In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva. Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food; the saliva also contains mucus, which lubricates the food, and hydrogen carbonate, which provides the ideal conditions of pH (alkaline) for amylase to work. After undergoing mastication and starch digestion, the food will be in the form of a small, round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric juice in the stomach starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. As these two chemicals may damage the stomach wall, mucus is secreted by the stomach, providing a slimy layer that acts as a shield against the damaging effects of the chemicals. At the same time protein digestion is occurring, mechanical mixing occurs by peristalsis, which is waves of muscular contractions that move along the stomach wall. This allows the mass of food to further mix with the digestive enzymes.

Beginning in first decade of the 15th century, Jan Hus—a Roman Catholic priest, Czech reformist and professor—influenced by John Wycliffe's writings, founded the Hussite movement. He strongly advocated his reformist Bohemian religious denomination. He was excommunicated and burned at the stake in Constance, Bishopric of Constance in 1415 by secular authorities for unrepentant and persistent heresy. After his execution, a revolt erupted. Hussites defeated five continuous crusades proclaimed against them by the Pope.
How did Jan Hus die?

Cork was originally a monastic settlement, reputedly founded by Saint Finbarr in the 6th century. Cork achieved an urban character at some point between 915 and 922 when Norseman (Viking) settlers founded a trading port. It has been proposed that, like Dublin, Cork was an important trading centre in the global Scandinavian trade network. The ecclesiastical settlement continued alongside the Viking longphort, with the two developing a type of symbiotic relationship; the Norsemen providing otherwise unobtainable trade goods for the monastery, and perhaps also military aid.
