satiety - the feeling of being full
hypothalamus - a region of the brain that plays a role in hunger as well the
feeling of being full
gastrointestinal tract (GI) - the main site in the body used for digestion and
absorption of nutrients
stomach - plays a major role in satiety and weight regulation (expands as it
starts to fill with food adding to the feeling of satiety)
hormones - compounds secreted into the bloodstream by one type of cell
that acts to control the function of another type of cell.
Hormones that increase hunger - ghrelin, endorphins, neuropeptide-Y
Hormones that decrease hunger (cause satiety) - leptin, serotonin,
cholecystokinin (CCK)
Leptin - alerts the brain to turn off the hunger center and activates the

the brain, it stimulates the hunger center as it deactivates the satiety
center
