Why is this the answer?

The answer is ring because this clever riddle uses tricky words to describe something you might wear on your hand every day, like a small, circular piece of jewelry! Let us start with the first clue: "It has no top or bottom." Think about the shape of a simple ring. It is shaped like a continuous circle. If you try to hold a circle, such as a round bracelet or a hoop, you can spin it and flip it over, but it always looks the same. It does not have a definite "top" or a "bottom" side, which is a great clue that helps us solve this puzzle. It is perfectly symmetrical, meaning it is the same all the way around no matter how you turn it. Now for the most interesting part of the riddle: "but it can hold flesh, bones, and blood all at the same time." This clue is a big hint about where the ring is worn. A ring does not hold those things inside of it like a box or a bowl. Instead, a ring "holds" what it is placed around, and that is your finger! Think about what makes up your finger. Your finger is covered in soft skin, and that skin is the "flesh" mentioned in the riddle. Inside your finger, there are little, strong "bones" that give your finger its structure and shape. And running through your finger, just like the rest of your body, is "blood." So, when you put a ring on, it wraps around your finger. The riddle uses a word trick to make you imagine a container, but it is actually describing the circular band that encircles all those important parts of your hand. The ring is worn around the part of you that has all those items, making this riddle a wonderful word puzzle to figure out!
