5E: The Endocrine System Flashcards
- What is a hormone and what kinds of tissues and organs are they produced by? -How do hormones travel around the body and communicate to target cells?
What is ADH
ADH (antidiuretic hormone) is found in the nephron and promotes the absorption of water (not watery/less water)
ADH does
manages water levels and promotes water absorption
Aquaporins
are protein channels specific for water
ADH triggers
the creation of more aquaporins to absorb more water
Less ADH results in
less aquaporins
Coffee suppresses the release of what, what does this mean
ADH - means that it does not hydrate you as there is no aquaporins (therefore water is not being absorbed) that are activated by the release of ADH which has been suppressed
Endocrine cellular process
)endocrine cell (releases hormone) –> target cell (hormone goes/binds to specific receptor–>activates cascade response (a series of events that flow on from each other))
OR
)endocrine cell (releases hormone) –>non-target cell (no receptor for hormone)
The endocrine system is made up of
glands that make hormones.
Hormones are
Hormones are chemical substances that act like messenger molecules in the body.
