control and coordination class 10 NCERT pdf notes

Here's a brief introduction to control and coordination class 10 science:
"Control and coordination are fundamental processes in living organisms that ensure proper functioning and response to stimuli. In simpler terms, control refers to the regulation of various activities within an organism, while coordination involves the harmonious integration of these activities. In humans and many other animals, control and coordination are primarily carried out by the nervous system and the endocrine system. The nervous system allows for rapid responses to stimuli through nerve impulses, while the endocrine system regulates physiological processes using chemical messengers called hormones. Together, these systems ensure that organisms can adapt to changes in their environment, maintain internal balance (homeostasis), and carry out essential functions for survival and well-being."
