how come when u get hit your skin swells up, or it gets a bruise?

Answer 1

A bruise forms because blood vessels under the skin burst. The discolouration you see is blood under the skin.

Answer 2

When you are injured, the tissue is crushed. This disrupts the normal structure and connections of the skin, including blood vessels, lymph vessel and connective tissue. You bruise because of blood leaking out of the vessels. You swell due to leakage of fluid into the tissue from blood and lymph vessels, but also in response to the injury. When tissue is injured, platelets are activated (among other cells) that release chemicals that recruit other cells to come and repair the injury. These chemicals also allow even uninjured vessels to "leak" so that inflammatory cells can get to site of injury. But this also leaks more fluid into the tissue causing swelling.

Answer 3

Slice a raw onion and place it over the bruised area, but do not place it over broken skin.
