Study Notes
Endocrine Glands
- Groups of secretory cells surrounded by an extensive network of capillaries, facilitating diffusion of hormones into the bloodstream
- Commonly referred to as ductless glands because hormones diffuse directly into the bloodstream
Hormones
- Chemical messengers or regulatory molecules secreted into the blood by endocrine glands
- Regulate total body metabolism, growth, and reproduction
- Carried in the bloodstream to target tissues and organs
Homeostasis
- The body's chemical messenger systems interact with one another to maintain homeostasis
- Homeostasis of the internal environment maintained partly by the ANS and endocrine system
Autonomic Nervous System (ANS) and Endocrine System
- ANS concerned with rapid changes, while endocrine control involved in slower and more precise adjustments
- Some chemical messengers secreted due to response to neural stimuli, making a sharp distinction between the nervous and endocrine systems not always possible on the basis of the chemicals they release.
