The NHS aims to ensure that all individuals have access to necessary healthcare regardless of their financial situation. The NHS is funded through taxation and is one of the largest employers in the world, employing millions of staff, including doctors, nurses, and support personnel. It plays a crucial role in promoting public health, managing diseases, and providing preventive care to improve the overall health of the population.
