How does it work - Digestive System

-

 





The digestive system is an integral part of the human body. In this passage, I will write about how the digestive system works. 

Let's say a hamburger is consumed. The burger is chewed by the teeth in a person's mouth and broken down into a paste. The saliva moisturises the paste, and then the food enters the oesophagus. The oesophagus is what connects the mouth and the stomach. The muscles in the oesophagus wall contract and relax to push the hamburger paste down to the stomach. 

When the food reaches the stomach, the food paste mixes with the stomach acid. The digestive enzymes break down the food particles. From the stomach, the food reaches the small intestine. The small intestine is a 7 foot and 23 inches tube coiled up , and it provides nutrients to the blood. The enzymes in the small intestine digest the protein, carbs and fat. 

Finally, the food passes to the large intestine. The bacteria feed on the remaining nutrients, releasing more nutrients to the blood. The water is drawn from the paste, which leaves the faces, which is then excreted from the body. This is how the digestive system works. The next write-up will be on how the enzymes work.

  Dear grandpa, My 9th birthday is coming up very soon, so in this letter that I am writing to you, I am going to tell you what I wish to do on my 9th birthday. (from morning to evening). When I wake up in the morning, the first thing  I will do is shout "It's my birthday!" Then I will go brush my teeth like I usually do. Then I will so some chitchatting with my parents for 5-10 mins, and then I wish to head to IHOP (a pancake place) to have breakfast.  After having breakfast, we will go home and I will read a book. In the afternoon, after having lunch which might be paneer and pulav that I'm hoping my Mother will make for me, I wish for my parents to take me to the mall so  I can get a hoverboard, a keychain, a soccer ball, and a LEGO set. After doing those, we will head home so my parents can rest for a while, while they do so I can do some drawing. In the evening we will head to the Living waters church to have some fun, worship, and have a big feast! I am looking...

How does it work - Maglev Train & Scrap Yards

  Have you ever been on a maglev train or worked in a scrapyard and wondered "How do these things work?" I will write about how maglev and scrap magnets get into action. The maglev trains and scrap magnets work by using electromagnets . The maglev train has U-shaped undercarriage which gets attracted by the track due to magnetism, so the train moves along the rails. There are guidance magnets in the train which include magnetic repulsion; they help direct the train to either left or right, or stop the train from crossing the tracks and falling down. The driver is not the only one driving the train! In fact , there are levitation magnets which have computers controlling them in order to slow down the train, keep it on the track, and move the train. In a scrapyard, there will be a crane with the magnet which picks up car scraps. It also has an iron disc which is armored with an electric coil to pick up the scraps. It has a switch to turn on so the magnet works just like ...

Dolphins

  Dolphins are very intriguing creatures. In this passage, I am going to explore some fascinating facts about dolphins. The first remarkable fact about dolphins is that they are really smart. A dolphin's trainer might use hand signals to represent objects. For example, the trainer would throw a ball into the water and signal, "Is there a ball?" The dolphin would respond with a "yes." Then, the trainer might point to a broken vase and signal, "Is the vase broken?" The dolphin would answer "no." Dolphins are intelligent enough to remember the hand sign for an unbroken vase and respond correctly. The another remarkable fact about dolphins is that they can communicate with each other, just like humans. But instead of using English, they rely on motions and sounds to communicate. For example, if one dolphin puts its flipper on another dolphin's back, it means they are friends. If two dolphins jump at the same time, it shows that they are bon...
