Endocrine System Flashcards

Front

Endocrine System

Back

Responds to the nervous system, by secreting hormones into the blood stream, to activate target cells

Front

Hormone

Back

Chemical messenger of the Endocrine System, used in Regulation

Front

Endocrine Glands

Back

Organs which secrete hormones into the bloodstream

Front

Target Cell

Back

A cell which contains the specific shape of receptor to allow the hormone into the cell to communicate (regulation)

Front

Circulatory/Cardiovascular System

Back

Where Endocrine Glands secrete the hormones for transport to the Target Cells.

Front

Regulation

Back

Life process, requiring the Nervous System and the Endocrine System to monitor and respond to stimuli in order to maintain homeostasis

Front

Negative Feedback

Back

The body responds in the opposite direction, in order to maintain homeostasis. Ex. Body temperature gets to high and the hormones make you sweat to cool down.

Front

Homeostasis

Back

Balance or regulation of the body systems.

Front

Dynamic Equilibrium

Back

Maintaining a range of balance, which increases and decreases to maintain homeostasis.
