National Health Systems

A National Health System (NHS) is a government-funded health care system that provides medical services to all residents, funded primarily through taxation. It aims to ensure everyone has access to necessary health care regardless of income or social status. These systems typically include a network of hospitals, clinics, and health professionals working together to deliver comprehensive care — from preventive services to emergency treatment. The goal is to promote public health, reduce financial barriers, and ensure equitable health care delivery across the population. Examples include the UK's NHS and Spain's Sistema Nacional de Salud.
