NCERT Solutions for Class 11 Biology Chapter 22 - Chemical Coordination and Integration

In the immediate above chapter, we have seen how the neural system maintains point-to-point rapid coordination between organs. This coordination provided by the neural system is fast, but not long. Therefore, a special form of coordination and integration is required, since the nerve fibres do not stimulate all cells of the body, and there is a necessity to regulate the functions of the cells continuously.

Hormones perform this special coordination function. The body's physiological functions are jointly regulated and coordinated by the neural system and the endocrine system. To know more about them read below.

• What is Endocrine Glands and Hormones
• The Endocrine System of Humans
