What is the tendon that is spit out by bleeding the base of the tongue to extract acid?

First of all, the tongue root bloodletting is mainly to prevent thrombosis, many early rural people will think that thrombus gathers under the base of the tongue, and the thrombus can be released through the tongue base bloodletting to achieve the purpose of preventing thrombosis, but in fact, the blood clot is not evenly distributed in the body, and the blood circulation of the substances that form thrombus has been flowing, and the blood released contains thrombus, but it cannot prevent new thrombosis.

Many people collect the patient's money for the purpose of treating the disease with home remedies, and indeed some home remedies have the effect of ** disease, but there is no scientific basis for bloodletting at the base of the tongue to prevent blood clots.

In addition, there are more bacteria in the mouth, once the bleeding at the base of the tongue is not operated well, it is easy to lead to infection, and then it is not only a problem of blood clots, but also a serious case.

First of all, it needs to be clear that sublingual bloodletting is basically no good for the body, and spit out something as black as meat tendons, which is actually produced after blood coagulation, which is a normal physiological reaction.

There is also a substance in the blood called fibrin, which captures and traps blood cells in the blood, causing the blood to change from liquid to solid.

Thrombosis is a worldwide problem, developed countries are not possible, the prevention of thrombosis is mainly from the change of life and rest, at present, it is known that the way to really prevent thrombosis is exercise, increase the amount of exercise, the formation of thrombosis will also decline proportionally.

In addition, people with precursors of blood clots must quit smoking and drinking, and maintain blood pressure, so that they can prevent blood clots from symptoms, rather than following some false "home remedies".

In fact, it is produced after blood clotting, which is a normal physiological reaction.

These should be vascular nerves. These are normal.

Maybe it's a substance on the tongue coating that has something to do with blood.

It could be something formed by blood clotting.

It must be blood vessels, nerves and stuff.

It's just one of the nerves in the vessel.

After bloodletting, it is produced by the blood clotting.

Because it's something formed by blood clotting.

One by one, it should belong to the blood vessels.

Usually it is clotted blood.

To drive a car, you need to start the engine of the vehicle, then hang up the gear of the vehicle, and then accelerate the vehicle through the accelerator pedal, and then decelerate the vehicle through the brake pedal, and also stop the operation through the brake pedal, the specific operation steps are as follows:

1. Press the brake pedal.

2. Press the one-button start button.

3. The instrument lights up and the vehicle starts.

4. Put the automatic gear lever in the D position and enter the automatic mode.

5. Press the accelerator and the vehicle will automatically skip gears.

Make sure there are no obstacles or people around the vehicle before getting into the car. After the key is turned to the ON position, let the vehicle power on for a few seconds to complete the self-test. Then apply the brakes and turn the key to start the vehicle (automatic).

After starting, the gear is engaged in D gear, slowly release the brakes, and the vehicle moves forward.

If it is a manual transmission, you need to press the clutch before starting the engine, then engage the 1st gear, slowly release the clutch at the same time, transfer the right foot from the brake pedal to the accelerator pedal, and slightly refuel. The throttle and clutch work together, and the vehicle moves slowly.

1. When starting, make sure that the brake has been released, slowly lift the clutch, and do not give oil.

2. While driving, slowly press the brakes and downshift.

3. When encountering a red light at the intersection, the operation at this time is the same as the operation at the start.

4. The red light turns to the green light, or the starting operation.

5. When turning around at the intersection, reduce the gear, generally 2 gears are enough, and the circle is larger, and it will pass directly to death.

Manually shake the stick left and right to see if it is already in gear. The automatic gear observes the gear situation and marks it very clearly. For the sake of insurance, you should develop the habit of manually stepping on the clutch and braking and ignition, even if the car is in gear, there will be no problem with starting this way.

Automatic transmission applies the brakes. That's why you can change your seat first and then light the lighter.

Automatic vehicle driving method: 1. When the gear knob is in P (or N) gear, the key is played;2. When moving gear D forward gear or R backward gear, you must apply the brake (brake) with your foot;Otherwise, it can't be moved;3. After the gear is moved into place, lift the brake (brake);The body begins to move forward (or backward);Then start refueling the drive;4. When you need to stop, directly press the brake (brake);The body stopped;5. Stop for a short time and directly press the brake (brake); For a long time (more than 2 minutes), it is best to move the gear in N gear and lift the brake (brake); Use the handbrake to stop the car; 6. In the gear, the letter P is parking (parking), R is reversing, N is neutral, and D is forward; If it is a manual automatic transmission + is to increase one gear - it is to lower one gear; 7. Downhill and uphill can always use D gear, and use the brake and accelerator to control the speed. 8. When waiting for the red light or stopping production for a short time, the gear is hung in D gear and then the brake is pressed; If the time is slightly longer, more than 2 minutes, it is better to move the gear to N gear and lift the brake (brake); Use the handbrake to stop the car;

The steps to drive a car are actually quite simple, there are only seven steps: 1 pedal; 2 hanging; 3 dials; 4 presses; 5 loose, 6 put, 7 plus; 1 step, refers to stepping on the clutch; 2 hanging, that is, hanging; 3 dials, is to dial the direction light; 4 presses, is to press the horn; 5. Loose, is to loosen the handbrake; 6 put, is to put clutch; 7 plus, is refueling, but remember, (5, 6, 7) three is a joint action, to cooperate properly, so that it will not turn off, so that there will be no great vibration, here is just to teach you to be familiar with the operation steps of driving, if you have not gone through formal training, then I suggest you still go to a driving school, where there are experienced instructors and practical operations, there are also a lot of driving knowledge, such as seeing the four roads, listening to all directions, various road signs and icons, etc., and it is safer to learn there.

