National Health Systems are organized frameworks that provide healthcare services to the population of a country. These systems can vary widely in structure and funding, but they generally aim to ensure that all citizens have access to necessary medical care. They may be funded through taxes, insurance premiums, or a combination of both, and can include public hospitals, clinics, and preventive care programs. In many countries, government plays a crucial role in regulating and managing these health systems. National Health Systems often focus on improving public health outcomes, reducing healthcare costs, and ensuring equitable access to services. Examples include the National Health Service (NHS) in the United Kingdom and the Medicare program in the United States.
