What are some of the structures that make you feel that the human body is really an incomparably del

The brain, which is so small, can control the whole body and think. If it hurts a little bit, it's amplified a lot more to our body, so it really makes me feel very subtle about the human body.

I think the structure of the human body is a very delicate thing in the human body. There are teeth, gums, tongue, upper chamber, lower chamber in the mouth, and humans can feel the temperature and taste of food just by relying on these structures, and most importantly, they can also chew, which makes me feel extremely delicate.

I think the bones of the human body are a very delicate thing, they can regenerate when they are broken, and they are very hard.

Hair tissue, why does my hair fall out a lot and grow out very slowly, but my hand hair and foot hair grow back in less than a week after shaving? It's really amazing.

I think the bone structure of the human body is very exquisite, the bones have the ability to regenerate, and the bones can support hundreds of pounds of the body, which is very exquisite.

I think the human kidney is very delicate, it is like a precise filter, filtering out the useless things and leaving the useful things behind.

If you want to say that it is extremely subtle, it must be the eyes, they can see things, and they can distinguish colors, which is really exquisite.

I think the human brain is very subtle, it can think, it can have thinking things, but the form feels no different from tofu.

I think it's amazing how the brain is structured, a solid liquid that can command the body to do things.

The blood in the body is very delicate, can circulate indefinitely, and does not require power.

I think the bones of human teeth are amazing, teeth and bones are so hard, but a little force on them every day can change their shape.

The three highs and five lows of the face, really, some people are very comfortable to look at, and the bones are good.

A man's beard struck me as wonderful, so why would it grow the next morning after shaving at night?

Muscles, the principle of leverage.

Eye, Principles of Optical Imaging.

There are: the principle of levers, nerve fibers insulated from each other, convex lens imaging, the mechanical structure of bones, the insulation of fat, the negative pressure of the joint cavity, the valves in the blood circulatory system.

Arm stretching, heart transfusion,

Muscles, the principle of leverage.

Eye, pre-dust principle of optical imaging.

There are: the principle of leverage, nerve fibers insulating each other, convex lens imaging, the mechanical structure of bones, the macro brother of fat insulation, the negative pressure that closes the pure joint cavity, and the valves in the blood circulatory system.

When I was studying biology in high school, I listened to the teacher talk about the evolution of species and the laws of heredity, and I always felt that I was talking about something very distant.

A bird on a small island in Africa, a pea in a monastery in Europe, or a biologist who can't tell the difference between red and green socks......

In recent years, due to the needs of work, I have been constantly exposed to the knowledge of biology, and I am more and more amazed by the exquisite design of natural selection.

You know, we are the descendants of batches of survivors who have survived the harsh living environment, and our bodies have evolved over tens of millions of years, and each structure has a unique role.

Take fat as an example, this is the sworn enemy of many beauty-loving girls or fitness enthusiasts, and excess fat will indeed make people more susceptible to chronic diseases such as slag three highs, diabetes and cardiovascular disease.

But the amazing thing is that in the process of human evolution, fat is an extremely valuable energy substance. In primitive societies where hunger was often necessary, the human body ate a lot of food when it was available, and the body temporarily stored glycogen and fat for the time being. Never use fat until it is in a pinch.

This is also the reason why many people fail, fat is originally a "combat resource" used to save life, how can it be consumed by you after exercising for an hour or two. Our ancestors survived by this mechanism, how can it be so easily changed.

You see, we think of it as a "superfluous", even an "enemy" part, but it also has such an important role, how delicate the evolved structure of the human body is.
