FAQs on Chemical Coordination & Integration PPT Biology Class 11

1. What is chemical coordination in the human body?
Ans.Chemical coordination refers to the regulatory processes in the body that involve hormones and neurotransmitters, which help maintain homeostasis and control various physiological functions such as growth, metabolism, and reproduction.
2. How do hormones function in chemical coordination?
Ans.Hormones are chemical messengers secreted by endocrine glands into the bloodstream. They travel to target organs or tissues and bind to specific receptors, triggering changes in cell activity to coordinate and regulate bodily functions.
3. What are the major glands involved in chemical coordination?
Ans.The major glands involved in chemical coordination include the pituitary gland, thyroid gland, adrenal glands, pancreas, and gonads (ovaries and testes). Each gland secretes specific hormones that regulate different physiological processes.
4. What role does the nervous system play in chemical coordination?
Ans.The nervous system works alongside the endocrine system to achieve chemical coordination. It uses electrical impulses for rapid communication and neurotransmitters to send signals between neurons, allowing for quick responses to stimuli in conjunction with hormonal regulation.
5. How does chemical coordination affect growth and development?
Ans.Chemical coordination is crucial for growth and development as hormones like growth hormone, thyroid hormones, and sex hormones regulate processes such as cell growth, metabolism, and the development of secondary sexual characteristics, ensuring proper physical and reproductive maturation.
