Why is this the answer?

The answer is heart because this clever riddle uses fun secrets to describe the amazing, tireless organ that keeps us alive. Think of the words in the riddle like clues in a treasure hunt. The first clue calls it A red drum. Your heart is a very strong, powerful muscle nestled safely inside your chest, and guess what color it is? Red, of course! It earns the name drum because it makes a steady, rhythmic sound all day and all night. That sound is your heartbeat, which is like a little thump thump that never stops. Your heart is always beating, which is how it pumps blood to every single part of your body, from your toes to your brain. The heart is the center of your body's circulation system. The riddle then says this drum sounds without being touched. This is absolutely right! Your heart beats all by itself. It is an involuntary muscle, which means you do not have to touch it or remind it to make its noise. It is like an automatic machine that is busy pumping and beating even when you are fast asleep and dreaming. It works hard to make sure you have enough blood and oxygen to run, play, and learn every day. It is an independent organ that does its job without any help from you thinking about it. Finally, the most thoughtful clue is that it grows silent, when it is touched. This part means that when the heart stops beating, its important drumming sound goes silent. As long as a person is alive, their heart is making that wonderful sound. When life comes to an end, the heart stops pumping blood and the drumming goes silent forever. This amazing riddle is a very old and smart one because it uses an everyday item, a drum, to help us understand a very important part of our bodies. It is a wonderful way to think about how valuable your own strong, tireless, and wonderful red drum truly is!
