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

Receptor

Back

A specifically shaped protein on the surface of the cell. Ex. Target cells have the correct shape for the hormone to communicate with the cell.

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

Feedback

Back

Information given to a system about its output

Front

Positive Feedback

Back

A system where the output amplifies the stimulus, causing it to keep going in the same direction rather than stabilizing or regulating. Ex. Cervix dilation in childbirth

Front

Negative Feedback

Back

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