How does the health care system of the United Kingdom differ from that in the US?

The healthcare system in the United Kingdom is primarily publicly funded through the National Health Service (NHS), which provides universal coverage to all residents at little to no direct cost at the point of service. In contrast, the United States operates a mixed system where healthcare is funded through both private insurance and government programs like Medicare and Medicaid, leading to significant disparities in access and cost. Additionally, the UK emphasizes preventive care and public health, while the US system is often criticized for its high costs and reliance on private providers.
