What to do if you eat a small bloodsucking mosquito, how mosquitoes suck blood

It's okay, buy a bottle of two-pot head to disinfect, no, I'm going to see a doctor!

Male mosquitoes don't suck blood, only female mosquitoes suck blood, in fact, it should be said that they are stung by mosquitoes. Mosquitoes can't open their mouths, so they won't bite on the **, they actually use six needle-like structures to pierce people's **, and these mouth needles (stylets) form the center of the mouthparts.

These needles suck in blood in the same way that they draw blood; The mosquito also releases saliva containing anticoagulants to prevent blood from clotting, so it can feast peacefully. When the mosquitoes are full of food and drink and float away, all they leave behind is an itchy lump.

The blood-sucking dao mosquito is a female mosquito, and the mosquito's mouthpiece is a stinging mouthpart. It consists of an upper inner lip (dao upper lip pharynx), 1 in the tongue, and 1 pair in the upper and lower jaws, which form an elongated needle-like structure and are contained in the sheath-like lower lip. The upper inner lip is elongated, and the ventral concave surface forms the inner wall of the food tube.

The mouthparts used by mosquitoes to suck blood and bite humans are composed of six needles, which are as sharp as a needle tube and can be easily pierced**, and the responsibilities of these six needles are different.

The outermost two needles in the mosquito's mouthparts are serrated and can be cut like a knife**. The two needles next to each other need to help the mosquito pull it apart and help the mosquito suck blood.

Mosquito blood-sucking is closely related to the regulation of micro-RNA-1174 (miR-1174) genes. Scientists from Southwest University found that mosquitoes' desire to suck blood is controlled by a gene in the body, and when this gene is removed, the taste of mosquitoes will change greatly, and they no longer like to drink blood, but drink sugar water instead; Even if you drink blood, you will have indigestion.

Mosquitoes suck blood mainly by a total of six "needles" in their heads.

The process of a mosquito bite is deceptively simple, just a long tube is stuck into our **. But in fact, the construction of the pipe used is extremely complex. On the outside of the tube there is a protective sleeve that bends backwards when biting and sucking blood.

If you look at the head of a mosquito with a microscope, you can see what the case is protecting. This tube actually contains six needles.

Two of the needles contain serrated protrusions at the tips that mosquitoes can use to cut through**. Since they are so sharp, you won't even feel their presence. The other two needles are used to separate the tissue.

Through the microscope, you can see that it is looking for blood vessels. Receptors on the tip of the needle detect chemicals in the blood vessel and guide it to the blood vessel without any problems. The blood is then sucked into the body as if it were a straw.

After sucking blood to a certain extent, it separates the water from the blood and squeezes it out of the body. In this way, it fills the body with more nutritious red blood cells. While sucking blood with the 5th needle, it will inject chemicals into our body with the 6th needle, making it easier for the blood to flow and be easily absorbed, which is why a bag appears in the place where the bite is taken.
