Flashcards
Endocrine glands
Endocrine glands
Glands that release hormones directly into the bloodstream, without using ducts.
Hormones
Hormones
Chemical messengers produced in trace amounts by endocrine glands, acting as intercellular signals.
Endocrine system coordination
Endocrine system coordination
The endocrine system coordinates and regulates physiological functions through slower but longer-lasting actions of hormones.

Study Notes
Endocrine Glands Characteristics
- One characteristic of endocrine glands is that they produce and secrete hormones directly into the bloodstream.
Definition of Hormones
- Hormones are defined as chemical messenger molecules that are produced by endocrine glands and transported through the bloodstream to reach their target cells, tissues, or organs.
Hormone Coordination
- Hormones provide endocrine coordination, which is a type of coordination that involves the transmission of signals through chemical messengers.
Endocrine-Neural System Coordination
- The endocrine and neural systems coordinate and regulate physiological functions through a complex interplay between the two systems.
- The endocrine system regulates slow, long-term changes in physiological functions, while the neural system regulates rapid, short-term changes.
Endocrine vs Neural System Coordination
- What distinguishes the endocrine system from the neural system in terms of coordination is the type of signals used (chemical messengers vs electrical impulses) and the speed of transmission (slow and long-term vs rapid and short-term).
