You asked us, "What happens when you get a concussion?"
 
Our brains are the consistency of Jell-O. Luckily they're encased in bone, wrapped in membranes and are floating in fluid. They're also one of the best-protected organs in our body. Until we get whacked on the head or violently tossed around.
 
Then those delicate brains can end up bumping and twisting around in our skulls.
 
And one result might be a concussion. It's a traumatic injury that at least temporarily alters the way our brains work.
 
That's because nerve cells can get stretched, affecting their ability to send and receive messages to and from the rest of the body.
 
And those protective membranes surrounding our brains? Well, they can tear. That allows toxic substances to leak into brain tissue, causing cell death.
 
Like any other bruised flesh, the brain might also swell during a concussion.
 
And without a whole lot of room to expand, it can end up pressing against the skull. That can cause even more damage.
 
Multiple concussions add up over time, leading to problems with memory loss, depression and even dementia.
 
So today's lesson? Be careful with your Jell-O brain.
 
Mmmm ... Brains! Brains!

    I think this is good to know because a concussion can lead to bad things. You have to try hard to protect the brain because even though it is one of the best protected organ in the body, it is still prone to damage. That is why you have to be careful when you play physical sports.
    Why does bruised flesh swell?
    Answer: Bruised flesh swells because flesh is not that strong.

    When you get a concussion, it is really bad because you can die. It is when your brain is being messed up and you can get into really bad trouble when you are in a concussion. I really feel bad for the people when they get concussions. It is really bad and I hope that these people can not get hit in the head really hard.

    Bruised flesh swells due to a rush of blood to the bruised area. Since the blood levels are so high, the area swells. It seems to be quiet an efficient way to heal bruises.

    Bruised flesh swell's because it is not strong and nothing supports the bruise so it swells up.

    Bruised flesh swells because it is not being protected and it is weak enough to get bruised quickly.

    I think it gets brused from bounceing around in your brain from being tossed around. Lots of football players get concoshions and things like that
