i do't know if your talking of universal health care as a spacifik term for something in usa or about models from uk and other european countries.

heers a poted version of how it works.

doctors and hospitals are paid for by government. So a doctore appontment is free for anyone, if yourking you pay a small amount for every perscription. If nt working the perscriptions are free. If pregnant doctores, perscription, dentist and eye care are free.

a bit out of taxes are used to pay for all thse services, its well worth it as no one dose without. This creatres waiting lists etc. So some have opted for private medical insuransre to vcover costs so to line jump or cue jump and have op quicker.

but no one is left sick with no acess to doctors, hospitals and medicane. Apart from slaging of the healthcare system i just blessed its their in any shape or form and ovverall its quite effective
