You are at an "all you can eat'' buffet. On the first pass through the line, you fill your plate with a
large quantity of foods. After eating it, you go back for a second portion of the foods you liked.
However, the food is less appealing the second time around, and you place a smaller quantity on
your plate because you feel full. Considering the physiology as you eat, (1) explain what
hormones are released (list specifically) as the stomach stretches. (2) List the area of the brain
that provides neural regulation and appetite suppression to inhibit eating. - answer✔As the

cholecystokinin (CCK). These hormones can travel to the brain (hypothalamus) and activate the
satiety center.

hormones decrease hunger, in specific leptin. They acitvate the satiety center in the brain which
creates a sense of fullness.
