Ugly, blood-sucking bugs, leeches, these creatures have been demonized now. It can be adsorbed on the surface of human skin to suck blood to meet its own survival needs. In the process of being sucked by leeches, it is difficult for prey to feel pain, which is often difficult to detect and even lasts for a long time.
How do leeches suck blood? Leech, commonly known as "leech", generally appears in paddy fields. Anyone who has worked in paddy fields should know about this blood sucking worm. This creature feeds on blood, looks as long as earthworms, and most of them are dark. Leech has two suckers at both ends of its body to help it survive by sucking blood.
The mouthparts of leeches are triangular. When sucking blood, they can make a triangular sucking mouth on the skin surface of their prey, thus sucking blood for survival. Leeches can suck blood several times their own weight at a time. Because the leech is round, there is a lot of blood in its stomach.
The strangest thing is that even if this creature sticks firmly to the surface of human body and sucks blood, it is difficult to detect that it is sucking blood as long as it is not seen. In the process of sucking blood, there is almost no feeling, so the success rate is extremely high. Moreover, leeches are extremely vital, even if their bodies are cut in half, they can still survive.
Leeches can't live long. There is such a news that a child in Henan often felt a sore throat, and was finally sent to the hospital by his family for examination, only to find that there was a leech in his trachea. According to the doctor's follow-up examination, it was found that this leech had survived in his body for nearly a year, which really made people feel numb.
An ugly "vampire" who can survive in the human body for a long time is very terrible. Does this news of Henan children also prove that leeches can not only suck the blood on the surface of prey's skin, but also survive in the human body for a long time?
If people who work in paddy fields all the year round are accidentally eaten into their stomachs when leeches are very young, it is really terrible whether leeches will grow up slowly in the human body, and there is a worm in their stomachs that feeds on blood.
In addition, there are some sensational rumors that leeches can not only survive in the human body for a long time, but also enter the brain. This picture makes people feel scared just thinking about it.
For this, it is certain that leeches will not survive in the human body for a long time.
This is because a prerequisite for leeches to survive is to get oxygen. If leeches enter the human body, it is a problem to get oxygen, and it is impossible to survive for a long time. Moreover, if leeches are accidentally eaten in the stomach, they will enter the human stomach from the esophagus, and the stomach will secrete gastric acid and decompose the food in the stomach. Faced with this situation, leeches have nowhere to escape.
Taking children in Henan as an example, leeches can live in human trachea for nearly a year, mainly because leeches can also live in contact with oxygen in human trachea, and they do not enter the stomach, and there is no secretion of gastric acid and other substances to destroy them. Under such conditions, leeches can survive in the human body for a long time.
Although leeches will not survive in the human body for a long time, we should pay more attention to them. Farmers should try to avoid eating raw water when working in rice fields. Raw water often contains a lot of microorganisms, which is quite unfavorable to human health. And there will inevitably be leech larvae and eggs. If you accidentally eat leech larvae, you can't survive in the body for a long time, but if you accidentally live in the nasal cavity and trachea, you will still have endless troubles.
Leeches can be used as medicine. Although leech is annoying, it is a medicinal material that can be used blindly in traditional Chinese medicine, and its medicinal value is very high. According to the book Shennong Herbal Classic, leeches have the functions of promoting blood circulation, removing blood stasis, reducing swelling and detoxifying.
Now there are human footprints everywhere, and there are fewer and fewer leeches in many farmland and rivers, and more leeches are artificially raised for medicine.
How to deal with leeches sucking blood attached to the skin? If you find leeches attached to your skin to suck blood, don't panic, and don't pull hard, it will accidentally hurt yourself and cause serious bleeding and infection. You can roast it with fire or sprinkle salt on the leech, which will make the leech fall off the skin.
Disinfect the wound when leeches naturally shed their skin.
If leeches are found in the nasal cavity and throat, they should go to the hospital immediately once they are found, and taking them out will not cause serious harm to the body.
Conclusion Leeches will not survive in human body for a long time. As long as they are treated in time, they will not do great harm to human body, but this does not mean that they can be indifferent, and they should be extra careful in abandoned paddy fields and uninhabited river ponds.
