The NCERT Exemplar Solutions for Class 11 Biology Chapter 22 – Chemical Coordination and Integration is the last chapter categorized under Unit 5 – Human Physiology. Students should expect close to 18 marks from this chapter alone, according to the Biology question paper design. This means that about a quarter of the questions on the exam will come from all of the chapters taught in this unit.
Exams are one method of evaluating the material that students have learned. Students are evaluated in exams by asking several types of questions, which allows the examiner to learn how students comprehend various subjects.
Following are the types of questions that can be asked in order to assess various capabilities of students:
- Evaluation type
- Remembering: knowledge-based
- Understanding
- Application type
- Higher-order thinking skills – Analysing and Synthesis
The subtopics that are discussed in Chapter 22 – Chemical Coordination and Integration are listed below:
| Number | Subtopic |
| 22.1 | Endocrine Glands and Hormones |
| 22.2 | Human Endocrine System |
| 22.3 | Hormones of Heart, Kidney and Gastrointestinal Tract |
| 22.4 | Mechanism of Hormone Action |
Introduction of Chapter
Chemical Coordination and Integration is the final chapter of Unit 5 – Human Physiology in Class 11 and is part of the term II CBSE Syllabus for the academic year 2021-22. Neural cooperation is quick but fleeting. The nervous and endocrine systems work together to coordinate and regulate the body’s physiological processes. Hormones are non-nutrient molecules that operate as intercellular messengers and are produced in trace levels in the endocrine system, where they play a critical role.
The hypothalamus, pituitary gland, pineal gland, thyroid gland, parathyroid gland, thymus, adrenal gland, pancreas, testis, ovary, and mechanism of hormone action are some of the topics covered.

Frequently Asked Questions on NCERT Exemplar Solutions for Class 11 Biology Chapter 22
Q. What is the difference between the exocrine and endocrine glands in Chapter 22 of NCERT Exemplar Solutions for Class 11 Biology?
Ans: 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.
