How does the skin protect against infection?

How does the skin protect against infection?

The skin acts as a barrier, preventing pathogens from entering the body. It has multiple layers that provide physical protection.

What are some specific ways the skin defends itself?

The skin produces antimicrobial peptides, has a pH that inhibits bacteria, and contains immune cells that respond to threats.

Can you explain the role of skin flora in protection?

Skin flora, or microbiota, compete with harmful bacteria for resources and can produce substances that inhibit pathogen growth.

What happens if the skin barrier is damaged?

If the skin barrier is compromised, it can lead to infections as pathogens can easily enter the body, causing inflammation and disease.

Are there ways to strengthen the skin's protective functions?

Yes, maintaining hydration, using moisturizers, and protecting the skin from excessive sun exposure can help strengthen its barrier.
