1. 0:00Drum, drum, feel the beat. Books are
2. 0:02smart, let's read and play.
3. 0:03>> SMART BEATS ALL DAY.
4. 0:07>> WOW, DAD EATS so fast. But, have you
5. 0:11ever wondered what happens to the food
6. 0:13after we eat?
7. 0:16Where? On the food? Looks like we're
8. 0:19about to go inside Dad's mouth. Look.
9. 0:23What are those big doors? Those are the
10. 0:25lips. They help keep food inside the
11. 0:27mouth and help you speak and smile.
12. 0:29Let's go inside.
13. 0:38Woah, look at how huge the tongue looks
14. 0:40from down here. Yeah, and look at look
15. 0:43at those bumps. Those are the taste buds
16. 0:46that help us taste food.
17. 0:48Without it, ice cream, pizza, and
18. 0:51chocolate would all taste the same. The
19. 0:54tongue has thousands of tiny taste buds,
20. 0:56so that's how we know if something is
21. 0:58sweet, salty, sour, or bitter. Exactly,
22. 1:03but tasting isn't its only job. Really?
23. 1:06What else does it do? When we chew food,
24. 1:09the tongue moves it around the mouth and
25. 1:11pushes [music] it toward the teeth. And
26. 1:13when we're ready to swallow, the tongue
27. 1:15pushes the food to the back of the
28. 1:17mouth.
29. 1:18That's not all, the tongue also helps us
30. 1:21talk. [music] Wait, you mean we need it
31. 1:23to say words? Yep, try saying la la la
32. 1:27or ta ta ta. Your tongue is working
33. 1:29hard. You're right. My tongue is moving
34. 1:33all over the place. So, the tongue helps
35. 1:36us taste, chew, swallow, and speak. Hey,
36. 1:40look up there. What's that little thing
37. 1:43hanging at the back? Oh, that is called
38. 1:46the uvula. The uvula helps us make
39. 1:48sounds when we talk and helps keep the
40. 1:50back of the mouth comfortable.
41. 1:52Comfortable? Yes, the uvulas keep the
42. 1:55throat moist by producing a little
43. 1:58saliva. Saliva? What does that mean? It
44. 2:01helps make food soft and wet. But where
45. 2:04does saliva come from?
46. 2:06It comes from tiny organs called
47. 2:08salivary glands. So they are like little
48. 2:11saliva factories. Yes, they make saliva
49. 2:14mouth when we need it. Do they only help
50. 2:16us eat? Nope. Saliva also helps protect
51. 2:19our teeth by washing away food pieces.
52. 2:23>> [bell]
53. 2:25>> And it also helps us taste food. Saliva
54. 2:27carries flavors to our taste buds. So
55. 2:29our mouth needs saliva to taste, [music]
56. 2:32chew, swallow, and stay healthy.
57. 2:34Exactly. Let's continue exploring. Wow,
58. 2:38the top of our mouth has different
59. 2:40parts. That's right. It's called the
60. 2:42palate
61. 2:43>> [music]
62. 2:43>> and it has two parts, the hard palate
63. 2:46and the soft palate. This is the hard
64. 2:48palate. It's the strong [music] bony
65. 2:50part at the front. It helps with
66. 2:52chewing, speaking, and separates the
67. 2:54[music] mouth from the nose. This is the
68. 2:56soft palate. It's flexible and helps
69. 2:59with swallowing and speaking.
70. 3:02Together they help us eat and talk every
71. 3:04day.
72. 3:07Every part of our mouth has an important
73. 3:09job. Wait, what is that black spot?
