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
  • Hormones present in Kidney, Gastrointestinal Tract, and Heart
  • Mechanics applied in Hormone Action

The last chapter for class 11 Biology' Chemical Coordination and Integration' explains the concept of endocrine glands present in the human body. The chapter has been explained minutely through diagrams so that students exactly trace the location of the endocrine glands inside the human body.

In this chapter, Hormones are defined as non-nutrient chemicals whose nature is like intercellular messengers and which generate in huge numbers to play a pivotal role in the endocrine system. Also discussed is an overview of FSH's process and the hormonal deficiencies occurring in different parts of the human body. Some other topics introduced in this chapter are the pituitary gland, thyroid gland, pineal gland, hypothalamus, thymus, parathyroid gland, pancreas, adrenal gland, ovary, testis, and the mechanism of hormonal action.
