When you hit a mosquito is it your blood or the mosquitoessential blood?

When you hit a mosquito, the fluid that comes out is primarily the mosquito's saliva, not your blood. Mosquitoes inject saliva into their hosts when they bite, which contains anticoagulants to prevent blood clotting and facilitate feeding. If you crush a mosquito, it may also release some of the blood it has ingested from previous hosts, but it is not your blood that is expelled.
