Why does the job of the immune system make a more difficult on the skin is damaged (such as from a large open wound or a severe burn)?

When the skin is damaged, it compromises the body's first line of defense against pathogens, making it easier for bacteria and viruses to enter. The immune system must work harder to prevent infections, as the damaged area is more susceptible to microbial invasion. Additionally, inflammation and the healing process can divert immune resources, complicating the body's ability to respond effectively. This increased demand on the immune system can lead to a higher risk of complications and prolonged recovery.
