Final answer:
In a national health system, healthcare is typically financed through government taxes rather than fee-for-service payments, private insurance, or out-of-pocket expenses.
Step-by-step explanation:
The question asks about the financing method in a national health system. In such a system, healthcare is typically financed through government taxes. This contrasts with other methods like fee-for-service payments, where medical providers are reimbursed based on the cost of the services they provide or through private insurance companies where coverage is facilitated by for-profit or nonprofit insurers. Some health systems might also involve out-of-pocket payments where patients directly pay for services. However, the essence of a national health system is its funding through government taxes to provide healthcare services to the citizens, typically without direct charges at the point of use.
