The brain is the most amazing part of the body. It is the boss that dictates everything you do. In other words, your brain enables you to think, feel and move in all manner of ways. It’s like a command center that’s running all the time that’s super powerful. It is your brain that assists you in learning new things each day while recalling the things that you already know.
Your brain consists of special tiny units known as neurons. So, there are close to 100 billion of these cells working in unison! Those neurons are what allows you to perceive the world. They allow you to digest what you see, hear and touch. Your brain, too, is involved in how you feel. It makes you feel different emotions, say happiness when you play with your friends, or sadness when you lose something valuable!
There are lots of fun and cool things you can do with your brain. You know what you can do? Solve puzzles, write thrilling stories, sing favorite songs, play sports with friends. Not only that but then your brain is so powerful that your brain can also make you create beautiful art to invent new things and even explore the mysteries of space! What your brain could do is limitless.
Your eyes are also amazing at adapting to the light conditions surrounding you. When you walk from a bright room into a dark room, for example, your pupils (the little black dots in the center of your eyes) adjust themselves. They shrink in bright light, which helps to protect your eyes, and expand in dim light so that you can see better.
Your heart is a pump with four chambers. It receives blood from various areas of your body and pumps it to your lungs to receive fresh oxygen. When the blood is filled with oxygen, your heart pumps it back out to all the cells in your body. This is extremely crucial as it helps in maintaining the organs as well as the muscles in the body.
Your heart is too strong and can endure; If something goes wrong, it can absorb a lot of stress and keep going. One of them is if one of the blood vessels that brings blood to your heart is blocked, you get a heart attack. It’s pretty serious, but with medical care and doctors, they can almost always be saved and pump blood again.”
Your outer ear gathers sound waves and funnels them down a small tube, the ear canal, into the eardrum. As the sound waves reach your ear, they vibrate your eardrum, and these vibrations then make their way to the middle ear. Three tiny bones middle ear amplify the vibrations. These bones then transmit the vibrations to the inner ear. In the inner ear, the vibrations are transformed into electrical signals that the brain can interpret as sounds.
