hi we are here today to teach your about the digestive system
oh yes please!
when you eat the food starts off in the mouth because your saliva can break down the food into chemicals called enzymes.
Once your food is broken down it moves through your esophagus, which is the pipe that connects your mouth to your stomach. this is called peristalsis.
next it moves into the stomach. in the stomach it is broken down a second time by acids and powerful enzymes.
then it moves into the small intestine where its broken down for the third time by enzymes released from the pancreas and the bile of the liver.
anything that is left in the small intestine moves to the large intestine. the large intestine is also know as the colon.
the large intestine or the colon is such an interesting part of the body. did you know that irts up to 5-7 foot long!
also it can take up to or even longer than 36 hours for waste to travel through the large intestine!
once the food has travelled through the large intestine it exists through the rectum and the anus.
and thats how the digestive system works. we hope you liked it. bye
