Have you ever had a very strange and slightly scary question come to mind during an injection: "When the needle is stuck in my flesh, where does the part of the meat that is occupied by the needle core go?" ”
If this question has been bothering you, don't worry, today we will answer this question with a little humor and a lot of scientific knowledge.
First, let's clarify an important concept: when we say "injection", we are actually referring to a process that uses a needle to inject a drug into the body.
The diameter of the injection needle is generally very small and cannot be clearly seen with the naked eye.
The first misconception that arises from this is that most people think that after the needle is inserted, a piece of "meat" equivalent to the diameter of the needle will be squeezed out or disappear.
Actually, this is far from the case.
The muscles and subcutaneous tissues of the human body have very good elasticity and flexibility, which is to protect our body from external forces.
When the needle penetrates the ** and muscle, the tissue naturally bypasses the needle instead of being "squeezed out" or "gone".
As the needle passes through, the tissue separates slightly, just as the surface of water naturally separates when an object passes through it.
So, when the needle is pulled out, how is that piece of "meat" recovered? This involves the body's ability to repair itself.
The pinhole is small, but it is a tiny wound.
After suffering *** damage, the human body will immediately start the healing process, and platelets and various cells will gather at the wound site to help stop bleeding and repair the damage.
Over time, the pinhole will gradually heal and may even leave no traces.
Interestingly, in this process, the "meat" is not consumed or removed, but through a series of reactions and self-repair functions of our body, a small but complex self-recovery process is completed.
Now, let's add a bit of humor: suppose that every time you get an injection, a small piece of flesh really disappears, then the thinnest people in the world are not bodybuilders who regularly work out, but patients who regularly get injections.
So, the next time you're injecting, think about this joke that might ease your nerves.
Before we wrap up this topic, let's take a closer look at the syringe design philosophy adopted by modern medical care.
Modern medical needles are precisely calculated and designed to reduce damage to human tissues and improve the efficiency of drug injection.
The sharpness of the needle, the angle, and even the choice of material are all designed to make the injection process as gentle as possible and reduce discomfort for the patient.
Through this article, you will not only learn about the scientific answer to the question "where does the meat in the needle core go when you inject it", but also gain a deeper understanding of the body's self-healing ability and modern syringe design.
The next time you or your friends have the same question, I believe you can share this knowledge with confidence and show your humor and wisdom.
