Firewall (medicine)
Firewall (pronounced: /ˈfaɪərwɔːl/) is a term used in the field of medicine to describe a protective barrier within the body that prevents the spread of disease or infection. The term is borrowed from computer science, where a firewall is a system designed to prevent unauthorized access to or from a private network.
Etymology
The term "firewall" originally referred to a wall intended to confine a fire within a building. In the context of medicine, it metaphorically refers to a barrier that prevents the spread of harmful elements, similar to how a physical firewall prevents the spread of fire.
