Describe the physiological process of hunger. Include a discussion about glucose, the hypothalamus, set point, ghrelin/leptin, and basal metabolic rate in your response. Then, describe the cultural and situational factors that influence hunger.
Answer:
Ghrelin is made in the stomach. It stimulates hunger by entering the brain and acting on the neurons in the hypothalamus to increase the activity of the hunger-causing nerve cells and reducing the activity of hunger-inhibiting cells. As the stomach empties, the release of ghrelin increases. Leptin is a protein produced by fat cells that is a hormone acting mainly in the regulation of appetite and fat storage. When your blood sugar levels are too low, your cells become starved for energy. At first, you might notice minor symptoms, such as hunger and headaches. However, if you don’t get your blood sugar levels up in time, you may be at risk for serious complications. Introducing more glucose into your body will help solve the problem of low blood sugar. Our hunger is influenced not only by our physical state but also by our memory of when we last ate and our expectation of when we should eat again, this is what the hypothalamus does. According to set point theory, after a time, your body will fight reduced calorie intake by sending signals (hunger indications) and slowing down your metabolism to attempt to bring you back to your normal set point. Basal Metabolic Rate is the number of calories required to keep your body functioning at rest. BMR is also known as your body's metabolism; therefore, any increase to your metabolic weight, such as exercise, will increase your BMR. Everyone's basal metabolic rate is different. Although we humans as a species prefer certain tastes (such as sweet and salty), we learn to satisfy those preferences with specific foods eaten in the context of our families and our culture. Some of our taste preferences, such as the avoidance of new foods or of foods that have made us ill, have survival value.

Ghrelin is made in the stomach. It stimulates hunger by entering the brain and acting on the neurons in the hypothalamus to increase the activity of the hunger-causing nerve cells and reducing the activity of hunger-inhibiting cells.
Which cells are responsible for hunger?
Ghrelin is a multifaceted gut hormone which activates its receptor, growth hormone secretagogue receptor (GHS-R). Ghrelin's hallmark functions are its stimulatory effects on food intake, fat deposition and growth hormone release. Ghrelin is famously known as the “hunger hormone”.
Moreover, when food is scarce, some brain cells begin to devour themselves, activating an appetite-stimulating molecule in the process. A brain region called the hypothalamus contains neurons that regulate feeding in response to nutritional signals.
Therefore, within the hypothalamus are nerve cells that, when activated, produce the sensation of hunger. They do so by producing two proteins that cause hunger: neuropeptide Y (NPY) and agouti-related peptide (AGRP). Quite close to these nerve cells is another set of nerves that powerfully inhibit hunger.

Describe the levels of cellular organization in an animal, and explain how organs work together as a system.
Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.
