Step-by-step explanation:
The order in which care services should be arranged, beginning at the bottom of the health services pyramid, is: 5) Population-based health care services, 4) Clinical preventive services, 1) Primary health care, 3) Secondary health care, and 2) Tertiary health care. Population-based health care services concentrate on broad issues that affect large numbers of people. Clinical preventive services involve preventing diseases before they occur.
Primary health care represents the first level of contact individuals have with the health system. Secondary health care deals with more serious health complications, requiring specialist services. Lastly, tertiary care is for patients who require hospital care for specialized, intensive treatment.
