Explain why an infection may occur in a tissue injury?

An infection may occur in a tissue injury due to the disruption of the skin barrier, which normally protects against pathogens. When the tissue is damaged, bacteria and other microorganisms can enter the body more easily. Additionally, the inflammatory response triggered by the injury can create a favorable environment for pathogens to thrive, further increasing the risk of infection. Compromised blood flow and immune response at the injury site can also hinder the body's ability to fight off invading microbes.
