Hello, welcome to Mayrim's Library. 00:00:00
Today I'm talking about the digestive system. 00:00:05
Our digestive system breaks foods down into small particles called nutrients. 00:00:13
All our muscles and organs need these nutrients. 00:00:20
They give us energy and help us grow. 00:00:24
Once the digestive system has extracted the nutrients and hair right of the waist. 00:00:27
The parts of the digestive system are 00:00:35
Mouth 00:00:38
Her food is broken up by the teeth and mixed with saliva by the tongue. 00:00:39
Esophagus 00:00:46
Food goes down this tube to the stomach. 00:00:47
Stomach 00:00:51
Her gastric juices make the food into a trick liquid. 00:00:52
Small intestine, there are lots of blood vessels nutrients pass into the blood here. 00:00:56
Large intestine, the waste faces down here, water go out into the body and the waste become harder. 00:01:03
Anus, the waste callus faces lift the body here. 00:01:13
Other day more! See you later alligators! 00:01:20
