Respiratory System
Through respiration we take in the oxygen our cells need to transform into energy and our body releases the carbon dioxide it doesn’t need.
There are two processes involved in respiration: pulmonary ventilation and gas exchange.
The organs involved in the respiratory system are: mouth, nostrils, nasal cavity, farynx, windpipe or trachea, bronchi, bronchioles, alvioli, lungs and diaphragm.
Pulmonary ventilation is the movement of air into and out of the lungs. This process is performed by two movements: inspiration and expiration.
During the inspiration movement we inhale. The diaphragm contracts, the chest cavity expands and lungs become wider and larger.
Gas Exchange
Gas Exchange happen in the Alveoli. Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they're microscopic, alveoli are the workhorses of your respiratory system. You have about 480 million alveoli, located at the end of bronchial tubes.
You get Oxygen in your body and in the process of expiration you get rid of Carbon Dioxide.

Subject: Hi, I'm Nick, and I'd Love to Tell You About Madrid!
Hi there,
I hope you're having an awesome day! My name is Nick, and I'm 11 years old. I'm super excited to write to you about this really cool place called Madrid. It's a city in Spain, and it's totally amazing!
Madrid is not just any city; it's the capital of Spain, which means it's a really important place. I learned about it in school, and now I want to tell you all about it.
One of the coolest things about Madrid is the food. Oh my gosh, they have the yummiest food ever! They have these things called "tapas," which are like little snacks you can eat with your friends and family. You can get all kinds of tapas, like yummy olives, delicious ham, and even little sandwiches. And the best part is that they have these cute little cafes where you can sit outside and eat.
Another thing I love about Madrid is the parks. They have this huge park called "El Retiro," and it's like a giant green paradise. You can ride boats on the lake, see really old trees, and even visit a beautiful palace called "Palacio de Cristal." I went there with my family, and we had a picnic. It was so much fun!
Speaking of palaces, Madrid has a real palace called "Palacio Real." It's like a fairy tale castle! You can go inside and see the different rooms, and it's so pretty. I felt like a prince when I visited.
Madrid is also famous for its football. They have one of the best football teams in the world called "Real Madrid." I love soccer, so I was really excited to learn about them. They have a huge stadium called "Santiago Bernabeu," and it's massive! I wish I could watch a game there someday.
And guess what? They have a really cool art museum called the "Prado Museum." Even though I'm just a kid, I thought the paintings there were really interesting. They have paintings from a long time ago, and it's like taking a trip back in time.
Well, that's a little bit about Madrid. I hope you enjoyed hearing about it from me. Maybe someday you can visit this amazing city too. If you have any questions or want to hear more about Madrid, just let me know!
Take care and have a great day!
Your friend,
Nick š

The Digestive System
The digestive system transforms the food we eat into nutrients and passes them to the blood. It also expels the undigested food out of the body as faeces.
How food travels inside your body?
In this picture you can follow the food inside your body.
Here is a video that explains how the digestive system works.
