SAT Language and Writing Practice Test Passage Title: Demystifying Digestion
1 What types of food are most easily digested? At first glance, the process by which food fuels our daily activities might seem inexplicable. However, upon closer examination, 2 digestion—the breakdown of food into smaller components to provide the body with necessary nutrients and energy— is a chemical and mechanical process with a consistent sequence of steps.
3 Chewing first involves putting food inside the mouth, where the grinding of teeth and secretion of saliva start to break down the physical and chemical composition of food.
Once the food has been transformed into 4 a compact mass referred to as a ‘bolus,’ it is swallowed and passes through the esophagus, a muscular tube connecting the throat to the stomach. Although the initial act of swallowing is voluntary, the lower third of the esophagus is made up completely of smooth muscle, over which an individual has no conscious control. This lower third attaches to the stomach—a hollow, muscular organ—which then 5 digest food both by crushing it mechanically and 6 secretes digestive enzymes and other fluids that break down starches and proteins. 7 The contents are then released into the small intestine.
Although all organs in the gastrointestinal tract are important for digestion, the majority of nutrient absorption occurs in the small intestine, which is a long, hollow tube arranged into a compressed mass around the center of the abdomen.
On the inner surface, this organ is lined with specialized 8 cells arranged into finger-like “villi” and circular “plicae” that facilitate the 8 transfer of important nutrients being transported into the bloodstream. The small intestine is 9 divided into three parts; he duodenum, the jejunum, and the ileum. In the duodenum, digestive juices from the pancreas and gall bladder enter through an opening referred to as the “ampulla of Vater.” These juices break down carbohydrates, lipids, and polypeptides into simpler molecules. The jejunum then links the duodenum to the ileum, which is where the majority of nutrient absorption takes place. 10 Instead, the remaining materials move into the large intestine, where water and salts continue to be absorbed.
Once in the bloodstream, nutrients from the digestive tract travel through the cardiovascular network to the liver and then to many different areas of the body. The 11 energy, from cellular division to muscle contraction, contained in these molecules can then be used to activate a number of biological processes. Although we are rarely aware of it, our bodies are constantly at work to provide us with the resources necessary to sustain our lives.
