GCSE Biology - Endocrine System & Hormones #59
Cognito・2 minutes read
The endocrine system consists of glands that release hormones into the bloodstream to regulate bodily functions, with key glands including the pituitary, thyroid, adrenal, pancreas, testes, and ovaries. Unlike the nervous system's fast, localized responses, the endocrine system's hormone-based communication is slower but has more widespread and longer-lasting effects on the body's cells.
Insights
- The endocrine system functions through glands that release hormones into the bloodstream to communicate with different body tissues, influencing cellular changes and bodily functions.
- While the nervous system uses electrical signals for quick, specific responses, the endocrine system's hormone-based communication is slower but widespread, impacting multiple cells throughout the body and having longer-lasting effects.
