Can cat hair suck into human lungs How can the structure of the human body be so fragile!

Cat hair is not sucked into human lungs, although cat hair is difficult to clean, but when humans breathe, air generally enters the human body from the nasal cavity, and the epithelial cells of the nasal cavity have cilia, which have a blocking effect on external dust. Visible hairs such as cat hair are blocked by cilia on the nasal cavity. Cat hair is not sucked into human lungs, although cat hair is difficult to clean, but when humans breathe, air generally enters the human body from the nasal cavity, and the epithelial cells of the nasal cavity have cilia, which have a blocking effect on external dust.

Like cat hair, this more obvious hair will be blocked by the cilia on the nasal cavity, particles with a diameter of more than 10 microns in the air, almost all of them will be removed in the nasal cavity, with the secretion of mucus, downward discharge, over time to form nasal feces, unless the owner deliberately wants to suck the cat hair to the lungs, otherwise the cat's cat hair is not easy to be inhaled into the lungs.

If the owner accidentally really sucks the cat hair into the lungs, then there is no need to worry, the human trachea will also be protected by cilia, and because the cat hair is too large, it will still be coughed out in the end and will not remain in the lungs.

In daily life, it is recommended that the owner still needs to comb the cat more, because the cat's own hair loss is still more serious, not timely hair combing, it will cause the cat's hair to fall at home, will be accompanied by the owner of the cat hair inhalation, although it will not cause harm to the human body, but to avoid this situation, it is necessary to comb in time.

Generally speaking, the hair of domestic cats cannot be sucked into the lungs, because people breathe through the nasal cavity when calling, and the nasal cavity is protected by cilia, and the defense mechanism to prevent foreign bodies from entering the respiratory tract is not only nasal hair, such as the turbinate bone that will produce a swirling air flow when calling to prevent foreign bodies from entering. As long as there is no allergy, cat hair has no effect on human health.

<>, you can rest assured that cat hair is generally not sucked into human lungs, so the remarks on the Internet that "if you raise a cat for a year, there will be 100,000 cat hairs in your lungs" is false, and you don't need to care too much.

Why doesn't cat hair get sucked into the lungs?

This is mainly due to the special structure of the human respiratory tract. The process of air from the nostrils to the lungs needs to pass through the nose hair, nasal cavity, nasal cilia and mucus layer four lines of defense, in the process of human breathing, most of the impurities in the air will be filtered out, to ensure that every breath of air you breathe is clean. Normally, only substances can enter our bronchi, and smaller substances will enter our lungs, and the smallest cat hair, there are 400 times more!

Therefore, you don't have to worry about whether there will be cat hair in your lungs. If you want to suck the cat, you can suck the cat (except for patients with cat hair allergies).

Will cat hair be eaten in the stomach?

Although cat hair does not escape to the lungs, there is still a possibility of accidentally eating it into the stomach. Although most of the time, when we have hair in our mouth, we will have a noticeable strange sensation on our own, and we can spit it out on our own. However, if silky hairs are mixed in the food, it is not easy for humans to feel it when they chew food.

Because cat hair is finer and shorter than humans, there may be a small amount of cat hair swallowed into the stomach along with food during our rapid chewing.

But the shovelers don't have to worry, the cat hair in the stomach can generally be excreted normally through feces, and there is no need to worry that we will also have the same symptoms of spitting hairballs as cats.

To sum up, cat hair will not have much impact on humans except for the fact that it will stick to our clothes and furniture. On the contrary, the cat itself is prone to serious cat hairball disease when licking its fur every day, so for the sake of the cat's health, the shovel officer should regularly comb the cat's hair and feed it with hair cream!

Don't be misled, all the people on the Internet who say that cat hair will not be inhaled into the lungs do not say 100% that it will not, that is, they dare not guarantee it, including Academician Zhong Nanshan raises cats, and also recommends pregnant women to raise them early, I will analyze the reasons with you, the nose can be filtered, the trachea will also be filtered, but it is not wrong to break through the nose and enter the trachea to induce sneezing and coughing can be discharged, that is whether it is a good thing to cough and sneeze repeatedly and repeatedly, and then sleep at night without sneezing and coughing, Will the hair of the respiratory tract mixed with phlegm be inhaled deeper into the lungs under the strong force of snoring?

Post-coronary sequelae often have nasal congestion, after nasal congestion, mouth breathing, nose filtration fails, directly into the trachea filtration, what is the efficiency of tracheal filtration? Can 100% coughing and sneezing be discharged? Then there is nasal congestion and snoring, and there is news that chili peppers can choke on the lungs when eating, and who can guarantee that the cat hair in the respiratory tract will not be inhaled into the lungs?

There is also news that owning a cat leads to lobectomy yard state, and then experts agree that fungal infection, 100% fungal? Expert, can you guarantee that it is not a long-term cat hair that cannot cough up, resulting in inflammation of the lung lobes, inflammation of the lungs, its own lesions, unable to defend against bacteria, and there is haze and dust pollen pollution everywhere when you go out of the house, and then the home should be able to purify the lungs of a day's hard work, but I didn't expect that the danger is more serious than the pollution source outside?
