The National Health Service provides free treatment for people living in Britain and gives emergency treatment for visitors.
The National Health Service consists of three main parts:
- the general practitioners
- the hospital and specialist service, and
- local health authority services.
The centre of National Health Service is the general practitioner. Dentists and opticians usually have separate clinics.
There is also a medium-level hospital staff. District nurses give injections, physiotherapy exercises at people’s homes. Ward nurses take care of the ill in the hospital.
Regular medical inspections are held at schools. There also exists a school dental service in every school
Much attention is paid to the educational programmes. Great Britain pays much attention to the qualification of doctors. They are trained at 16 universities
