How does our body work?

Our brain

Introduction

Our brain may not seem like the most interesting part of our body But we actually use it all the time when we are thinking of something or remembering something.

Our brain sits in our thick skull with membranes and fluid around it to protect it. Inside of our brain we have something called a cerebrum which is the biggest part of our brain and The surface of the cerebrum is called the cerebral cortex. Different parts of the cerebrum deal with different parts of the body.

Sometimes we tend to forget things in our brain and that’s called memory. There are two different kinds of memory like short term memory and long term memory but scientists are still trying to figure out how memory works. But they know that short term memory means that you remember things for a short amount of time without rehearsing or practicing it.

The brainstem is what connects to the spinal cord. Also many automatic functions are controlled here like keeping the heart beat, breathing, and digesting food.

Although the brain doesn’t move it needs lots of energy so the energy is sent to the brain by the blood. And the brain actually uses about 20 percent of the body's energy.

The brain is put into two halves. Because thenerves cross when they enter the brain, the left side of our brain controls the right half of our brain and the right side of the brain controls the left half. What each half does depends on whether you're right handed or left handed.