You are a beginner to give you advice: pull the handbrake, see if the gear lever is in neutral, not in neutral such as hanging, then ignition, then step on the clutch to the end, hang into first gear, slow release of the clutch must be slow, (don't like the people upstairs said quickly loosen to one-half, you are a novice, unfamiliar with the car, the result of this I estimate that 80% is flameout) and then feel a little shaken on the clutch to stabilize the clutch do not move, must not loosen the clutch Oh, then loosen it and turn off. Then hurry up and release the handbrake, gas pedal, the car can go, and when the speed is up, you can release the clutch to finish, so that the start can be started regardless of whether you start on the ramp or not, and the car will not retreat

It is recommended to go to a driving school to learn, here teaches that you are not responsible for your safety and the safety of others.

A1A2D is the highest level of driver's license, basically any car can be driven, (trains, planes, tanks, excavators, can't drive).

1. The landlord asked: What are the classifications of driver's licenses? What in turn.

A: It depends on the criteria for classification.

According to the classification of the issuing country, there are two categories: Chinese driver's license, overseas driver's license;

According to the type of driving, there are aircraft driver's license, motor vehicle driver's license, construction machinery driver's license, ......The landlord should be asking for a quasi-driving classification, right? There are 16 types in total. The classification of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" is as follows:

A1 (large bus), A2 (traction), A3 (bus), B1 (medium passenger), B2 (large cargo),

C1 (small passenger), C2 (automatic transmission), C3 (low-speed cargo), C4 (three-wheeled vehicle), C5 (automatic transmission for the disabled),

D (three-wheeled motorcycle), E (two-wheeled motorcycle), F (moped), M (wheeled self-propelled machine),

N (trolleybus), P (tram).

2. The landlord asked: What is the order from simple to difficult?

A: It's hard to say if you classify it according to the level of difficulty.

Because for different people, the difficulty is also different.

Among the above-mentioned categories of driver's licenses, the ones that can be applied for at the time of initial application are:

p、n、m、f、e、d、c5、c4、c3、c2、c1、b2、a3。

The rest can only be obtained by adding a driver.

The most demanding of these is A1.

3. The landlord asked: What are the conditions for taking these certificates?

A: First of all, you must be a resident or temporary resident in Chinese mainland.

Secondly, there are certain requirements for physical health, mainly eyesight, color discrimination, limbs, etc.;

Then there is a requirement for age.

1: Adjust the driving postureThe correct driving posture is very important for safe driving, which can not only eliminate the fatigue of long-term driving, ensure good driving vision, but also make the driving action more accurate, fast and reasonable. The driving posture is mainly related to the steering wheel and seats.

Once in the driver's seat, you should first sit deep behind the seat with your waist and shoulders resting on the back. Feel the right distance between the front and back of the seat and the angle of the backrest, then extend your arms forward and naturally hold the sides of the steering wheel. In this case, the wrist must be able to bend freely and move freely.

There should be a certain amount of room for movement in the legs, and it is effortless to press the clutch pedal, brake pedal or accelerator with your feet, and the body does not have to lean forward, so the position is basically suitable at this time. If it doesn't fit, you can slide the seat position back and forth, or adjust the angle of the back of the chair to meet the above requirements.

2: After the driving position is adjusted, the next step is to grip and operate the steering wheel. The position of the steering wheel is optimally bent with both hands in the direction of 3 o'clock and 9 o'clock (i.e. horizontal), as this gives the arm sufficient area of movement to operate the steering wheel quickly.

Don't hold the steering wheel tightly, but gently hold the outer edge.

Many novices always hold the steering wheel tightly, causing a lot of sweating in their hands, affecting the accuracy of the action, and it is easy to hit the steering wheel abnormally when changing gears, burying the hidden danger of accidents.

3: The vast majority of novices drive for the first time on the road (taking manual transmission as an example) is different from the car they drove when they learned to drive, so they are very unfamiliar with the gears. If you don't take the time to familiarize yourself with the gears, the direct consequence is that you don't know how many gears you are engaged in when driving, and you often look down at the gear lever, which can easily cause traffic accidents due to distraction.

Especially when encountering complex road conditions, due to tension, it is easy to hang the wrong gear and cause the ignition to stall, so you must be familiar with the gear before going on the road for the first time.
