How Do We Grow?

How Do We Grow?

Humans are built to grow, with bones that get bigger if we eat the right things and make sure to get enough sleep. Growth is due to our body cells, which are constantly growing and dividing into new cells. When we eat, our cells take in food and grow bigger. Each cell then divides into two cells, which divide in turn, into more cells.

As the number of body cells increases, we grow. The cells that make up our bones, for example, divide to make new bone cells, causing bones to grow. This also occurs with cells that make up other parts of the body. When we are about 20 years old, our plan for growing taller is completed.

And don’t forget that “growing” doesn’t just have to refer to getting taller. As we get older, we also grow smarter and more knowledgeable about the world. Growing allows us to take the time we need to experience the world and learn about the things we need to do to survive.

The different types of growth that you go through are meant to prepare you for being an adult. Our growth makes it possible for us to do new things as we get older that we couldn’t do before, which includes everything from driving a car, to making important decisions, to taking care of your own family.
