Endocrine system

अंतःस्रावी तंत्र

In this Class 10 Science topic from the chapter Control and Coordination, students learn how the endocrine system regulates body functions through hormones. The topic introduces major glands such as the pituitary, thyroid, adrenal glands and pancreas, and explains how hormones influence growth, metabolism, stress responses and blood sugar control. Students also explore chemical coordination, the role of insulin and feedback mechanisms that help maintain balance within the body.
