Endocrine 1 Flashcards
The endocrine system consists of endocrine ______ that secrete _______ into the blood. They are then transported to _____ ____.
- GLANDS
- HORMONES
- TARGET CELLS
What changes do hormones generally have on target cells?
METABOLIC ACTIVITY CHANGES
Comparatively speaking, what are the differences between the action of HORMONES and the action of NERVE IMPULSES?
- HORMONES = SLOW W/ PROLONGED EFFECTS
2. NERVE IMPULSES = FAST W/ SHORT DURATION
What is endocrinology the study of?
ENDOCRINE GLANDS
HORMONES THE GLANDS SECRETE
