What is a...

what is a bruise? Like a bruse on my arm. Whats going on under my skin when I have a bruise?

I think its the blood cells breaking underneath. at least I think so. I read it in a book.

liiikeee...its the blood in your arm that got bruised and its trying to like leave your body. ahhh. nvm. thats probably wrong. sorryyy.

You get a bruise from leakage of blood from capillaries under the surface that have been damaged

small blood vesssles broke I don't know thats totally wrong but I read it somewhere haha

some of your blood cells die
but your body easily and quickly makes new blood cells

When the capillaries, which are the smallest veins, are broken due to injury if the tissue (u get punched in the arn). Those capillaries break and the blood deposits in the tissue where you were punched) and causes the discoloration. As the blood is reabsorbed back into the tissuea, the bruise heals and goes away.
