Health care systems refer to the organized methods and structures that provide medical services to populations. These systems can vary widely between countries, often influenced by factors such as government policies, economic resources, and cultural values. Common types include public health care, where the government funds services, and private health care, where individuals pay for their own care. The main goals of health care systems are to improve health outcomes, ensure access to necessary services, and manage costs effectively. Key components include hospitals, clinics, and health insurance, which work together to deliver care and support to individuals and communities.
