Body Systems Involved in Eating a Snack
The first thing I do when eating a snack is to prepare it. In this case, I reach into the cabinet above me and grab a bag of potato chips. I read the label and make sure they are plain chips, because I do not like flavored chips. When I am satisfied they are the type of chip I like, I break open the seal of the bag. I immediately smell the chips when I open the seal. The smell is familiar: oily, salty, and potato-ey. Still standing, I reach one hand into the bag of chips. My fingers feel all the salt granules and the distinct shape of the thinly sliced crisps. The edges of the crisps are rough but not sharp. I put one chip into my mouth and begin to chew. The initial flavors are salty, and then that gives way to sweet starchy tastes. After I finish the first chip, I automatically reach into the bag for another. After just two chips, my hands feel oily and...
Each time I finish chewing a chip, I place another one into my mouth without thinking about it. Suddenly I reach the end of the bag. There are no more whole chips. My fingers probe for broken chips and crumbs, which I move to my mouth. I lick my lips and throw away the bag before leaving the kitchen.
There are several body systems involved in this scenario. First, my musculoskeletal system is engaged as I reach for the bag of chips. The mechanisms involved in opening the bag, and in putting hand to mouth are also dependent on muscles and bones. However, my brain is also involved. I actively told my body to reach for the chips, but that was because I had a hunger signal in my brain. This shows that my autonomic nervous system was also engaged. My autonomic system takes over, as my musculoskeletal system knows exactly what to do in terms of contracting muscles, which help those muscles…

Therefore, in cases unrelated to ileocecal valve malfunction, large distal bowel obstruction is a direct function of LaPlace's Law at the area of the cecum. For the same mechanical reason, the most frequent location of colonic perforation is also at the cecum because it is the area of the largest diameter, and therefore, most susceptible to rupture in comparison to areas smaller in diameter. 11. What are the major types
Metabolic syndrome is significant for our patient for several reasons. As we have noted, the syndrome is associated with a higher risk of cardiovascular disease. Those patients who have metabolic syndrome tend to develop coronary atherosclerosis at a higher rate than those who have coronary risk factors alone. Obesity increases the risk of metabolic syndrome but so does pre-obesity, or BMI ranging from 25-30. Women who have been diagnosed with
Physiology & Food Related Social Issue Physiology and food-related social issue The chosen food-related social issue is the advertising of junk food as appealing to children. For years, the junk food industry has been accused for promoting obesity and ill-health among children Linn and Novosat 135. Junk food often contains unhealthy components because of the high content of calories, fats, and sugar Kime 317. The figure below shows that from the 1960s to the

Human Behavior, Physiology and Freedom What determines exactly where human behavior comes from? Who is the ultimate authority that in effect, evaluates the appropriateness of such behavior? What is freedom and to what extent does behavior influence freedom? What physiological and environmental factors contribute to the assessment of such factors? Is cultural design and the control of freedom and behavior the answer to solving behavioral issues? The answers to these questions are
Water: The Only Liquid the Body Needs To live a fully healthy and functional life, water is indispensible. From the point in history when primitive species moved from the oceans to land, a major factor of survival has continually been stopping dehydration. The important adaptations that enable this are present in almost all species of animals, including man. Water makes up varying percentages of the body weight of humans from 75%
