Surely every person at least once thought - why do they take blood from the ring finger? And not from medium or, for example, large. Well, there is a very clear answer to this question.
Expert Opinion
Only the doctor can tell everything more clearly and objectively. And that's what the doctors say. The blood is the same everywhere, but it is customary to take it from the ring finger for analysis, because a puncture, which implies damage to the integrity of the skin, is fraught with infection. Of course, not always, but anything can happen. So, the inner shells of the little finger and thumb are specific - they are directly connected to the one that belongs to the brush. And if the infection gets into them, then its spread to the whole arm is ensured.
This is why blood is taken from the ring finger. Its shell is isolated. And even if the infection gets there, it will be localized. And this makes it possible to quickly suppress it and avoid unpleasant consequences.
However, there is another answer to the question of why blood is taken from the ring finger. It is believed that the blood vessels located in it go directly to our main organ - the heart. Therefore, they try to take blood from it (although it is still permissible to use the index and middle). And the reason is very clear. After all, cardiac activity is the basis of all blood circulation.
Practical approach
This is not all the reasons why they take blood from the ring finger. The second, no less important, lies in its minimal working capacity. But really - where is the ring finger used? When a person writes, he is not involved. When typing on a computer - also (with the exception of journalists using all fingers). In everyday situations, it is also not required: when delivering money, slicing bread, dialing SMS on the phone, etc.
This means that the skin on the ring finger is the thinnest. And the puncture, respectively, is not so painful. And yet this finger moves less than others, which contributes to the speedy healing of the wound and reduces the likelihood of infection.
Does the hand matter?
This is also an interesting question. Many are interested - why take blood from the ring finger of the left hand? Everything is simple. Because most patients are right-handed. And, therefore, their right hand is constantly involved in the performance of a particular business. And so that after the procedure it was just as convenient and painless to do something, doctors use the finger of the left hand.
But! If a person is left-handed - everything is exactly the opposite with him. And he needs to warn the doctor about this - ask him to take blood from the finger of his right hand. As mentioned at the very beginning, our biological connective fluid is the same everywhere. So the approach to the procedure in this case is purely practical.
What should be considered when passing an analysis?
So, why take blood from the ring finger - clearly. Now it is worth listing the factors that a person should warn a doctor about before taking an analysis from him. And here is what the patient must say:
- Does he play sports?
- whether it is subject to sharp physical exertion, going against the usual sedentary lifestyle;
- whether he took medications for 2 weeks before blood donation (since even regular painkillers or sleeping pills can distort the results of a medical study);
- Is he a vegetarian?
- Does it have chronic diseases?
- Does he have carious teeth?
All these nuances will be taken into account when decoding the analysis. Girls are even encouraged to clarify information about their monthly natural processes. Since the composition of the blood is affected by every process that takes place in the body - even one that seems insignificant.
Interesting Facts
So, what factors need to be warned by a doctor and why blood is taken for analysis from the ring finger is clear. Finally, it is worth paying attention to an interesting topic, namely, the features of the ring finger.
At the beginning of the article it was said that he is the most motionless. And this finger is usually involved along with the rest - for grabbing. Why? Because the fingers are united by their common tendons. Nameless can be used separately, except in the case of playing musical instruments. And with professional typing.
It was also said above that vessels from the ring finger lead directly to the heart. But the Egyptians and Romans, by the way, considered this not so much a physiological feature as a reason for their special purpose. Having interpreted this specificity in their own way, they began to wear wedding rings on their ring fingers. What is practiced to this day.
In the end, I would like to say that the fourth finger is not called the “fourth ring” in all languages. Most often it is called "ring" or "ring". In English, for example, it sounds like this: “ring finger”.
