Key Topics Covered in Chapter 22 Chemical Coordination And Integration NCERT
1. Endocrine Glands and Hormones
The endocrine system consists of glands that release hormones directly into the bloodstream. This section provides an in-depth look at major glands like the pituitary, thyroid, adrenal glands, and more. Each gland plays a unique role in regulating body functions such as growth, metabolism, and reproduction.
2. Human Endocrine System
This topic focuses on the detailed study of each gland within the endocrine system. The pituitary gland, often called the “master gland,” controls several other hormone-producing glands. Other glands, such as the thyroid and adrenal, have specific roles essential to physiological balance.
3. Mechanism of Hormone Action
Hormones work by binding to receptors, which triggers specific cellular responses. This section examines how hormones like insulin, adrenaline, and growth hormones initiate changes in target cells. By understanding these mechanisms, students gain insights into how hormonal imbalances can lead to conditions such as diabetes or hyperthyroidism.
4. Hormonal Functions and Deficiencies
Different glands produce hormones that control specific body functions. For instance, the pancreas releases insulin to regulate blood sugar levels, while the adrenal glands produce cortisol in response to stress. This section also covers what happens when there is a deficiency or excess of these hormones, which is crucial for practical knowledge in both medical and biological fields.

FAQs on Chemical Coordination And Integration NCERT
What is chemical coordination and integration in Class 11?
Chemical coordination and integration involve the regulation of physiological processes in the body through hormones, which are secreted by endocrine glands like the pituitary, thyroid, and adrenal glands. This chapter in Class 11 Biology highlights how hormones coordinate bodily functions to maintain homeostasis.
Is chemical coordination and integration important for NEET?
Yes, it is a vital topic for NEET as it covers concepts related to the endocrine system and hormonal functions, which frequently appear in NEET exam questions. A thorough understanding of this topic is crucial for tackling physiology-related NEET questions effectively .
What is the difference between the exocrine and endocrine glands in Chapter 22 of NCERT Solutions for Class 11 Biology?
Exocrine gland –The glands that secrete their secretions into ducts that carry them to specific organs or to the body's surface. Endocrine gland – The ductless glands release their secretions into the circulation, which then transports them to distant target organs.
