1. Introduction
Health care plays an essential role in maintaining and improving the quality of life across the globe. Whether it’s managing chronic conditions, preventing illness, or providing life-saving treatments, health care systems form the backbone of a functional and healthy society. In today’s modern era, with technology advancing rapidly and life expectancy increasing, the need for accessible, affordable, and quality health care has never been more urgent.
2. What Is Health Care?
Health care refers to the organized provision of medical services to individuals or communities to maintain or improve health. It includes a wide range of services such as diagnosis, treatment, prevention, and rehabilitation.

4.3 Tertiary Health Care
Highly specialized care provided in larger hospitals and advanced medical centers.
- Examples: Cancer treatment, neurosurgery, organ transplants
- Providers: Highly trained medical professionals with specialized equipment
4.4 Quaternary Health Care
This includes experimental medicine and procedures offered in research or specialized medical facilities.
- Examples: Experimental drug trials, complex surgeries, gene therapies
5. Key Components of a Health Care System
A well-functioning health care system includes the following components:
A. Health Care Providers
Doctors, nurses, technicians, therapists, and pharmacists who deliver services.
B. Health Care Facilities
Hospitals, clinics, nursing homes, rehabilitation centers, and laboratories.
C. Health Care Financing
Includes government funding, insurance schemes, out-of-pocket payments, and international aid.
D. Medical Equipment and Supplies
Essential tools such as MRI machines, surgical instruments, and basic supplies like syringes and gloves.
E. Health Information Systems
Technology that enables data management and decision-making, such as Electronic Health Records (EHRs).
6. Public vs. Private Health Care
Public Health Care
