Because it is the first thing a pathogen (a bacteria, virus, fungus, or parasite that causes disease) must overcome before it can gain access to your body. The physical defenses include your skin and mucus.
Hair does not feel pain when cut, as it lacks a nervous system. However, the hair follicle and surrounding skin may experience pain if cut during the process.
The sharp, knife-like edges of broken glass can cause deep, devestating lacerations, which in turn can result in rapid blood loss if major arteries are cut. Broken glass is also unstable in that it is easily rebroken and can leave shards in the body that can produce further injury. The broken glass is non-sterile, so i can easily be a vector of infection by tearing open the body's best defense, the skin.
When you have a cut, the epidermis, which is the outermost layer of skin cells, is punctured. Beneath the epidermis lies the dermis, which contains blood vessels, nerves, and connective tissue. The injury disrupts the protective barrier of the skin and can trigger an inflammatory response to initiate healing.
Mitosis helps a cut heal by facilitating the rapid production of new skin cells to replace those that were damaged or lost during the injury. When a cut occurs, the body initiates a healing process that includes the activation of nearby cells to undergo mitosis, allowing for the proliferation of new cells that migrate to the wound site. This process is essential for restoring the integrity of the skin and promoting tissue repair. Ultimately, mitosis is crucial for regenerating cells and ensuring a swift recovery from cuts and injuries.

New skin ! If you cut yourself, the body despatches loads of platelets to the wound site to stop blood oozing out - which form the scab. This is a barrier to stop infection getting into the cut. Underneath the the scab, the body sets to work forming new skin and blood vessels to repair the cut.
