Final answer:
The sensation of fullness, or satiation, leads to the termination of a meal when physiological signals are sent to the brain to stop eating. Hormones like leptin are involved, and external factors can influence feelings of hunger or fullness. The correct answer is that satiation causes you to sense fullness and end your meal.
Step-by-step explanation:
Satiation affects eating because it involves the sensation of fullness and satisfaction that leads to the termination of a meal. This feeling of being satiated is regulated by several physiological mechanisms, such as the increase of blood glucose levels that trigger the pancreas and liver to send signals to stop hunger and eating. The gastrointestinal tract sends signals of satiety to the brain as well, and fat cells release leptin, a hormone associated with satiety. The correct answer to how satiation affects eating is: b. you sense fullness while eating and terminate the meal.
Feeling hungry can be influenced by various factors, including the empty stomach sending messages to the brain, nerves and hormones monitoring digestion and blood sugar levels, as well as external stimuli like the sight and smell of food. Additionally, the social and cultural environment, including advertising and family eating habits, play a significant role in what and when we choose to eat. Exercise is also a factor; it can both suppress and stimulate appetite, as it induces the body to produce hormones that can either decrease or increase hunger post-exercise.
