The mosquito’s six “little stingers”
The mosquito’s mouth is actually composed of six slender little stingers. Of course, it cannot be seen with the naked eye. This can only be seen under a microscope. Each of these six little needles has its own mission. The two serrated needles in the front are called "jaws", which are sharp tools for poking open the skin. The two "upper jaws" at the back are responsible for fixing the body, clearing and finding obstacles to blood vessels. After finding the blood vessel, it will first use the needle in the middle to spit out saliva (release the anticoagulant ) to prevent blood coagulation. The last needle is what it really does. It can automatically search for the location of the blood vessel. During the process, the virus is also injected into your blood.
The mosquito is also a glutton. Although it only takes about 45 seconds to eat a full meal, it will continue to eat until its belly swells several times its body size. When it is full, it will separate the blood and water in the body and expel it from the body. Meimei consumes red blood cells .

The bulge formed after a mosquito bite
When the mosquito bite flies away, the human skin will feel itching and stinging. This is an allergic reaction caused by the residual saliva of the mosquito. Because the human body will release fluid and cells to the bitten site and activate the body's defense mechanism, a bulge will form at the mosquito bite.
If you find that the bulge this time is larger than usual, then you are honored to have met a newbie who is not very skilled in the business.
