Why is it dangerous to remove an object from a wound?

- rubber glove with water;
Pierce a rubber glove filled with water with a nail. Observe that the liquid either flows out of it very slowly or doesn’t flow at all.
A wound is a violation of the integrity of the skin or mucous membranes of the body caused by injury. The injury can be caused, for example, by the penetration of a foreign object into the body. The formation of such a wound can be demonstrated clearly and painlessly using a glove filled with water and a nail. The waterlogged glove plays the role of body tissues, and the nail is the foreign object. Due to the fact that the glove is elastic, it fits snugly to the nail and “seals” the hole, preventing the liquid from flowing out quickly, but if you pull the nail out, the water will start leaking rapidly from the fresh “wound.” The same thing can happen with a real wound – when an object enters the human body, the integrity of the skin, muscles, and even blood vessels with arteries are violated. A foreign object, just like the nail in our experiment, seals the wound and partially stops the bleeding.
