Mosquitoes have a 6-tube system in their "snout". It's a big big needle with 6 parts to it. 4 of those parts are used to pierce the skin of the human. The other 2 parts are 2 tubes. One of those tubes sends saliva from the mosquito down into the human. The other sends blood up from the human into the mosquito.
