How there is a digestion?
Having passed a mouth and a throat, food gets to a long tube under the name a gullet. Let's notice that the sandwich eaten hastily or salad with ease will pass on it in any position of a body. It occurs thanks to automatic reduction of walls of a gullet – a vermicular movement. You can get up up legs – food all the same will get inside.
A what occurs further? Present that the chewed lump of food gets to the certain saucepan covered with a cover. Here only the saucepan is called a stomach, and the cover is special gastric muscles which open and close an entrance, periodically contracting. In a stomach food can be digested till 8 o'clock (usually 4 – 5), and it is helped with it by the gastric juice containing hydrochloric acid.
From a stomach the digested food gets into intestines where it is acquired through walls. All "a digestion garbage" gets into a rectum – they are not necessary to an organism!
Irregular food, abuse of spicy or dry food, having a snack on the run break digestion and quite often lead to gastritises, inflammation of intestines, and is frequent – and to stomach ulcer.
