Why do people have so many tears

What a strange question, people are emotional animals! People always love to be moved, so the tears can't end!

1 congenital 2 acquired more tears to cry 3 disease 4 inner weakness shyness susceptible to external influences crying 5 the legendary god of tears.

Wowhaha.

One day, Tian fell in love with the sea.

But the air prevented them from falling in love.

God cried. Tears fall into the sea, even if you can't love each other.

Heaven will also entrust its soul to the sea.

Since then, the sea is bluer than the sky.

I guess the rain is the tears of the sky.

Similarly! Tears are the sky is raining!

Because people are emotional.

If you want someone to comfort you, it's when you're with someone.

If you have a strong self-esteem and don't like to be seen in tears, that's yourself.

I see that I like such a pull.

If a person has strong self-esteem, he will not cry easily in front of others.

If you want someone to comfort you, it's when you're with someone.

There's no way, because people drink water.

Because we can't really make the heart die, you're still going to be sad.

There will be tears.

Because tears are the preserve of man.

I think people have joys and sorrows.

People have emotional ......

The affectionate ones are called tears.

Relentlessly, that's water 11

Sad. For man is not strong.

Because we have been kind to others, we are tired.

Because people are emotional animals, no matter how strong they are, they have a fragile side, even if she (he) laughs every day, but who knows if she (he) is crying in her heart.

People will shed tears when they are happy, tears when they are sad, and tears when they are moved.

Indeed, people of different classes and ages will also shed tears! The difference is the lightness and severity of the tears.

The transmission of excitement between one neuron and another neurogen in the body is accomplished by a medium ——— a central transmitter. If there is too much of this central transmitter, it can cause too many nerve impulses. To do this, the body produces a corresponding decomposition enzyme to break down excess central transmitters.

Once there are too many central transmitters, the decomposition enzymes cannot remove all the nutrients, and they have to rely on tears to excrete them from the body.

Tears have a function of sterilization, and they can make people vent, and crying will make the sad things pass! Crying, proving that the heart is really broken, crying, it's over, and the next happiness can begin!

Saying goes; Joy, anger and sorrow, human nature. Even if you have a strong personality, you will inevitably have times when you cry bitterly or burst into tears. Moreover, people cry not only when they are sad, but also when they are happy and excited.

The specific reason for crying, or "the hero has tears and doesn't flick", or "tears before flowers, injuries under the moon", the difference between people is huge.

When people are sad, grieved, and broken, they shed tears; People shed tears when they are happy. Tears seem to be a symbol of emotional change, but in fact, tears do not exactly indicate a change in mood. When a foreign object such as dust falls into our eyes, a large number of tears are generated and the foreign body is washed out.

In addition to a large amount of water, there are lysozyme, immunoglobulins, complement system, lactoferrin, -lysin, etc., which have the effect of inhibiting the growth of bacteria. Therefore, tears have another very important function - defense.

Tears come from the lacrimal glands. The lacrimal gland is made up of thin tubular glands and ducts, and it is the organ that secretes tears. The lacrimal gland is located in the lacrimal gland fossa above the outer orbit, and there are two parts:

The upper part is the orbit, also called the upper lacrimal gland, which is larger, and the shape is very similar to an almond, about 12 mm 20 mm; The lower part is the eyelids, also called the inferior lacrimal glands, which are smaller. The lacrimal gland has 10 12 excretory ducts, and the tear is excreted by some of the excretory ducts after it is produced. Under normal circumstances, the tear glands secrete tears during the day, which moisten the conjunctiva and cornea of the eyeball, and stop secreting tears when the person is sleeping.

Tears are weakly alkaline, transparent liquids, in which water is the rest, and the rest are small amounts of inorganic salts and proteosomes, as well as other substances such as lysozyme, immunoglobulin A, complement system, etc.

After tears are produced, they are excreted through the tear ducts. The lacrimal duct consists of puncta, lacrimal tubules, lacrimal sacs, and nasolacrimal ducts. Tears enter the lacrimal duct like a sewer from the lacrimal dot and enter the lacrimal sac through the lacrimal tubule about 10mm long, which is specially used to collect and store tears and prevent tears from flowing out.

The size of the lacrimal sac is about 12 mm 6 mm, and there is a tube 12 24 mm long and 3 6 mm in diameter directly under the lacrimal sac that leads directly to the nasal cavity, which is the nasolacrimal duct, and the tears in the lacrimal sac enter the nasal cavity through the nasolacrimal duct. So when we order eye drops, we should press down on the base of the nose with our fingers, just to prevent the eye drops from flowing into the nasal cavity through the nasolacrimal ducts.

Glasses are the window to the soul, people have feelings! When the human heart endures to a certain extent! It will erupt with tears!

In fact, not only yawning can cause tears, but also when people laugh, sneeze, cough, and vomit, and the reason is the same.

Because people have seven emotions and six desires, people have feelings, people have thoughts, and when people are sad, they will shed tears, and tears are the fluid in your body. [Don't always be sad, be happy.] Walk towards happiness. Adopt adopt adoption!

With an open-minded mind, a confident smile, and the perfect answer, everything is under your control. In the face of any difficulty, think about things simply, and you will get an answer that you are satisfied with. Everyone has something they like!

Love doesn't stop waiting for you at the beginning! Whenever you encounter any answer you want, be quiet, quietly calm your heart, and the answer will be like this!

Human beings are emotional animals, and when people move their emotional glands, they will trigger the brain and the pituitary gland secretes tears, which will flow out.

Because we have eyes, and we have tear glands in our eyes. That's why it led to the serious consequence of tears.

Because people have feelings, because people know pain, because people have an endocrine system to protect their eyes.

Human tears are secreted all the time, flowing on the surface of the eyeball. However, there is very little tears secreted and they flow along the surface of the eyeball and in the tiny spaces inside the eyelids, so you don't feel that the tears are flowing.

However, in the blink of an eye, the tears on the surface of these eyeballs are sucked into the nasolacrimal duct, the sewer of the tears. Don't underestimate this not-so-long tube, it's the only way for tears to reach your nose. The lacrimal glands constantly secrete tears, and the nasolacrimal ducts constantly excrete tears, so people usually do not shed tears.

Happiness will not wait for you all the time, the people who love you and the people you love are not ready to appear, please learn to cherish them.

When a person who loves you deeply changes for you, it is because he loves you, and when you meet someone, he puts away his stubborn temper for you; And because he loves you, he turns your interest into his interest when ......Or because he loves you.

There is no reason to like someone, and there is no regret to give.

They all think it's worth it, as long as they can be with the people they love.

In fact, we all have some such people around us, but (you. I. He hasn't discovered that the person who knows you best will always be by your side to protect you and not let you have a trace of grievances; People who truly love you may not say many things that love you, but they will do many things that love you.

If you find someone like this around you, please cherish .......

Please remember! The stars that can't be picked are always the brightest, and the small fish that slip away are always the most beautiful. The missed movie is always the best, and the lost lover always understands you best.

In this world, everyone has someone they want to find, and once they miss it, they won't come back.

If you fall in love, don't give up easily. It's awkward, maybe you regret it for a while; But you give up, and it may make you regret it for the rest of your life. A life that has experienced love is beautiful, and love that cannot stand the test is not profound.

Beautiful love enriches life, and love that has passed the test is perfect.
