Which system of the body is responsible for hormone production?
A. Circulatory system
B. Digestive system
C. Endocrine system
D. Nervous system
Answer (1)
Correct Answer: C. Endocrine systemThe endocrine system is a network of glands that produce and release hormones, which are chemical messengers that regulate various body functions such as growth, metabolism, mood, and reproduction. These hormones travel through the bloodstream to target organs and tissues, triggering specific responses.Major glandsPituitary gland – the “master gland” that regulates other endocrine glands and controls growthThyroid gland – controls metabolismAdrenal glands – produce stress hormones like adrenaline and cortisolPancreas – regulates blood sugar through insulin and glucagonOvaries and testes – produce sex hormones like estrogen, progesterone, and testosteroneUnlike the nervous system, which uses fast electrical signals, the endocrine system communicates more slowly but has longer-lasting effects. For example, puberty involves gradual changes due to hormones like testosterone and estrogen.Hormonal imbalance can lead to:Diabetes (insulin imbalance)Thyroid disorders (hyperthyroidism or hypothyroidism)Growth hormone deficiencyComparison with other systems:The circulatory system transports hormones but does not produce themThe digestive system processes foodThe nervous system uses neurotransmitters, not hormones
