What is the working principle of the human body, how does the human body work

Convert food into energy and BABA

The basic functions of the human body refer to the physiological functions of the human body, including the following 8, namely: locomotor system and digestive system.

Respiratory, urinary, reproductive, vascular, endocrine, nervous system.

1. Locomotor system:

Performs motor functions of the body, including the body's bones, joints, and skeletal muscles.

2. Digestive system:

It is mainly used to digest food, absorb nutrients and excrete metabolites.

3. Respiratory system:

Performs a gas exchange function to draw in oxygen and expel carbon dioxide.

and has endocrine functions.

4. Urinary system:

Excretes water-soluble metabolites such as urea.

uric acid and so on. 5. Reproductive system:

It mainly performs the function of reproduction and reproduction.

6. Vasculature:

Transports blood and lymph through the body, including the cardiovascular and lymphatic systems.

7. Endocrine system:

Cooperate with the nervous system to regulate the activities of various organ systems in the body.

8. Nervous system:

Harmonize the activities of various organ systems throughout the body.

Locomotor system, god-level system, respiratory system, urinary system, digestive system, reproductive system, endocrine system.

The working principle of the human body is: Qi pushes the blood, and the blood drives the nutrition, that is to say, where the qi and blood can circulate, the function can operate normally, and the qi is walking in the meridians, so the core is the meridians. The meridians are all sick.

It's hard to fall asleep because your (liver function) can go down.

Sleeping lightly is your (kidney function) can go down.

Sleeping and flowing (spleen) can be reduced.

The hair in the sideburns is gray (liver function) can fall.

In the front, the white is (spleen function) can fall.

In the back of the head, the whiteness of the head (kidney function) can decrease.

The pale face is not good.

The redness of the face is not good.

The bluish (liver) is not good.

The blackened (kidneys) are not good.

Yellowing of the face is not good (spleen).

Please be kind to yourself, because the parts are not well matched, and the thieves are expensive, and if you have money, you may not have the goods! Take good care of your body!!

Health is not important, go to the hospital and sober up.

Ergonomics. It is the use of physiological and psychological information to design devices and systems for human use. Its information and principles are widely used in the home, workplace and entertainment, and are the interaction between people and the working and living environment.

research. The goal of ergonomic research is to make human work and life more efficient, and at the same time to promote human well-being. This involves building and maintaining equipment, tools, work, and.

Environmental factors. compatibility, on the other hand, is also considered.

Human anatomy. Biomechanics.

and conceptual and behavioral characteristics.

One of the most important features of ergonomics is its interdisciplinary nature, which combines physiology, psychology, engineering, and more.

Anthropometry.

i.e. the measurement of the human body). The non-psychological aspect of ergonomics is sometimes referred to as human factors engineering. From an ergonomic point of view, the range of topics that can be studied is quite wide, including the following:

Static and dynamic human biomechanics, metabolic and physical work environment, tool use, repeated.

Sexual activity. work, climate and other environmental effects, lighting, equipment and process design, job demands, psychological and cognitive needs. Wait.

Interior design is the best demonstration of the application of ergonomics, which must take into account factors such as the overall space, passages, doors and windows, furniture, etc. In order to investigate the possibility of potential environmental problems in a consistent and rational manner, there is a lot of ergonomic information that can be used to systematically examine the many factors that make up the system in the environment where people work and live.

Does it make sense for the landlord to deliberately ask this kind of question? I think the landlord is deliberately looking for scolding.

The most basic function of the human body is to eat, what is the problem.
