What are you waiting for? The digestive system and digestion
Hello friends, and welcome to a new Happy Learning video. Today we are going to learn about the digestive system and digestion.
So that our body can make the most of the food we eat, it must first transform it into a simpler substance called nutrients. These nutrients are then transported by our blood around our body to be used and converted into energy. This food transformation process is called digestion and is done by the digestive system.
The digestive system is a very long tube threw which food travels and is made up of the following parts:
The mouth; this is where the digestion journey begins. The teeth both chop and grin up the food we eat. Once it has been made into a ball, it is pushed down the food pipe, to the pharynx.
The pharynx is a cavity which shares the digestive system with the respiratory system. It is from the pharynx that the food goes to the esophagus.
The esophagus is a soft muscular tube that moves food further down to the stomach.
The stomach is a widening of the digestive tube. It creates a movement which allows food to mix with gastric fluids. Once this process has been done, it then travels to the small intestine.
The small intestine, is called small because of its width not its length. It's actually much longer than the large intestine, measuring up to 7 meters in length, almost as wide as a football goal from post to post. Well it is here, in the small intestine, were the food digestion journey ends. Now it is up to fluids processed by two glands, the liver and the pancreas, to finalize the transformation of food into nutrients.
Once the food is converted into nutrients, they then traverse the small intestines walls and filter into our blood where they are then made good use of, by all of our bodyยดs cells. But what happens to all the food that our body doesn't need? All that, such a fiber, for example, is transferred to the large intestine.
The large intestine is a thick tube which accumulates substances which our organism cannot digest and is also where water from these substances is absorbed. These substances then form the fecal matter, or what we call poop, which comes out of the anus. Agghh, it sounds a little bit discussing but that's how our body works.
Anyway friends, I hope you found the digestion system and digestion as interesting as I did.
See you later, and don't forget to subscribe to Happy Learning.
Mushroom foragers rejoice! Your lives just got a whole lot easier! Now, we can farm four mushrooms that used to only be found in the wild: morels, huitlacoche, chanterelles, and truffles. Here's why it took so long.

Have you ever heard of the law of inertia? In this Newton's First Law of Motion video for kids, you will learn about why objects either move or don't move. The first law of motion, or the law of inertia, states that objects at rest will remain at rest unless something else moves that object. It also states that an object that is moving will keep moving until something stops it.
When it comes to an object at rest, think of anything around you that isn't moving. A pillow, a book on the desk, or the desk itself. They will stay unmoved unless you, or something else, moves it. As far as objects that are moving, think of a ball in the air. Eventually the ball will fall because of gravity and air resistance. However, if it were in space, it would keep moving forever at the same speed unless it hits something or something hits it.
Speaking of gravity and air resistance, these are two natural forces that affect an object's motion. Another is friction. If you roll something across a flat but uneven surface, that object will eventually stop because of friction. Say, however, you roll something along a flat and even surface, such as perfectly smooth ice. In this case, the object you roll may not stop for a much longer amount of time because there is much less friction to stop its motion.
We hope you and your student(s) enjoyed learning about Newton's first law of motion! If you want to learn even more, head over to our website and download one of our many free lesson plans about the law of inertia, full of activities, worksheets, and more!

Itโs obvious that knowing more than one language can make certain things easier โ like traveling or watching movies without subtitles. But are there other advantages to having a bilingual (or multilingual) brain? Mia Nacamulli details the three types of bilingual brains and shows how knowing more than one language keeps your brain healthy, complex and actively engaged.

Did you know that some tortoises can live for 150 years
Some of the animal species that live the longest are reptiles. This is the case for the tortoises that live in the Galรกpagos Islands, who are able to live for 150 years. But this giant tortoises are threatened by humans. For many years, humans have hunted them for their meat and the rich oil that they contain. Also, many of the spaces they live in have been destroyed and the water of the sea of their habitats has been contaminated. Letโs hope that all this changes and we are able to look after and protect nature
Did you know that reptiles are very ancient?
Without doubt, these animals are among the jewels of evolution of the animal kingdom, crocodiles have been existing for 250 million years and they are one of the animals that still have many similarities with dinosaurs. But they are not the only ones, look at this Komodo dragon, it has similarities to a dinosaur, doesnโt it?
Did you know that the longest snake in the world can be 10 meters long and the smallest one is 10cm?
The longest snake is the reticulated Indonesian python which can weight up to 100 kilos. It feeds on birds, rodents and other reptiles but the biggest ones are able to eat entire monkeys, deers and wild pigs!
The truth is that they are a bit scary.
The one that canโt possible scare you is the silk snake which is the smallest one in the whole world and itโs only a maximum of 10cm long, this small snake are in danger of extinction, since it only lives on one island called Barbados. Humans have destroyed 95% of the forests on this island and our small little snake doesnโt have any place to live. What a shame!

Improved math is a channel created to provide additional instruction on essential math concepts. Iโm passionate about math and I know first-hand how important math concepts are in the real world.
Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills. These math videos are designed to help teach yourself math or provide self-study math tools to assist when additional instruction is needed. Teaching math and learning math has changed the way many students learn in this virtual environment. Having on-demand math videos can provide math tutoring needed when children are not able to get help from their teachers after school hours or when trying to do math at home.
The library of math tutorials that I create can also be used as supplemental instructional material for homeschool math. Each full-length video comes with a subsequent knowledge check or math practice problems which serve as a virtual math topic worksheet to test your understanding of each skill. These videos can be paused to work out the problems on your own, then unpaused to check your answers. All of these videos can be found under the Knowledge Check playlist.
I also have a library of shorter videos (less than 1 minute in length - shorts) that are quick math tips and tricks on basic math topics. Some of these short math help videos include problems that you can work on yourself and submit your answers in the comments. They are all listed under my Math Tips and Tricks playlist.
Improved math is creating more videos every day to cover topics from 4th grade, 5th grade, 6th grade, and 7th-grade math. The videos focus on fractions, basic math operations, geometry, and ratios but more topics are being added all the time. If there is a specific topic you would like to see covered, drop me a comment in one of my videos and let me know!
Free math help videos will be posted every Thursday and Friday. For additional math resources, check out my math help website at improvedmath.com where I post math worksheets and answers along with additional context on math basics.
Thanks for watching my channel.

What does Newton's last law of motion state? In this Newton's Third Law of Motion video for kids, you will learn the answer to that question and much more. The third law states that for every action, there is an equal and opposite reaction. What does this actually mean?
Think of a rocket. The exhaust from an erupting rocket moves downward while the actual rocket moves upward. Another example is found when a cannonball shoots out of a cannon. The cannonball shoots forward as the cannon moves backward. Because the cannon is so much heavier than the cannonball, it doesn't look like it moves very far, but the reaction is still equal in the amount of force.
One last thing. Have you ever tried to move heavy furniture? You may have noticed that it starts out kind of hard to move. However, as you start to move the heavy object, it gets a little easier. The friction that happens is sliding friction, which is the same sensation you get when you rub your hands together really quickly! Notice how your hands get warm? That's why!
We hope you and your student(s) enjoyed learning about Newton's final law of motion! If you want to learn even more, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

Finance and capital markets on Khan Academy: Interest is the basis of modern capital markets. Depending on whether you are lending or borrowing, it can be viewed as a return on an asset (lending) or the cost of capital (borrowing). This tutorial gives an introduction to this fundamental concept, including what it means to compound. It also gives a rule of thumb that might make it easy to do some rough interest calculations in your head.
