What are mosquitoes stinging and why do mosquitoes stab into human skin?

Mosquitoes have a vasodilating and anticoagulant substance in their saliva, which makes it easier for blood to flow to the bite site. After being bitten by a mosquito, the bitten person** often has symptoms of wrapping and itching. Almost everyone has the unpleasant feeling of being "bitten" by mosquitoes, 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 **, it actually uses 6 needle-like structures to pierce people**, these short needles are the center of the mosquito's edible mouthparts. These short needles suck human blood in the same way that they draw blood; The mosquito also releases saliva containing anticoagulants to prevent blood from clotting so that it can eat peacefully. When the mosquitoes are full of food and drink and float away, all they leave behind is an itchy lump.

However, the itchy sensation is not caused by a short needle pricking or chemicals in the saliva. We feel itchy because of the immune system in the body.

At this point, a substance called histamine is released.

proteins are used to fight foreign substances, and this immune response.

Triggers an allergic reaction at the bite site.

When blood flows to the bite site to speed up tissue recovery, histamine causes swelling of the tissues around the bite, and the intensity of this allergic reaction varies from person to person, and some people have a more severe allergic reaction after being bitten by a mosquito.

Hope it helps!

The most annoying and disgusting creature in the world is probably mosquitoes, and if mosquitoes fly when sleeping at night, it can make people feel collapsedAnd it will also suck blood, and people will wonder why the mosquito's mouth is not very hard, but it can pierce people's **? This is mainly because there is a barb under the mouth of the mosquito, which can harm our **.

First of all, in fact, if we compare the creatures in nature, it is really more fragile, after all, it is soft, and for creatures like mosquitoes, they prefer to suck blood, especially at night, stay in the wild for a night, and the next day get up the body is full of bags, which is to be sucked by mosquitoes and bite, etc., and after the discovery of biologists, the mosquito itself is not hard, but there is a barb under the mouth, which can instantly improve the ability to pierce, The sting is so small that it's almost invisible, but those who have learned about pressure must know that although the surface area is small, the corresponding pressure will be higher.

For example, in ordinary life, a pair of scissors can be good for the area pressure, but it takes a certain amount of strength to pierce some objects, but if it is just a small needle, although it is small, the area that can be contacted is also very fast, but the targeted pressure that can be brought is very large, so it can achieve a good effect, and the same is true for the barbs under the mosquito's mouth.

Especially for summer, many times do not pay attention to closing the windows at night, a lot of mosquitoes will fly in, and the next day I get up only to find that I have some more bags on my body, so it is recommended to light a mosquito coil and close the window before going to bed at night, which can reduce the number of mosquitoes well, and usually pay attention to the hygiene of the house, after all, mosquitoes prefer places with a bad environment, and there are many viruses themselves.

Mosquitoes are creatures that we often see in our lives, especially at night, many times make us cry and laugh, and make us very upset, because the sound of mosquitoes flying is too annoying, and at the same time they will suck bloodHere people will notice that the mouth of the mosquito is not very sharp, so they wonder why the mouth of the mosquito is not very hard, why can it pierce people's **? In fact, it is because the mosquito's jaw has a hook-like spine, which can scrape the surface of the human surface very well**, so as to suck blood.

First of all, let's talk about the problem of pressure, we generally feel that the heavier the thing, the higher the damage to us, which is right, because the heavy thing will generally be larger for the surface area of contact, which will give us more space to feel greater damage, but small things are also okay, because the contact area is directly reduced, which will lead to greater pressure, such as scissors, for the mouth of a mosquito, it is true that the mouth is not hard, it can only be said that it is general, But it has a hook-like barb on its mouth, which is roughly the place where it is chin, which gives a small space and a lot of pressure.

So at this time, mosquitoes can use this hook to break through our surface**, and finally directly lead to**Don't tear it open, but the mouth is very small, and it is only enough for mosquitoes to suck blood, but it is enough for mosquitoes, and I would like to remind everyone here that we must pay attention to personal hygiene in our daily life, especially for the summer has come now, many times there will be a lot of mosquitoes, not to mention the discomfort of blood sucking at this time, and the risk of infecting some diseases.

For mosquitoes are very common, we must pay attention to good hygiene at home, so that we can control a certain degree well, and ensure our health, after all, after being bitten by mosquitoes or sucking blood, there will be a certain amount of pain, and there is itching and uncomfortable, which is very troublesome and requires a certain amount of time buffer.

The human ** is still quite elastic, but the mosquito's mouth is so small, how can it pierce into the human ** to suck blood? I'm going to dissect the mouth of a mosquito.

Because the mosquito's mouth is very small and the straw is very thin, it can easily pierce people's **.

Because the mouth of the mosquito is very thin, you can find the sweat pores on the human **, and you can completely pierce it through this hole.

Because the mouth of the mosquito is very thin, and the human ** is not very tight, it can easily pierce the ** of the human.

The blood-sucking behavior of female mosquitoes is regulated by two fleshy pumps, one of which is located from the mouth to the pharynx, which is used to manipulate the base of the food channel; The other is the pharyngeal pump, which is used to regulate the movement of the digestive tract from the mouth to the mid-thorax, and these two pumps are isolated by the sphincter and the midgut of mosquitoes. When mosquitoes suck blood, they will first explore the surface with a lip flap and puncture it repeatedly, so as to select the most appropriate blood-sucking location, and the selection criteria are mainly based on the distribution density of microvessels in **. When the mosquito sucks blood, it is supported by the lower lip, and then the mouth needle is pierced into the mouth, which is a structure composed of the upper lip, the big jaw and the small jaw that can operate as a whole, and the lower lip left on the outside of the ** is bent inward into an arch shape.

Whenever we enter the hot summer, I believe that you will fight with dust and slag will produce all kinds of troubles, such as many times when we go out, because we are worried about being tanned, we will do all kinds of necessary sun protection measures, and there will be a lot of sweat every day, and finally there are a lot of mosquitoes, we all have such questionsWhy is the mouth of a mosquito not very hard, but it can pierce a person's **? In fact, this has a lot to do with the pressure in our air, so let's analyze it in detail.

Whenever we enter the hot summer, many of us will have such troubles, no matter where we go, those mosquitoes are particularly numerous, such as mosquitoes on the dining table, blood-sucking mosquitoes and that kind of tiny mosquitoes, all kinds of mosquitoes fly around quietly in the air, seriously affecting our normal life, not to mention which blood-sucking mosquitoes, it is generally easy to appear at night, if you don't light mosquito coils or spray some insecticides, it is difficult to fall asleep at night, which will also seriously affect our sleep quality.

We all know that the mouth of the mosquito is not very hard, but it can pierce into the human body, because the mouth of the mosquito is not very hard, so if they want to pierce the human body, then they can only work the mouth, at this time they will increase the strength of the mouth piercing, and the mouth of the mosquito is particularly sharp, especially the kind of sharp-billed mosquito, the area is very small when piercing into the **, so small that you can hardly see it.

In the process of piercing in, a force called strong pressure will be generated, and it is because of this force that the mosquito will pierce into the human body. In addition, there are a lot of pores in our human body, and sometimes we don't notice it, so it is quite easy for mosquitoes to pierce the human body. After we are bitten by a mosquito, a lump will grow on the bite site, which is very itchy, so we need to take necessary measures to prevent insects.
