A question that has been bothering me for many years: the needle is hollow, where does the meat in the core go when the needle is injected?

Many people do not know where the meat in the needle core goes during the injection process? Let's analyze. It can be concluded from the relevant experiments that the results of using different types of needles during the injection process are different. Whether there will be physical tissue in the needle core depends on the size of the needle. Usually, injections are required for vaccines or diseases. The needles used are very small. After they are inserted into the human body, they are pulled out. There is no so-called physical tissue in the core of the needle. Only very large needles can clearly see the physical tissue. Generally, needles under five millimeters are clean, so there is no need to worry. In addition, the needle of the syringe used has a beveled structure, and the beveled surface penetrates the skin during the injection process. When cutting the skin, it can ensure that the muscle fibers can only be torn from one side, so there will be no muscle hidden in the needle core.
