the takes • from the air to the blood

• the circulator carries the nutrients and the oxigen to• your cells• the digestive trasfrom the food we eat into

nutrients • and passes them to the blood

that happenst to food as it travels

How food travels inside of your body 1Digestive begins in your mouth. Your teeth grind the food and your tongue mixes it with saliva from salivary glands.2 next, the bolus passes down the pharynx and the oesophagus and into stomach.3the stomach secretes substances called gastric juices, which are mixed with the bolus and from a paste called chyme.4chyme reaches the small intestine, where it mixes with other juices from the páncreas, the liver and the small intestine itself, to become chyle.5the remains of food that has not been absorben in the smaler intestien continues its journey to the large intestin. There, wáter is absorbed and the remains are tramsformed into faeces and wait in the rectum to be expelled from the body through the anus.
