Oops excuse me. Oh
00:00:11
Hello friends. Have you ever wondered where does the food go once it enters your body?
00:00:13
Sorry, well worry no more cuz I'll tell you all about the human digestive system
00:00:20
oops
00:00:28
Come on! What are you waiting for? Zoom in!
00:00:30
Digestion is a simple process where large insoluble food particles..
00:00:35
..are broken down into smaller water soluble molecules.
00:00:40
So that they can be absorbed by blood and give energy to different parts of our body.
00:00:45
The process of digestion has a few stages and I'll take you through all of them.
00:00:51
Come!
00:00:57
Chewing is the first stage of the digestive system.
00:00:58
When you chew your food, the food particles break down..
00:01:02
..into little pieces that are easier to swallow.
00:01:06
The saliva which contains a lot of enzymes mixes with those food particles..
00:01:10
..and helps break down those food particles even more.
00:01:16
Once you have completely chewed your food..
00:01:20
..the tongue helps to push the food particles down your throat.
00:01:23
This process is called swallowing.
00:01:27
The food travels through a long pipe called esophagus, also known as the food pipe.
00:01:30
When the food particles have travelled through the food pipe..
00:01:38
..their next destination is the stomach where those particles hang out for approximately 4 hours.
00:01:42
The stomach releases a lot of acids and enzymes which further break down the food particles.
00:01:50
So that these particles can be absorbed by your body.
00:01:56
An enzyme called pepsin present in the stomach helps break down the proteins.
00:02:01
Oh, and a lot of bacteria are killed by our superhero, the stomach.
00:02:07
So that we don't fall sick.
00:02:13
Destination next, the small intestine.
00:02:16
Once the food particles reach the small intestine..
00:02:20
a lot of juices from the liver and pancreas help break down those particles.
00:02:23
The liver secretes bile which helps break down fats.
00:02:29
And the pancreas releases other enzymes to help digest all kinds of food particles.
00:02:33
Now that the food particles are broken down,
00:02:40
the small intestine absorbs them and transfers them to our body through blood.
00:02:43
The particles that are not absorbed by the small intestine reach the large intestine.
00:02:49
Now the large intestine absorbs water and other particles..
00:02:56
..and sends the waste material out of your body.
00:03:00
Trivia time!
00:03:04
Did you know that our large intestine produces antibodies that help us boost our immunity?
00:03:07
When your face becomes red due to blushing, the lining of your stomach becomes red too.
00:03:13
So eat healthy, digest healthy and live healthy.
00:03:19
Tune in next time for more fun facts.
00:03:24
This is me zooming out.
