Beast Studio

It's rare for animals to be shy around humans.

The shyer the little camel is, the cuter Liu Wei thinks it is. Although its appearance is a bit rough and far from being compared with the giant panda, its cuteness masters, its simple character can often directly touch the soul and make you fall in love with it.

Wait until the little camel raises its head again.

The phone camera focuses on its face.

Liu Wei smiled and said to the little camel, "Brothers, listen carefully. I have a lot to learn about wild camels. Let's start with this species.

When we think of wild camels, we naturally think of domestic camels and compare them with them.

The origin of domestic camels was obtained by humans through domestication of wild camels, but since their reproduction, their genetic genes have undergone great changes.

According to scientific calculations, the genetic difference between wild Bactrian camels and domestic camels is 2%-3%. From a genetic point of view, the difference is huge. We must treat wild camels as a separate species. "

"No way! Such a big difference!"

"I thought it was just a physical difference!"

"The genes have actually changed!"

"Reminds me of wild boars and domestic pigs!"

"..."

Liu Wei continued: “So I will now treat wild camels as a separate species for popular science.

Let's start with its face.

Everyone should be curious, why can wild camels move normally in windy sand?

The reason lies in some special structures on its head.

When it comes to blocking wind and sand, it can be said that no animal in the world is better than the wild camel!

The hair on the edge of its eyelashes and ears is long and dense, which can effectively prevent wind and sand from entering its eyes and ears. It also has double eyelids. Both eyelids can be opened and closed independently, and it can still remain clear in the diffuse wind and sand. vision.

Do you know what eyelids are? "

The audience was confused.

Basically I have never heard of this professional term.

Liu Wei looked at the barrage and sighed. Sure enough, he only watched the live broadcast to watch the excitement. When cultural common sense was mentioned, everyone got a question mark face.

Liu Wei did not play with the little camel's eyes, fearing that the female camel who was drinking water would think it was hurting her baby and would behave like spitting.

Flip the live camera and focus your eyes.

Liu Wei gently raised his eyelashes and opened his upper eyelids, "If you look carefully at my eyeballs, the eyelids are right in front of my eyeballs.

The eyelids are composed of skin, connective tissue, muscles, glands and conjunctiva. The eyelids are divided into upper and lower eyelids and are an important structure for protecting the eyeballs. Wild camels have double eyelids, which is equivalent to double protection of the eyeballs. "

Liu Wei let go of his hand, blinked his eyes, and almost shed tears.

"Hahaha, it's so difficult for Ah Wei to meet our group of fans!"

"Awei, I still don't understand, what should I do?"

"Laughing and crying, are you going to make Ah Wei angry to death?"

"Awei, I'm a girl, come here and let me blow your eyes!"

"Go away!" Liu Wei said in disgust, and continued to popularize science, "After talking about ears and eyes, let's take a look at its nostrils. There are valves in the nostrils of wild camels. I know you are going to ask what valves are?

I might as well say it directly!

Valve is a membranous structure that can open and close in the organs of humans or some animals. Among human organs, it mainly refers to the valves of the heart. Everyone has four valves in the heart.

The aortic valve connects the left ventricle to the aorta, the pulmonary valve connects the right ventricle to the pulmonary artery, the mitral valve connects the left atrium to the left ventricle, and the tricuspid valve connects the right atrium to the right ventricle.

They all function as one-way valves, allowing blood to flow only from one direction to another but not backwards.

The valves in the nostrils of wild camels play the same role as human heart valves. They can be opened and closed at will, which not only ensures smooth breathing, but also prevents wind and sand from pouring into the nostrils. The water flowing out of the nose can also flow along the The nasal groove flows into the mouth.

At this point, I would like to ask if anyone in the live broadcast room has tried drinking water through the nose?"

"I feel like Ah Wei is digging a hole for us!"

"To be honest, I have done it myself!"

"+1"

"I can only say that the feeling is very...comfortable!"

Liu Wei smiled and said: "Fortunately, it all flowed into the mouth and not into the brain!"

The audience didn't react immediately.

"Wait a minute, Ah Wei, why don't you say something else?"

"Did you just say that our brains were flooded?"

"Damn it, I just realized it!"

"Awei, you are so arrogant. You dare to laugh at the audience and your parents!"

Liu Wei looked at the barrage and smiled: "Just kidding everyone, to lighten the atmosphere.

Let’s continue. Through what I just explained, everyone should have an overall impression in their minds, that is, wind and sand cannot pour into the faces of wild camels, so they can wear them in sandy weather. If they encounter sandstorms and strong sandstorms, When the weather is bad, they will stop to find a safe position, close all the organs in their heads, and then bend their limbs and lie down on the ground to curl up and wait for the sandstorm to pass. "

"I know this, like an ostrich!"

"Sandstorms are generally short-lived and will pass quickly, but they are very destructive!"

"I've seen a lot of TV dramas that show this. When encountering this kind of weather in the desert, following a camel has a high chance of survival."

"Awei, do you think you will encounter a sandstorm today?"

"Pfft~, crow's mouth, can you wish Ah Wei a little bit?"

Liu Wei looked at the weather, "The weather in the Gobi desert changes abnormally. I'm not sure. If it happens, brothers can only pray for me!"

Smiling, Liu Wei was still very calm. He walked to the side of the little camel, pointed his phone at the two newly formed humps of the little camel and took a picture: "Everyone should be familiar with this raised thing! When it comes to camels, The most representative physical feature and the first thing that comes to mind is probably the hump.

Let me take a look at the barrage. How many people understand the camel's hump? "

"I know, it stores water!"

"It can hold a lot of water in there!"

"It's the one that stores water!"

Liu Wei looked at the barrage and shook his head, "Brothers, you are still living in the past!"

The audience was confused about what Liu Wei meant and all raised question marks.

Liu Wei said: "In the past, it was intuitively felt and speculated that the camel's hump was used to store water, but scientific research shows that the main structure of the camel's hump is fat and connective tissue.

It can be understood as storing fat. The hump will also change in size due to the physical consumption of wild camels, but it will quickly return to its original shape when sufficient food and water are supplied.

Connective tissue is composed of cells and a large amount of intercellular substance. The intercellular substance of connective tissue includes liquid, colloidal or solid matrix, filament-like fibers and constantly circulating tissue fluid, which has the functions of connection, support, nutrition and protection. and many other functions. "

The screen of the live broadcast mobile phone is still full of question marks.

"Awei, what are you talking about?"

"I feel like I'm listening to a book from heaven!"

"Awei, forget it!"

"I cry with laughter, I'm sorry, Ah Wei, I have no face to be your fan!"
