The female mosquito injects saliva which contains proteins (anticoagulants) that prevent your blood from clotting. She sucks your blood into her abdomen.
After she has bitten you, some saliva remains in the wound. The proteins from the saliva evoke an immune response from your body. The area swells (the bump around the bite area is called a wheal), and you itch, a response provoked by the saliva. Eventually, the swelling goes away, but the itch remains until your immune cells break down the saliva proteins.

Because females have to bite in order to reproduce. Males don't bite. So, avoid the females and you'll be fine. :)
Edit: Sorry, I misread your question. They itch so much because we're allergic to their bites. It's a small allergic reaction.

they inject something to make you bleed better so they can sip it up faster.
