The expressed powers of the President are those expressed in the Constitution of the United States. Article Two of the United States Constitution creates the executive branch of the government, consisting of the president, the vice president, and other executive officers chosen by the president.
The small intestine is the 'work horse' of digestion, as this is where most nutrients are absorbed. Peristalsis is also at work in this organ, moving food through and mixing it up with the digestive secretions from the pancreas and liver, including bile.he food then enters the esophagus. The esophagus is a muscular tube extending from the pharynx and behind the trachea to the stomach. Food is pushed through the esophagus and into the stomach by means of a series of contractions called peristalsis.
These kinds of controls help you get the most nutrients out of your foods. Yet, the foods remnants must keep moving through the small intestine to avoid a traffic jam. Food is propelled through the small intestine by peristalsis, which is a wavelike series of muscular contractions. You might recall that peristalsis is also how food moves through the esophagus as it travels from the throat to the stomach. During peristalsis, the longitudinal muscles within the small intestine wall contract, and then the circular muscles contract, pushing the food down the tract.
