Chemical Messengers
- Hormones are chemical messengers produced by cells to regulate the activity of other cells.
- Hormones are delivered through various routes, including the bloodstream, affecting distant target cells.
Body Systems
- The nervous system controls more rapid activities, responding quickly to stimuli.
- The endocrine system regulates slower functions, such as growth, metabolism, and mood.
Hormonal Function
- In the endocrine system, hormones are released into the circulation and transported via blood vessels to target cells.
Central Nervous System
- The involvement of the central nervous system (CNS) is crucial for coordinating actions and responses throughout the body.
