A Brand-New Body

                    But the mosquito acts as if it is aware of this and injects an an-
               ti-coagulant secretion into the wound from within one of its sharp
               knives. Thus the enzyme in the blood is rendered ineffective and
               the clotting stops.
                    What’s more, with this secretion the mosquito even gives a
               local anaesthetic to its victim, numbing the area it cuts into.
               Accordingly the victim is not aware that its skin has been cut and
               its blood sucked. It is this secretion that causes an allergic reaction
               in the skin and causes the skin to itch.
                    In the few seconds in which the above takes place, a person
               cannot even realise that he has been bitten by a mosquito.
                    A female sucks about 2.8 mg (0.0001 ounce) of blood in one
               go, and this takes about 2.5 minutes. When the sucking finishes,
               the blood is sent to the midgut by suction pumps located in the
               fore-section of the digestive system. The abdomen fills with blood


                                    In a mosquito’s sucking tube there is a cutting
                                    mechanism consisting of 6 knives. 4 of these knives
                                    cut into the skin and the other 2 join to form a hol-
                                    low tube, which the mosquito sticks into the tissue
                                    it has cut and sucks out the blood.
