People's external auditory canal skin has cerumen glands, which secrete a yellowish sticky substance called cerumen, commonly known as "earwax" or "ear cicada". After this substance is dried in the air, some are flaky, and some are like sticky grease. Usually hiding in the external auditory canal can protect the skin of the external auditory canal and attach foreign bodies, such as dust and small flying insects.

Why is there booger?

Because people with life phenomena can breathe, just because of breathing, dust in the air will be inhaled into the nasal cavity, and nasal hairs in the nasal cavity will block dust particles and secrete mucus (secreted by nasal mucosa), which will become boogers after a long time.

Why is there gum?

When we get up in the morning and wash in front of the mirror, we will find that there will always be some gum on the inner corner of our eyes, sometimes more and sometimes less. Maybe you will think that you have washed your face before going to bed, and your eyes are closed after going to bed, so dirty things can't get in. So, why is there chewing gum?

As long as we know the tissue structure of eyelids, we can know. There is something similar to cartilage in our eyelids, which is called "meibomian". There are many meibomian glands in the meibomian. The gland mouth is at the edge of eyelid, close to eyelashes, and the meibomian gland will always secrete an oil-like liquid.

During the day, these oils are applied to the edge of eyelids by blinking to protect the eyes. Internally, it can prevent water from flowing out of the eyes, and externally, it can prevent sweat from entering the eyes.

But when people are asleep, their eyes are closed for a long time, and the oil is still secreted, so the accumulated oil is mixed with the dust that enters their eyes during the day and the impurities in the tears, and then runs to the corner of their eyes to form gum.

A small amount of normal gums is not a disease. However, if the gums suddenly increase, sometimes the upper and lower eyelids and eyelashes will stick together, making the eyes hard to open. This may be caused by eye diseases and bacterial infections and should be treated in a hospital.

Gum problems caused by tooth excrement

Gum bleeding depends on the specific situation. First of all, we should check some symptoms in the mouth, such as a large number of dirty gums, which stimulate the gums to be in an inflammatory state for a long time. Then when brushing your teeth or eating, you will encounter inflamed gums, which will stimulate the inflamed parts and lead to bleeding. This is a local reason. To clean the teeth, clean the gums inside, diminish inflammation of the gums, and stop bleeding when the gums are in a normal state. On the other hand, there are systemic diseases, anemia or blood diseases, and low platelets may cause bleeding in the mouth and gums. At this point, if the local cause is removed and there is still bleeding, it is necessary to check whether the blood flow direction is normal. In addition, it is also related to endocrinology. We have a kind of gingivitis called juvenile gingivitis. 17, 8-year-old and 16, 7-year-old boys and girls should be clean and free from cigarettes and dirty things. However, the hormone level is too high or irritates the inflamed gums, or the teeth are not cleaned, resulting in gums under the inflamed teeth. In this case, clean your teeth, don't eat and give some local medicine to your gums.

excrement

Stool is mainly food residue that has not been digested and absorbed, and also contains other substances metabolized by the human body. Their route is not only stool, but also sweat and urine. There are still some substances that are not fully absorbed by the human body and are useless to the body. If the stool stays in the body for more than 24 hours, the body will absorb some harmful substances, so defecation is necessary for good health.
