happen to know that...food taken in must be digested , whatever not absorbed will be removed by egestion.saliva contains enzyme,begins the disgestion of starch and kill bacteria.mucus,makes saliva sticky,mositen and lubricate the food making it easy to swallow.the food,from bolus to pharynx then soft plate will conver the enterance to nasal cavity.from larynx moves to epilottis and then directed to oesophagus.from then enter the stomach.then to small intestine.small intestine got 3 section,duodenum 25cm long,jejunum 2.5m long,ileum 3.5m long.then cut short everything,in went into the large intestine..here comes the good info about making SHIT..lol first part large intestine, caecum.glands lining the walls of large intestine and produce mucus.this lubricates the passage of FAECES and protects the walls from being digested by any enzyme that remain.after it passes thru that,the colon,water absorbed from it.result in the chyme become solid or semi solid when it is known as FAECES.now the farting part,the characteristic of smell and gas occasionally released from "you know where" are also the work of bacteria feeding on the leftover carbohydrates.bilirubin excreted by bile and broken down by bacteria,gives faeces its brown colour.then move along to the rectum and then release la.
