similar functions?

Answer 1

The endocrine system is said to have integrative nature because the hormones produced by the endocrine glands are substances that operate at a distance and many of them act in different organs of the Human body. So endocrine gland receives information from some regions of the body and they can produce effects in other regions providing functional integration for the body. The other physiological system besides the endocrine system also has integrative function that is the nervous system. This system integrates body all the way through a network of nerves connected to peripheral and central neurons. This endocrine system integrates the body by hormones that travel through the circulation and are produced by the endocrine glands.
