00:00:00,240 --> 00:00:19,559
The digestive system. Our digestive system breaks food down into small particles called nutrients. All our muscles and organs need these nutrients. They give us energy and help us grow.

2
00:00:19,559 --> 00:00:27,559
Once the digestive system has extracted the nutrients, it gets rid of the waste.

00:00:27,559 --> 00:00:37,560

00:00:44,560 --> 00:00:51,219
Stomach. Here, gastric juice makes food into a thick liquid.

Small intestine. There are lots of blood vessels.

7
00:01:01,280 --> 00:01:03,880
The nutrients pass into the blood here.

8
00:01:05,000 --> 00:01:10,900
Large intestine. The waste passes through here.

9
00:01:10,900 --> 00:01:19,900
