Digestive System Facts: The liver is the larg est internal organ, which perfo rms over 500 functions Your stomach incr eases up to twenty times its or iginal size after eating RNEY U 4 1 Our salivary glands produce around 1.5 litres of saliva each 4 day Small intestine Your small intestine isn’t that small at all – in fact an adult’s small intestine would be around 6.7 metres long! This long tube is squashed up underneath your stomach. This is where your food gets broken down even further so your body can have all of the vitamins, fats, minerals, proteins and carbohydrates from your food. The pancreas, liver and gallbladder all help along the way. Each of those three organs send special juices to the small intestine to help digest the food and ensure the nutrients are absorbed. Each organ produces juice for different reasons – the pancreas makes juice that helps the body digest protein and fats, bile from the liver helps absorb fat into the bloodstream and the gallbladder stores bile until the body needs it. 5 Liver Now the blood filled with all of the nutrients and goodness from your food heads to the liver. The liver filters out all of the harmful substances and waste (sometimes turning this waste into more bile). The liver also decides how much of the nutrients are going to the body straight away and how much needs to be stored. 3 6 Large Intestine Your large intestine is thicker in width than your small intestine and it is almost the last stop for your food. What is now left is just waste as the nutrients have mostly been removed. This needs to be passed through your body and removed – which is why we go to the toilet! It passes through your colon, where your body has its last chance to absorb any water and minerals, and then it moves along, getting harder as the water is removed, creating solid poop! The solid waste ends up at your rectum, where it waits until you go to the bathroom. FUSE 17
